(PO80).  Applied physicist Robert “Bob” Buhrman, M.S. ’69, Ph.D. ’73, the John Edson Sweet Memorial Professor of Engineering Emeritus and Cornell’s second senior vice provost for research, and vice president for technology transfer and intellectual property, who helped expand emerging science and engineering programs, and obtain funding for research, died April 13 in Rochester, New York. He was 75.

“Bob Buhrman was a visionary and effective leader for more than 50 years at Cornell, helping to organize numerous research centers, serving as director of Applied and Engineering Physics and as vice provost for research,” said Dan Ralph, Ph.D. ’93, the F.R. Newman Professor of Physics in the College of Arts and Sciences (A&S). “He was a valued mentor to countless students and young faculty, providing wisdom on how to succeed in science and engineering.”

Robert Alan Buhrman was born in Waynesboro, Pennsylvania on April 24, 1945, and he grew up on a small farm in Smithsburg, Maryland. He earned a bachelor’s degree in engineering physics at Johns Hopkins University in 1967 and his master’s and doctoral degrees in applied physics from Cornell.
 
Buhrman joined the Cornell faculty in 1973 as an assistant professor in the School of Applied and Engineering Physics. He became an associate professor in 1978 and a professor in 1983. He was named the John Edson Sweet Professor of Engineering in 1993.

Buhrman served as the associate director of the National Research and Resource Facility for Submicron Structures from 1980-83 and director of the School of Applied and Engineering Physics from 1988-98. He was the first director of Cornell’s Center for Nanoscale Systems in Information Technologies.

Buhrman led his field in developing methods to reorient nanoscale magnets (electrons) to make magnetic memories faster and more efficient. His innovations enabled spin-transfer-torque magnetic random-access memory, now in production at leading semiconductor foundries. His work was the first to demonstrate magnetic switching in a multilayer device driven by spin-transfer torque, and he also discovered a giant spin Hall effect in heavy metals, which can enable even more efficient magnetic switching.

He was a remarkable person, an outstanding scientist, teacher and organizer of science.

James Wong

October 9, 1927 to October 4, 2020
Dr. James Wong

(PO77). WONG, Dr. James From Wayland, MA, passed away peacefully on October 4, 2020 at the age of 92 surrounded by his family. He is survived by his beloved wife of 65 years, Lorinda (née Yung), and their seven children: Lesley Wong and husband Chris Grande (deceased) of Lexington, KY, Corinne Wong and husband Steve Wilson of San Rafael, CA, Marcy Zenobi-Wong and husband Renato Zenobi from Zürich Switzerland, Terence Wong and wife Amy Sullivan of Wayland, MA, Jamie Wong from Montreal, Canada, Jessie Harlin and husband Brian Harlin of New York, NY, and Lori Wong and husband Rick Miller of Los Angeles, CA. He was a loving grandfather to his 17 grandchildren who were a constant source of great pride and joy for him. James was born in New York City Chinatown on October 9, 1927, the youngest of eight children. Following his older brothers' lead, he entered MIT in 1944 and discovered his calling for engineering, earning his PhD in Material Science in 1955. In 1962, he founded Supercon, Inc., to which he remained dedicated, going to work every day until March 2020.

A renowned expert in the field of superconducting materials, Dr. Wong's passion for inventing led to numerous patents that advanced the manufacturing of specialty metal alloys. In 2011, he received the prestigious IEEE Award for Continuing and Significant Contributions in the Field of Applied Superconductivity for his pioneering work in producing commercial grade superconducting cables and conductors. The award has since been renamed "IEEE Dr. James Wong Award for Continuing and Significant Contributions to Applied Superconductor Materials Technology." James was dedicated to his wife Lorinda and their family. James had a green thumb and spent his free time tending his vegetable garden and flowering plants. The yearly tomato, corn, and chestnut harvests impressed everyone who had the pleasure of sharing this bounty. He was also a great lover of the ocean and spent many holidays fishing and clamming with his family. There was no food he loved better than a platter of fried clams.

