Anja and family, Jules was a great man and he will be greatly missed. I will cherish the times I got the privilege to be around him and sharing a glass of wine over simple conversations. I truly enjoyed and respected this man and will miss him dearly. My condolences go out to you and your family.

Tressa D'Ottavio

I am blessed to have been counted among Jules' students. I always enjoyed hearing of you and Julia through Jules. He was SO, SO proud of you both (and Anja, too). What a wonderful man! I lost my Mom very suddenly in 2006 and I think I understand your sense of shock and grief. Hold fast to your family and friends, and know that you're not alone in your grief.

Kristen Constant

The news is very saddening for me. Jules and I have known each other for 20 years. And though we used to play tennis together, our first real work collaboration has been this past year in organizing a conference that will take place in Lake Geneva, Wisconsin, in October. My prayers are with you and your family.

Mark C. Petri

I’m deeply saddened by the loss and may God rest Jules soul in peace. I offer my deep condolences to the family. He was a great person, a very good mentor to young scientists like us. Argonne will miss the services of such a great scientist.

Vivek

I was so terribly saddened to hear of Jules' death yesterday. I worked with him at the Engineering Conference organization, and know him as a great scientist, a true volunteer, and an awesome colleague. He had a passion for his work in materials science and with ECI that really showed through. He also was a guy you loved to socialize with, interesting and with an excellent sense of humor. I will miss him greatly. My most sincere condolences to you and your family. God bless you all.

John Aunins

Please give my love to your mother. She is in our thoughts along with you and Julia and your families.Your father was a dear friend and kindred spirit. I will miss him very much.

Barbara Hickernell

He was so important for my life... I took an academic carreer because of him. He showed to me what was to be a scientist, and I loved it. Because of this, on March 13th I am sworn as Rector of my university, barely 25 years afterwords I showed up in Argonne for the first time as a Ph.D. student. His message last wednesday was of pride and support, as always. I met my wife, Madelyn, in his lab. I still remeber the day. 'I have arranged a girlfriend for you...'. This was the first day of my Post Doctoral year at ANL. I always say that I have two fathers, my biological father, and Jules, if you and Julia allow me to borrow a bit of him, in terms of carreer and professional life. I will miss him a lot.

Antonio Ramirez de Arellano

I am deeply shocked by this news, I know his mother and father lived a really long time and he was always so lively. Take care, my thoughts are with you and your family.

Jackie Johnson

You and your family are in my thoughts and prayers. I am so privileged to have known your father. He was a wonderful friend and an exceptional scientist, engineer, and researcher. I have so many fond memories of Jules, and most of them are of us talking about his grandchildren, my children, and our families. He had such energy and enthusiasm; it was impossible not to enjoy any time spent with him. His passion for his work was unmatched. Jules had a unique ability to bring ideas and people together with his enthusiasm and expertise. He will be missed.

Susan Rogers

We are lost star from our living. Your father was my the first JOB in the USA as an interviewer. I am getting the same feeling that all we are having. He is at the rest in heaven. The most wonderful as a person, father (because we have know What he always talking MD-PhD son.. He soring leg and arm, but sons in NURO. Jules said. He has put your Scientific papers in the ANL-212 Building, too. Steve Rothman, Norm Peterson, Lehn Rehn, Paul Okamoto, S-K Chen, Wayne E. King, Jong-Hee Park the most wonderful scientist in the world gathered around JULES the great man... How's mother. I am so tearful losing the best friend! Rather crying, I am sending the greatest admireance to all around JULES. That is 0.01% of your Father, JULES

Jong-Hee Park

I am shocked and saddened by this news. Jules and I had lunch together just two weeks ago and he seemed fine. I had come to know him quite well during the last few years and I had a high regard for him both as a scientist and a friend. This is a deeply felt loss for all of his many friends but particularly for his family whom he loved. My sincere condolences.

Dieter M. Gruen

It is a great loss that Jules is no more with us. I had known him since 1973 when I worked at Argonne. Please convey our condolence to your mother and may God give all of you strength to bear the loss.

Raj Singh

Dear Mark, Julia, Anya and all the family, Alheli and I are so saddened by the news of the passing of my favorite cousin. Such a gracious soul should not have left us so soon. Although we cannot attend the memorial, our thoughts and prayers are with all of you.

Love, Amanda and Alheli Carles (Hyman)

Lieber Mark, Julia und Tante Anja, noch immer bin ich ganz geschockt von der Nachricht und kann es gar nicht glauben, dass wir Jules nicht wiedersehen werden. Auch wenn wir in Deutschland so weit weg von Euch sind, denken wir oft an Euch. Gerade vorgestern war Peter bei uns in Frankfurt und hatte von den Urlaubsplänen in Italien berichtet. Ich persönlich bedauere es sehr, keine Gelegenheit gehabt zu haben, Euch in Amerika zu besuchen, jetzt fehlt ein bedeutender Teil der Familie. Insbesondere Dir, liebe Tante Anja, wünsche ich viel Kraft und die Unterstützung Deiner Familie. Alles Leibe

Birgit Eickhorst und Familie

I knew Jules for well over a decade and worked with him closely during that period. We traveled together on occasion and I met your mother during some of those trips. His sudden loss is a sad news to many of us at Argonne, I can only imagine the shock to you and your family. Please accept my condolences.

Tanju Sofu

Needless to say, this news is a shock to me. It was just last summer that I visited with Jules to present a seminar at ANL. He was a gracious host. I had expected, and looked forward to, many more years of collegial work with Jules on the Engineering Conferences International. It is sad to realized that this will not happen. While a sudden death avoids the pain of a lingering illness, it is a shock and a sadness for all family and friends. While I do not personally know you, your sister or mother -- I would like to extend sincere condolences and my personal sympathy. We all are saddened and will miss Jules.

John C. Chen

We are very shocked and sad to learn of the death of your very energetic and vibrant father. One of my volunteer jobs is to be President of the ECI organization and Jules could always be counted on to participate and to contribute in significant ways. For many years he was the very successful Chair of the Conferences Committee and more recently a very active Board member. We will miss him greatly

Barry Buckland

I would like to convey my deepest condolences to Jules family. I am so sorry. Jules was a leader in our field of science and always full of support.

Manfred Martin

My deepest condolence to you and all of your family. Jules was not only a good scientist, he was also a great colleague. He had a sense of humor, a wide ranging intellectual curiosity, and honesty ( you could take anything he said to the bank). Traveling with him was great fun.

Harvey Drucker

I would like to express my deepest sympathies to you and your family on the loss of your father. In January I had an opportunity to have dinner with Jules in Florida at the American Ceramic Society meeting. We discussed future research activities in electric vehicles. Jules was also mentoring me in regard to setting up a conference in Japan next year. Amid all our discussions on science and technology, Jules would always interject a few thoughts about his children and grandchildren. He was a proud father and grandfather and a very enthusiastic scientist.

Mike Lanagan

We are shocked and saddened to hear about Jules' passing. We have enjoyed the pleasure of collaborating with him scientifically and we will miss his guidance. Our deepest sympathy.

Frances E. Lockwood

It took me a while to get around to writing this because I was out of town and needed to be at my desk to dig up the attached pictures, many of which were taken at truck shows where we were pushing idling reduction. And because I just had nothing to say that could possibly capture my feelings. The news hit my email while I was sitting in the ICU with my mother (who mercifully died Tuesday at the more appropriate age of 91) and I was totally blown away. This is just not right… Jules was the one guy at Argonne who wouldn’t take any crap from anybody. He always told it like it was. On raises: “What difference does it make if it’s one pizza a week or two?” He was the one guy who supported me unconditionally when I got into trouble because a company complained to the lab director (and DOE general counsel and U of C president etc.) because I questioned their business plan (they since went belly up—twice!). In sum—he was a good guy and will be missed. May his memory be a blessing.

Linda Gaines

It is with great sadness that I have learned about Jules’ death, a great loss indeed. As a beamline scientist at the APS I did work with many users but Jules certainly was one of the most inspiring collaborators. He motivated by his genuine interest in science and at the same time always honored the personalities of the collaborators, often expressed by his never failing humor. I returned to Germany earlier this year and was looking forward to running into Jules during one of my upcoming visits at ANL. Sadly this will not happen but he did leave a spirit that will be of great help to me and many others in our lives.

Ulrich Lienert

It’s been hard for Stan and me to get past the shock of Jules’ sudden death. He was also so full of life and enjoyed it to the fullest. He was a real mensch, and we’ll miss him terribly. We are unable to attend the memorial service, but I thought you’d like to hear about some memories we have of Jules. I know one of his (and your) favorite restaurants was Alinea, but we convinced him to give Tru a try on a visit to Chicago when Stan was with me. Such unobtrusive service, such wonderful food, such quiet in a restaurant so that we could talk and not scream at each other, such fabulous wine! I remember that Jules tried to track down that wine, but it had been long sold to out and was totally unavailable. Such a connoisseur!

In 2004, when Linda Gaines and I put on the National Idling Reduction Planning Conference in Albany, Stan again joined me, and Jules was also there. The two of them had snuck away to smoke Arturo Fuentes (you’re not supposed to know about that) in the pleasant shade of a tree on a beautiful May day, when I sent an inventor over to talk to Jules. Sure the guy didn’t understand the laws of physics, but Jules was patient with him and pissed at me, but everyone got over it. And those trips to D.C. -- Jules felt he needed to conserve travel so he’d get up before the chickens, fly to D.C. on the 6 a.m. plane, and as soon as he got to where I was camping in Jim Eberhardt’s office, he’d check his flight home and try to get out earlier. After all the security courses I had to take at the lab, I was always nervous about opening email that didn't have a subject line. Apparently, Jules felt that filling in the subject line was a waste of electrons so he almost never hinted at what the email was about. You had to open it to find out. Just a quirk in his software, I suppose. He loved to tilt at windmills, but we loved his curmudgeonly ways. He loved the good life (I can’t speak about fast women): good wine (his Social Security money, he told us), good food, traveling the world for business and pleasure. He loved you, his family, and every Amadeus very much, and I always envied the fact that he took them on wonderful trips and to fabulous places. As I said, I’m sorry we won’t be able to join you in Sunday to tell you our stories in person, but we’ll be there in spirit. His death is a loss to his friends and to many people worldwide.