Private services were held at the Lakeview Cemetery in Wayland. In lieu of flowers, gifts may be made to MIT for the Class of 1948 Student Financial Aid Fund in memory of James Wong '48. Checks may be made payable to MIT and mailed to: Memorial Gifts Office; 600 Memorial Drive, W98-500; Cambridge, MA 02139.

(PO76).  Rafael Navarro was born in the middle of the last century in Teruel, a small city south of Zaragoza, northern Spain. His passion for science brought him to the University of Zaragoza, first as a student and later as a teacher and researcher. He was a Professor with strong convictions about how the University should evolve. He was always faithful to these ideas, taking a step forward and trying to put them into practice from numerous management positions at all levels: Director of the Department of Materials Science and Technology and Fluids, Director of the former Engineering School, member of the Governing Council and the University Senate, and, more recently, as an Academician at the Zaragoza Royal Academy of Sciences.

His research career began in the Low Temperature Physics group, together with Professor Domingo González and with the group of Professor Jos De Jongh, at the University of Leiden, where he received his Ph.D. in the field of magnetism. Years later he was instrumental towards the establishment of the Institute of Materials Science of Aragon (CSIC-University of Zaragoza), where he started a research group in the field of superconductivity, with initial activity linked to the development of advanced processing and characterization methods for low and high Tc superconducting materials, as well as cryogenic instrumentation applications. The development of mechanical and laser texturing methods of high Tc superconductors, as well as the interpretation of their physical properties, are among his outstanding contributions to the  Superconductivity and Materials Science disciplines. He was a foremost, recognized expert in the knowledge of the mechanisms that explain the behaviour of materials and showed great versatility to approach the development of applications, starting from a sound theoretical point of view. Even in this last year, while struggling with his illness, he was intensely involved in contributing to the fundamental and practical understanding of the processes that drive the interaction of power lasers with the surface of materials.

Rafael, Rafa for the people who have come across him, was, above all, a close person of superb human quality. Outside of his professional duties, he had a great interest in culture, cinema and mountain hiking.  He was very special, someone that always received you warmly, would listen to you and with whom it was possible to have transcendental conversations about life. In essence, those of us who were fortunate enough to interact with Rafa, are profoundly influenced by his wisdom, tolerance and great human qualities. These have helped improve our professional and personal character for the better.

Great friend and colleague, you will remain in our memories, we will always miss you.

Alvin Tollestrup

March 22, 1924 to February 9, 2020
Alvin Tollestrup 2018

February 25, 2020 (PO71).  Award-winning engineer and physicist Alvin Tollestrup, who played an instrumental role in developing the Tevatron as the world’s leading high-energy physics accelerator at Fermi National Accelerator Laboratory and founding member of the Collider Detector at Fermilab collaboration, died on Feb. 9 of cancer. He was 95.

Tollestrup led the pioneering work of designing and testing 1,000 superconducting magnets used in the Tevatron, which operated from 1983 until 2011 and for 25 years was the world’s most powerful particle collider. This was the first large-scale application of superconductivity worldwide.

“Alvin’s impact on the laboratory and on high-energy physics was just exceptional, and the development of technology with regard to the superconducting magnets had a tremendous impact on accelerators,” said Fermilab senior scientist emeritus Herman White. “All who knew him, socially and professionally, found him to be engaging, thoughtful and someone with a long, important history of working in the research community and here at Fermilab.”

The Tevatron led to the discovery of two fundamental particles — the top quark and the tau neutrino. The top quark, discovered in 1995, was the last undiscovered particle of the six-member quark family that explains the composition of protons, neutrons and other particles. Scientists worldwide had sought the top quark since the discovery of the bottom quark at Fermilab in 1977. The discovery of the tau neutrino with the Tevatron accelerator followed in 2000.