Terry M. Levinson

Our deepest condolences for the sad passing of Jules. We lost a great friend. A loving friend. We will also remember him as a very good man and a good father. He was so proud of Mark, Julia and the grandchildren. Every time we met, he would tell us all your achievements with such pride and happiness. Over the years we always competed on who had more grandchildren, and he managed to always be one-ahead of us. And, you certainly know, that every conversation had to have a couple of new good jokes. So, before calling him, I always had to prepare myself. We were shocked and we will miss him dearly.

Fanny and Ricardo Schwarz

I was saddened to hear that your father passed away. I worked at the Laboratory for 38 years and retired nearly five years ago. I had the pleasure of knowing your father who collaborated with staff in my division as well as my boss, Ed Daniels, Energy Systems Division Director. In fact, I shared a table with Jules at a retirement workshop and we talked about the possibility of retirement and life after Argonne. My sister, Denise Moores, also worked with Jules in Bldg. 212 and we both share the same appreciation for his "spunk" and his way of making the job fun. My deepest sympathy to you and your family during this difficult time. I hope it comforts you to know that your father will truly be missed by so many friends and colleagues.

Midge Urban

I am Jean Philibert a colleague of your father. We had been working in the same field of materials science for many years. My wife, Yvonne, was a god friend of your mother : she remembers several visits in US or France or Japan they made together, even one in Paris with your sister Julia. My wife and I were deeply upset to learn of the depth of Jules and send you and your mother Anja our deepest sympathy and our most sincere condolences in your very sad loss.

Jean Philibert

I worked with your father and Ken Goretta for several years on research and published many papers. I stayed two weeks in your old house when your mom and dad were in Europe and taking care of Amo. Sad that Amo passed on. I also stayed a few times in the new house with your parents. Your dad was a great guy. He was one of the few people who could enjoy life anywhere he was; at home or at conference or playing tennis. I remember the one time I was working at Argonne with Russ Cook doing an experiment and your dad called up to see how it was going. We said we got a data point. 10 minutes later he was in lab ripped the strip chart off and ran up stairs to calculate something, came down 10 minutes later yelling that we got a good result. He was intense which I liked. He was very kind and thoughtful. I had not seen in him a few years but lucky to see him in January at a conference. We had dinner together. I never thought that would be the last time. Ken and I thought Jules would go to 100. I learned a lot form Jules about research and more importantly about life from him. I will miss him. I hope your mom will be okay. She is a very nice person. He will be missed. My condolences to the family. I will send donation to requested place soon.

Jeff Wolfenstine

I am so sorry to hear your huge loss. I have enjoyed the pleasure of collaborating with Dr. Routbort for last couple of years. He is such a gentleman, scholar, judge and good leader. We will miss his great guidance. May peace be with you all at this difficult time.

Gefei Wu

We are shocked and saddened to hear about Jules' passing. We have enjoyed the pleasure of collaborating with him scientifically and we will miss his guidance. Our deepest sympathy.

Frances Lockwood

I was shocked to hear the sudden news about Jules' passing. It seems like he has always been at Argonne, ready to offer a useful suggestion or idea. Attached are photos that I accumulated over the years, mostly at Section birthday parties or lunches. I may print them and put them on a poster board to show.

Robert Erck

My deepest sympathy in the sudden loss of your father. I didn't work closely with Jules, but it was always a pleasure when I had the opportunity to work with him - usually in helping to bring in research dollars. I appreciated his dedication, his extraordinary knowledge, his creativity, his mentoring of younger staff, and his wonderful (if quirky) sense of humor. He was one of those rare people who loved his work. Why else would he be working full time when most of his contemporaries had retired a decade earlier. He loved science - or as he said to me on several occasions, he loved very good (read expensive) wine. Perhaps both. Whatever, he will be missed as a colleague and as a friend.

Larry Johnson

I have such fond memories of Jules who was an inspiration for me in many ways, and his passing will be a huge loss for Argonne and many will miss him and not the least will be me.

Michael Rechtin

In recent years, I had the privilege of knowing and working with your father. I spoke with him at Argonne two days before his abrupt passing. We in his group at ANL are in shock as you must be as well. As you know, your father was a unique person who enjoyed people, science and wine (probably in that order). He will live on in our hearts and memories. I am attaching a few photos that I found from happier times.

David France

I am still trying to accept the idea he is not coming to work anymore. I would love to speak some words on Sunday to express how wonderful he was taking care of his postdocs and students. I can speak in my name and in the name of Antonio, Felipe, Joaquin and many other foreigners who came here because of him and found a teacher and a very good friend. He treated us like family and that is something we will never forget. I am sure I have some nice pictures and videos of your father. I remember him dancing flamenco in my wedding drinking wine and having a great time. I will try to collect them in the next couple of days and send them to you.

Maria De La Cinta Lorenzo Martin

I send my most sincere condolences to you, your mother, and your family. I have known Jules for about 5 years working with him on ECI. He is going to be so missed by everyone. He was such a talented man who was also so kind, supportive, and a great wit. I always looked forward to seeing him in NYC every few months. The team will not be the same without him.

Joye Bramble

Lakshmi and I offer our deepest condolences to you and your family, especially Mrs. Routbort. A few years ago, Jules and I won an award, and we all sat at the same dinner table during the award dinner, when we got a chance to meet Mrs. Routbort. I have only known Jules for the past ten years or so, we wrote many papers together and several patents and he was kind enough to host several of my graduate students. One of these students, in particular, John Spirig and Jules became quite close, and John took Jules' parting particularly hard. My fond memories of Jules are because of his wit, he always had a come back line. I remember one long discussion with the patent attorneys, and Jules summarized our discussion by saying that no one since Newton should have received a patent, a comment that concluded the discussion. Jules visited me in Columbus not too long ago, and over a few glasses of wine, Jules reminisced about his recent trip to Napa valley and the family vacation that all of you took together. He was at his finest when he talked about you and your sister, how proud he was of you, and how happy he was to be with his family and grandkids. We will all miss him dearly, however, he has left us a treasure trove of memories, and I hope with time, your pain and loss will diminish as you remember all the fun time that you have had with your father.

Prabir Dutta

The news came as quite a shock to me as I was planning on meeting with him later this week. I knew Jules when I was a graduate due to his name in the field, but also since he was a friend of my advisor. Following school I came to Argonne and worked a building over from his office, but always found a reason to walk over from time to time. He gave me great advice and guidance as I started my career here. I will miss my conversations with him, both scientific and personal - and his sense of humor regarding the way things are run here!

Brian Ingram

I can't imagine how difficult it must be for you and your family and especially your mother to deal with the suddent loss, and I can't begin to express what it means to me. I can't offer any personal words suitable for sharing. Perhaps something Jules' great friend and once-in-a-lifetime colleague, Steve Rothman, once said is fitting. He admitted he would never say it to Jules directly, but in Steve's opinion, Jules managed better than anyone he knew the balance between his family and work lives, between his two passions. Your father was indeed the most broadly capable person I ever knew. And one of the warmest and kindest. Nan and I miss him and our hearts go out to you.

Ken Goretta

It was a shock to me when I received this email from Mark, Dr. Routbort's son, and I just could not response to this message. I would like to share something with you the Dr. Routbort I know. I got to know Dr. Routbort fair late comparing to you and other colleagues around him. It was at Boulder 2007 in a conference I met him the first time.

Back then he was already a well established scholar but he still took time to learn my work on nanoparticles and nanofluids. He asked very detailed questions just like another graduate student from his true curiosity in science. He even invited me to work with him at Argonne on Nanofluids. I was very excited that he thought I have done good work and gave me the great opportunity, but since I already started working at University of Toledo, OH, as an assistant professor, so I lost that precious opportunity to learn from and to work with him. The next time I met him was 4 years later at Rapid city, SD. I met him again and surprisingly he still remembered me. I was amazed by his memory and chatted with him about my research and his research at Argonne. Then he said I should visit him and introduce my work to his colleagues and group members as well as seeing the work he had been working on at Argonne. So I visited Dr. Routbort, you and other colleagues in Feb. 2012. He also invited me to his home and Anja cooked a very delicious dinner for me that night during my visit.

Dr. Routbort has been such a great mentor and friend for me and I recognize that words, however kind, cannot mend the heartache Anja, Mark and Julia must feel, but those of us who care and share their loss wish them comfort and peace of mind and hope that they may find strength in the love of family and in the warm embrace of friends.

Calvin Hong Li

I send my deepest sympathy and want you to know that I have many wonderful memories of Jules. He has played a very important role in my life, as well as in many other colleagues’ life. He was an extraordinary man, a dedicated professional, great scientist and generous with his humor, time and friendship. He will be missed.

Julian Martinez Fernandez

Jules was in my Tribology Group, and I'm truly sorry about the sudden loss that we had last Thursday with the passing of your father. Jules was very well liked at Argonne - I've known him since I joined Argonne in the 1970s and we will all miss him dearly.

George Fenske

Jules' sudden passing is still a real shock to me and a big impact to APL! He was a dear friend and a valued colleague of mine - one we had expected to be with us for many more years.

Nghi Lam

Please accept my deepest sympathy on Jules sudden passing. I myself was very distressed. Anja, you know I have known you and Jules for a very long time. I have greatly enjoyed this friendship, both on and off the court.

Mark Kirk

My Dear Anja, Only you will guess how sad I was to receive Mark’s email. It’s not often that one feels such acute loss of a friend seldom seen over many years. But receipt of Mark’s email totally altered the day of someone so far away on the other side of the world.

I think I can claim a special privilege with respect to the Routbort Family as I alone of all Jules’ friends and colleagues was present when you and Jules first met. Little did I realise the significance of that moment at the time; maybe you and Jules did, but it was later that I was let into the secret – but not much later. “Man! I’m going to marry that woman!’ – Well, characteristic words something like that.