Tollestrup was born March 22, 1924, in Los Angeles, California. He received his bachelor’s degree in engineering from the University of Utah in 1944. After service in the U.S. Navy, he entered graduate school at the California Institute of Technology, where he earned his Ph.D. in physics in 1950. His doctoral adviser was William A. Fowler, who shared the 1983 Nobel Prize in physics. Tollestrup then took a position at Caltech to build the electron synchrotron, a type of particle accelerator. At the time it was the highest-energy synchrotron in the world, starting at 500 million electronvolts, or MeV, finally reaching 1,300 MeV.

He joined the Caltech faculty as an assistant professor of physics in 1953. While on sabbatical at CERN, the European particle physics laboratory, from 1957-58, he helped plan and execute the first experiments on the lab’s 600-MeV cyclotron particle accelerator. The work led to the first observations of the electron decay mode of the pion (a subatomic particle consisting of up and down quarks and antiquarks). He became an associate professor at Caltech in 1958 and a full professor in 1962.

Tollestrup arrived at Fermilab in July 1975 on another sabbatical, intending to stay only six months. He ended up stretching the sabbatical to two years, during which time he worked on superconducting accelerator technology.

He joined the Fermilab staff following his sabbatical and in 1978 became head of the newly created Collider Detector Facility. He later became a founding member of the CDF collaboration, serving as its co-spokesperson from its inception in 1983 until 1992. He was instrumental in organizing the CDF collaboration, which initially consisted of 13 institutions and 87 physicists from the United States, Italy and Japan. His recruiting strategy included producing an “Uncle Alvin Wants You!” poster (see page 5).

During the 1990s Tollestrup also became a founding member of the Neutrino Factory and Muon Collider collaboration, which today is known as the Muon Accelerator Program. MAP is devoted to developing and testing the demanding technologies and innovative concepts needed to discover and explore exciting new regions of fundamental physics.

In 2009, along with Florida State University’s David Larbalestier, Tollestrup successfully launched and led the Very High Field Superconducting Magnet Collaboration. Its purpose was to study the applications of high-temperature superconductors to accelerator superconducting magnets.

After only two years and $4 million in funding, the collaboration significantly increased the current density of a bismuth-based superconducting material that would be needed for the potential next-generation of accelerators and new cutting-edge technologies for applications in industry and medicine.

Photo: Janine TollestrupTollestrup received many honors during his career, including the National Medal of Technology — the nation’s highest honor for technological achievement — and election to the National Academy of Sciences. Tollestrup received the Robert R. Wilson Prize of the American Physical Society for Achievement in the Physics of Particle Accelerators in recognition of his contributions to the development of the Tevatron’s superconducting magnets. Other honors include Caltech’s Distinguished Alumni Award and the 2011 IEEE Award for Continuing and Significant Contributions in the Field of Applied Superconductivity from the Institute of Electrical and Electronics Engineers Council on Superconductivity for significant and sustained contributions in the field of large-scale applications of superconductivity.

Well-known for nurturing students and young scientists, he also is the namesake of the Tollestrup Award for Postdoctoral Research, which the Universities Research Association Inc. has presented annually since 2003. The award recognizes outstanding work conducted by a postdoctoral researcher at Fermilab or in collaboration with Fermilab scientists.

“While the research community is well aware of Alvin’s scientific contributions, I think one of the greatest legacies he leaves is his devotion to nurturing young people in the field,” said Brookhaven National Laboratory scientist Mark Palmer, who worked with Tollestrup in the Muon Accelerator Program. “Numerous young researchers were beneficiaries of his patience and incisive approach to problem-solving as he mentored them.”

Archie MacRobert Campbell

May 3, 1940 to November 21, 2019
Photo circa 2018
December 02, 2019 (PO70).  It is with great sadness that we inform the scientific and cryogenic communities that Professor Archie Campbell died on Thursday, 21 November 2019. Archie passed away peacefully at home after a short illness. He is survived by his wife, Anne, his children Frances, Emily, and Diarmid, and his eight grandchildren.
 
Archie was appointed a University Lecturer in the Department of Engineering in 1974 and was a Professor of Electromagnetism at the University of Cambridge, also serving the University as Pro-Proctor from 1985 to 1986, and then Proctor from 1986 to 1987. He had been a Fellow of Christ’s College since 1966 and celebrated 50 years in this role three years ago. 
 