Jules was a truly great character. He was so genuine and generous and I can’t think of another person that I’ve ever met with more infectious enthusiasm.

I think Professor Philip Bowden in Cambridge was looking for an expert in internal friction to be by my side as I navigated towards my PhD in the same field. He could scarcely have chosen better. It wasn’t long after his arrival in Cambridge that Jules and I became firm friends and Jules was introduced to the 7 St. Barnabas Road Fraternity and joined me as a member of that household of Cavendish Laboratory ‘élites’.

I think I’m right in saying that when Jules and I made our first skiing expedition to the Alps together it was the first Alpine skiing experience for both of us. I had only skied in Scotland previously and I remember that my skiing gear at that time was rudimentary to say the least. However, although Jules might not have been the best skier on the Valluga one can be sure that no one else on the slopes demonstrated more determination and exerted more energy. Furthermore the crazy Englishman with him, inappropriately dressed as a hiker on skis, was clearly not going to be totally eclipsed by the challenging verve of his companion.

It was much the same on the tennis court. Hard fought battles, not necessarily the most elegant, but well worth the effort.

And of course who can ever forget the day of the World Cup soccer final of 1966 in London? But for a few of us that match was overshadowed by another momentous ‘match’ taking place in the heart of Germany!

So many stories of those days come to mind. All of them good; all of them treasured. Of course in the back of my mind I always expected the day to come when we would all meet again. But it wasn’t to be. Anja - please accept my condolences at this sad time. You are not alone in your grief. And it is wonderful that you have a Family that will gather round to support you through the days ahead.

Mike Murray

I was devastated to hear about Jules - I always thought he was indestructable. My deepest sympathies to you and all the family.

I have hundreds of memories of Jules. Perhaps the earliest is when he first came to Cambridge and moved into 7 St. Barnabas Road he convinced that it was OK to wear blue jeans (Levis of course!) on a day to day basis. Plus he encouraged Ray McLenaghan and myself to join him in a beard growing competition. I still have the beard and I still wear jeans!

And that first Christmas in Cambridge he came skiing with myself and Mike Murray to St. Anton. Murray and I drove out from England in my mini van and we picked up Jules in Munich where we stayed in a fantastically clean hotel run by an order of Catholic nuns.

What a man!

PS Not to mention the wedding where Mike, Ray, and I watched the 1966 World Cup Final in a room with 50 or so other people, all of whom, strangely enough, seemed to be supportimg Germany!

Dirck Van Vliet

I knew both Agnes and Jules in the 1964-66 period when there was a “non-hippy” Cavendish Physics Commune at 7 St. Barnabas Rd., Cambridge. I knew that Jules and Agnes were headed back to Argonne, but I rather lost touch with them, unfortunately. While not knowing Jules real well, he struck me as an extremely gentle man. Furthermore, The Chicago Tribune Obituary gives firm testament to his many technical accomplishments. His passing is clearly a great loss to all who knew him.

Geoff Woolhouse

My Deepest Sympathy to all of you and your family. I truly loved Jules as a wonderful man and boss. He was such a pleasure to work with and a terrific person. Due to the journal work, I received e-mails from him daily and they were always humorous and showed his love for his family. He truly loved you all very much and was so proud of his children and grandchildren. It was such a shock to hear of his passing. He will truly be missed and my heart is broken that he is gone. However, as Orlando said, it is a short separation until we see him again when it is our turn.

Diane Kurtz

I am deeply saddened by Jules' passing, and offer my deepest condolences to your family. I started at Argonne in 1998 in the Materials Science Division, and had an office in the corridor next to Jules for many years. He always epitomized the Argonne scientist for me, and our community will miss him sorely.

Stephen Streiffer

I am probably the longest surviving friend and colleague of Jules and although sadly we never collaborated on any scientific programs and never attended each other’s weddings, we exchanged gifts which we long treasured and occasionally socialized at our homes and on the tennis court. From the very beginning Jules and I shared much the same outlook on life: secular humanism, dedication to the scientific enterprise, a love of classical music, and a wariness about the exaggerated claims by some about our ethnic and nationalistic roots.

I met Jules shortly after I arrived in Rockefeller Hall at Cornell from Imperial College, London, in September 1960 to do a post doc with Henri Sack in the Engineering Physics Department. Jules was working on his doctoral program and I recall was busy passing Sack's qualifying open book exams. The EP Course Programs that Henri Sack had implemented at Cornell were probably the world's best as fellow grad student like Ben Snavely, George Smith, Roger Poeppel and Robert Moog (yes! the synthesizer Moog) and many others could testify. Both Jules and I started our serious experimental programs by digging pits. Jules' one in Rockefeller Hall basement later housed his internal friction pendulum isolation cement block, mine was adjacent to the Triga Reactor building to house the #106 Dynamitron ion accelerator. I must remark that Jules' subsequent contribution to science more than compensated for the discrepancy in the magnitude of these two excavations!

In the summer of 61 when my late parents were visiting Jules offered us a ride to West Coast in his Rambler. We had a wonderful time together for ever cemented in my memory despite being accompanied by the parents. After we both left Cornell we met up again at Argonne in the Materials Science Division in 1970. We were in different groups but frequently socialized an commiserated about the sad state of politics. Thank you Jules for befriending me, your image inside me will never fade.

Anthony Taylor

I would like to express my deep grief about the unexpected and untimely death of Jules. Over the decades, we met on the occasion of international Conferences, e.g. the one on Kauai where you were accompanying him.

I will always remember Jules as man possessing such a positive aura and gifted with a wonderful kind of humor.

Klaus-D. Becker

I worked in an office near Jules for many years about 10 years ago. He was always so kind and sweet. He always talked about his beautiful wife, children, and grandchildren. I could tell how much he truly loved his family. He was a good man and it was my pleasure to know him.

Sheila (Jungman) Trznadel

I worked with Jules as part of a committee that reviews applications for postdoctoral fellowships. I first met him last March when I took my current position at Argonne. Right away, I knew that Jules was something special. He had a lot of class and I had great respect for him as a scientist, a mentor and as a person. I will truly miss him.

Tina Henne

I am deeply saddened to hear of Jules passing away. I had the honor to know him in 1987, when I was a postdoc at the Materials Science Division at Argonne. As a young researcher just starting my academic research, Jules gave me the very much needed guidance and greatest help. We were PIs on a major DOE project working on superconductors. I was so impressed with his knowledge in science, experience in research, and his prominent reputation in the research communities. Not only did he give me the best technical supervision, but also personal guidance in life. He was a top scientist, a close collaborator (we published many papers together), a good teacher, and beloved friend. We will all miss him very much.

Donglu Shi

Liebe Tante Agnes, lieber Julia und lieber Mark, mit großer Betroffenheit habe ich vom Tod von Jules erfahren. Ich war geschockt und konnte es gar nicht glauben. Auf diesem Weg möchte ich Euch mein tief empfundenes Mitgefühl ausdrücken. Es ist immer schwer, einen lieben Menschen zu verlieren und ich kann Euren Schmerz gut verstehen. Ich denke immer gerne an mein Jahr in den USA zurück, es ist zwar schon eine Weile her, aber in dieser Zeit hat sich Jules auch sehr um mich gekümmert. Ich wünsche Euch allen viel Kraft und Gottes Segen, diesen schmerzlichen Verlust zu tragen. Auch hoffe ich, dass wir uns demnächst -unter hoffentlich erfreulicheren Umständen - vielleicht mal wieder sehen oder voneinander hören. In Verbundenheit

Martina Eickhorst

I am in a state of shock and disbelief at this terrible news. This makes me very sad as Jules was a kind friend and a brilliant scientist. His death is a great loss to Argonne, DOE and the Nation. I will always remember his great enthusiasm for the work he was doing and the funny stories he shared with me concerning his dog. Please know that all of you are in my thoughts and prayers at this difficult time.

Jim Eberhardt

I have had the pleasure to have known Jules and work with him as an associate for the past 6 years. His was a unique personality. Seemingly gruff and unapproachable on the outside, and yet soft with a warm heart on the inside. He was a little difficult to get to know, but worth the effort to understand his motivations. He would just beam expressions of joy about his family-- especially his grandchildren. His enjoyment of fine wines and trips to California vintners. I loved him and respected the perspective he added to the politics that surrounds the Lab management and the administrative process. He taught me resilience and perseverance in seeking funding and to never let the DOE management get you down. We shared a long car ride out to Fort Wayne, IN early in my career. It was essentially a four-person road show to introduce Navistar Truck R&D to Argonne’s multi-faceted capabilities. We also shared our outlooks while being stranded too many times at Reagan National Airport trying to get home from meetings with our various sponsors.

Jules was a dedicated researcher who loved his work and was passionate about cultivating young minds. Deep within, I think he was always meant to be a teacher. Regardless, he taught many who chose to listen to look at problems a little differently and not to give up so easily when confronted with bureaucratic challenges. I am sorry for your loss and the loss of a fine person we all looked up to.

Liebe Anja, in die Vorfreude auf unser baldiges Wiedersehen in Passau erhielten wir die traurige Nachricht, daß Jules sehr plötzlich verstorben ist, plötzlich ist es sicher gewesen, weil Mark uns e-mailte , es sei eine Lungenembolie gewesen. Wie gut, daß Jules nicht leiden mußte. Liebe Anja, von uns kommt ein tiefes Mitgefühl. Jules war für uns alle ein sehr liebenswerter Mensch, den Du uns durch Deine Heirat nach Amerika geschenkt hast. Wir haben immer seine liebevolle Zuwendung zu Dir, aber auch zu uns deutschen Freunden empfunden. Wir wünschen Dir, daß Du die schönen Erinnerungen lange pflegen kannst und mit Zuversicht in die Zukunft schaust. Vielleicht sehen wir uns im Jahre 2012 in Deutschland, wir haben dann auch 55- jährige Abi-Feier. Mit herzlichen Grüßen, auch an Deine Kinder. In herzlicher Verbundenheit Elisabeth und Jürgen

I along with many others was shocked to hear this sad news. Although I haven't seen much of Jules since moving to Colorado in 2003, we were good friends and frequently played tennis at the Downers Grove Swim and Racquet Club. He was, as you know, a very lively guy and we had many good times together. I remember fondly a number of ski trips with the Landers and others to Vail. Your Dad was the one who kept the place looking tidy. I was the weakest skier and always remember working hard to keep up with the rest. Please give my most sincere sympathies to your Mother. I have always thought of Jules as a true Mensch, in the best meaning of the word and had a tremendous regard and admiration for him. He be missed and long remembered.

I was, and still am, deeply stunned and saddened, by the loss of your father. I had not worked with him recently as closely as I had in previous years but knew that Jules was always around if I needed someone to talk things through. And, whenever I did talk to him the conversation always wound up in lots of crazy laughter. Your father was one of the truly good guys. Deeply compassionate and caring. And in a world where the work of science and engineering often overshadow family and friends, Jules' strong love for your mother and for all of his children and grandchildren (qnd his dog) surrounded and swirled through everything he did. He was so proud of you all! It is for this that I will most remember him.

Renée Nault

Dear Anja and family... the sad news travelled fast. So many friends send us the sad message and like all of these friends, we are also deeply shocked. We can't believe that Jules has left us. He was always so healthy and active. Your last Holiday letter told us of good times and that you are both doing well. We are always impressed with your enthusiasm for life and the happy family gatherings you have in various parts of the world. We always were very fond of Jules. He was one of the stars of the Argonne group and his work was appreciated world-wide! Dear Anja, those memories will sustain you now through these very emotional times. When you are down with sadness, make yourself go back to those happy moments with Jules.

Liebe Anja,lieber Mark, liebe Julia, Euch und Euren Familien möchten wir sagen, dass uns die Nachricht von Jules plötzlichem Tod ungemein traurig werden ließ. Danke, dass Mark uns per E-Mail mitgeteilt hat, dass am 11. März ein Gedenken an Jules im Gebet und in persönlichen Erinnerungen sein wird. Wir werden in Osnabrück in Gedanken bei Euch sein, sowie jetzt und in vielen Stunden.

Liebe Anja, Jules war ein Schatz, neben seinem wissenschaftlichen Schaffensdrang war er unermüdlich im Einsatz für Dich für Eure Kinder und Enkelkinder, für Eure Familien, für alle Freunde und viele Menschen . Er hatte eine große Gabe, sich auch für die kleinen Dinge des Lebens einzubringen. Wir haben durch Euch seine Heimat Kalifornien und Eure Familie in offener, liebenswerter Weise kennengelernt und sind mit Euch traurig, dass Jules nicht mehr bei Euch ist. Glückliche und interessante Stunden in Osnabrück, Washington, New York, Kalifornien, Hagen a.T.W., Berlin bleiben uns in dankbarer Erinnerung.

In Dankbarkeit mit lieben Grüßen Bernd und Betty

Bernhard Bentrup

Ich hatte das Bedürfnis, mit euch persönlich zu sprechen. Ich bin sehr traurig, das Jules nicht mehr bei uns ist. Ich kann das sicherlich besser mündlich ausdrücken als schriftlich. Die Hauptsache ist aber, das ihr wisst, dass wir in Deutschland sehr oft an euch denken. Ich habe diese Tage viel mit Gert, Klaus und Matthias telefoniert..Wir werden in Osnabrück auch am 11.03. einen Gedenkgottesdienst für Jules halten

Eva Hartung

Jules was a great scientist and a great human being, but to me he was also a dear friend with whom I shared many moments of science and working together as associate editors of the APL, but what I cherished more was our chats about life and families and the dreams he and I had to bring the excitement of science to everybody. I will miss our walks to the cafeteria and the lunches we use to have to talk about APL and many other things of life.

Orlando Auciello

We were greatly saddened by the news of Jules' unexpected parting. We remember him as a valued colleague of us both for many years at Argonne and later of David at APL. He was full of zest for life in all its dimensions and a human being of great honor and integrity.

David Price

I met Jules when I was a graduate student at Northwestern. I remember his good advice and great sense of humor with fondness.

Doreen Edwards

Mit grosser Betroffenheit haben wir die traurige Nachricht erfahren. Jules wird in unserer Erinnerung weiter leben. Er war für uns ein sehr guter Freund und Kollege. Dir und den Kindern wünschen wir viel Kraft und alles Gute für die Zukunft. Herzlich gruessen Jochen und Erika PS.: wir denken gern an die Zeit mit Euch in Karlsruhe/Weingarten zurück.

Hansjoachim Matzke

Fred and I are, as are you, completely shocked by the death of your father. We loved Jules and will never forget the many kindnesses he extended to us. Megan and Emily had a most adoring Opa, and I am saddened to the core for all the plans he had to share their future and continue to give them amazing memories, memories which now will not come to fruition. He was so proud of you and Julia and your children. Our deepest sympathy to your mother and to Julia. Sympathy seems like such an non-inclusive word to give to you at this time.

Judy Norten

I have known Jules for all my professional years (~40 years). He was a very dedicated person on anything and everything he did. Great Scientist and very much into promoting science and technology. Very responsive and hard worker. He was the person who volunteered me to ECI. It was great move on his part. It is so shocking. He will be missed for sure by ECI and the materials community. What a sad news.

Ram Darolia

It is hard to find words to express our sorrow for Jules’s death. It is simply too hard to imagine all the memories that must race through your head. We will remember all the fun times we had throughout all the years at Argonne together, our work together in the lab, on home projects, at parties, at the journal office, and on and on. All those memories will live but sadly the time for new fun times has gone. We are glad that Julia and Mark are with you – it is at times like this that one realizes the tremendous strength of a family. You have our deepest sympathy.

John Mundy

We have just received the sad news of the death of our dear Jules. We are really shocked. Just two weeks ago Gerry Lander told us of your planned tour in Italy and we were trying to arrange a vacation there, in the hope to meet you all. During the last decade we have met Jules only occasionally, but still remember with gratitude the period we have spent in Argonne, when he and Agnes made of our staying one of the most beautiful experiences in our life.

We will cherish the memories of the times we spent together and are with you during this time of grief with our thoughts and prayers.

Claudio and Luciana Ronchi

I am the director of Jules' division and was in the process of promoting him to Argonne Fellow, the highest rank for a scientist at Argonne. I wanted to forward this to you so you would have the full extent of your father’s professional accomplishments for any memorial you are preparing

 I was touched by Jules' kindness during my years at Argonne and I both admired him and liked him. I had dinner with him and your mother several times when my family was out of town, and we inevitably ended up looking through endless photo albums of his family. He also thoughtfully forwarded German language children’s books to my kids for their transition into American culture.

Again, most of us are in shock having seen him only a day or two ago – and knowing how vigorous and endlessly energetic he always appeared. He will be greatly missed by all of us.

Don Hillebrand

Jules was my Argonne advisor from 1992-96. My own father passed away while I worked for Jules and he was a great comfort to me during that time. In fact I lost both grandmothers and my Dad during those years and Jules was always so understanding.

I will always have the fondest memories of time spent with him at Argonne, both in the lab, in his office and on the tennis court (where he beat me mercilessly, even though I was 30 years younger). At the time, I never understood how he could eat room temperature yogurt for lunch... (and a banana). I was fortunate enough to be invited over to the house many times and found those occasions to be some of my fondest memories of graduate school. You have our thoughts and prayers during this difficult time.

In 1995, my wife and I took a trip to San Francisco for vacation. When we got back he said, "How was your trip?" I told him we had a wonderful time and loved every minute -- from Napa to SF to Carmel. He practically shouted: "NOW YOU KNOW WHY I'M PROUD TO SAY I'M FROM SAN FRANCISCO!"

Greg Tomlins

I am truly saddened by the sudden passing of your father. I had the pleasure of interacting with Jules first during my time as a graduate student at Argonne around 1990-1993 and then subsequently at many professional meetings. Jules had a great sense of humor and was very forthright with his views. He will be sorely missed. My sincere condolences to you and your family.

Ram Devanathan

I was so sorry to hear of Jules’ sudden death. I knew him over many years at Argonne. He will be missed.

Bill Ragland

My heart is feeling very heavy and my sympathy goes out to you all as you come to grips with this sudden loss. Anja, we haven't talked for years as Jules and I have emailed or seen one another if he was in the Bay Area which has been a while, so I wanted to let you know how important you both have been in my life when I was a graduate student at Northwestern/Argonne and especially when my first husband, Darrel, died. I will always remember Jules' keen mind, jest for lifelong learning and commitment to taking students under his wing and making sure they felt valued, tested and loved. He was a man of great integrity, commitment to scientific truth and insatiable passion. I fondly remember the countless times you had Kristen Persels Constant and me over for meals, playing tennis and then taking me under your wing allowing me to stay in your house after my husband died in MD to complete my thesis/PhD defense at Northwestern with Tom Mason. You two were a big part of the glue that held me together during my great time of loss and sadness.

Jules was such an amazing spirit loving you all -- he beamed and got misty-eyed when he would talk about Anja's tennis achievements and his kids academic and family benchmarks -- so proud and cared so moved by all of you.

I am sending you a very big hug from Oakland, CA and lit a candle yesterday when I heard of Jules' death to honor his life, his family and how he brought so much light and support to my life in my time of great loss and academic intensity.

Kelly Kirkpatrick

Even though he is a distant cousin, I considered Jules my older brother. He is someone I have admired all my life and his passing has affected me greatly. I cannot imagine your sorrow and grief. I want to let you know that you will not be forgotten or out of my thoughts.

With all my heart, my condolences

Jonathan Hyman

I just wanted to tell you, your sister, your mother, your wife, your brother-in-law, your children, and your niece and nephew that the memorial service for your father was a beautiful tribute to him. The love you feel for your father was clear, as was the love you feel for each other. I was well aware of your father's many professional accomplishments, but you all displayed for the world his achievements as a family man. From what I heard at the service yesterday, he would have been proudest of his family yesterday. Thanks for sharing a part of your father with us.