Archie had a long and distinguished career in his field, spanning over 40 years.  He pioneered the so-called "Campbell technique" for investigating the penetration of flux in bulk superconductors and, together with late Prof. Jan Evetts, authored in 1972 the subject-defining monograph “Flux pinning in Type II superconductors” (Adv. Phys. 21, 199, 1972).  Upon his retirement from the Department of Engineering in September 2007, the ‘Campbell Conference’ was held to recognize his significant contributions to studies of flux pinning in Type II superconductors, ac losses, and understanding of the critical state in superconducting materials. Archie remained an active member of the Cambridge Bulk Superconductivity Research Group and the Department of Engineering following his retirement and continued to play a key role in the development and understanding of applied superconductivity right up to his death. He was a much-loved and highly regarded colleague and collaborator, and his loss will be felt by the entire international superconductivity community.

David Cardwell
 
Archie Campbell was one of the few exceptionally knowledgeable and globally respected colleagues in the field of applied superconductivity with deep insight in all aspects of flux pinning in superconductors, low Tc as well as high Tc. My memory goes back to our first encounter during the 11th International Conference on Low Temperature Physics, St. Andrews, 1968, and continues with our International Discussion Meeting on Flux Pinning in Superconductors in 1974 (Sonnenberg, Germany), followed thereafter by a larger number of joint Europe-Japan-US workshops. Archie always contributed creative, often unconventional and novel ideas to these discussion workshops. Now, after his passing, he leaves an enormous gap, which is difficult to bridge.

Francesco Negrini

November 18, 1940 to August 20, 2019

May 4, 2020 (PO74).  Prof. Francesco Negrini, who was full professor of Electrotechnics at the University of Bologna, Italy, from 1986 to 2010, passed away on August 20, 2019.

Prof. Negrini’s research interests have focused on the Electrodynamics of continuous media, Applied magnetohydrodynamics, Applied superconductivity and Magnet Technology. He contributed to these sectors with experimental activities, theoretical investigations and numerical modeling studies.

Two research groups stemmed from his research activities at the University of Bologna: one on Magnet Technology and Applied Superconductivity, and the other on Magnetohydrodynamics and Plasma Engineering.

Professor Negrini led the Italian CNR Project “Superconducting and Cryogenic Technology”, to develop a 52 MJ superconducting saddle magnet for MHD applications. He continuously served the community by organizing and chairing eight international conferences. He held conferences, seminars and Invited Lectures at public and private Universities and Research Institutes in Japan, United States, Russia, China and Europe.

  • On May 26, 2005 he was awarded in Moscow with the "ILG-MHD Faraday Prize" with the following citation: “For outstanding achievements in Magnetohydrodynamics as an Academic and Research Leader of the University of Bologna, for creation of the school on MHD Science and Technology which is a Center of Excellence in Europe and in the world, for contributions in fostering International Cooperation through Distinguished Activities in Europe, the United States, Russia and Japan, for the pioneering development of MHD Retrofitting of existing Power Stations, superconducting MHD magnets and Essential Activity as the Architect of the Italian Program on MHD Power Generation, for his Leadership Contributions to the International Liaison Group on MHD Electric Power Generation.” 

  • On September 19, 2005, at the International Magnet Technology Conference, MT-19, in Genova, Italy, he was awarded the "Special Award for Magnet Technology and Large Scale Superconductivity in Italy" with the following citation: “For his leadership of the Superconducting MHD project in Italy and for his constant pursuing of superconductivity for power applications”.

Prof. Negrini played a prime role in advancing Applied Superconductivity in Italy. He put great enthusiasm in his research and always paid great attention at involving young people in this field. His colleagues and friends at the University of Bologna are very indebted to him for his vision and for his continuous support and encouragement.

John Robert Schrieffer

May 31, 1931 to July 27, 2019

August 7, 2019 (PO69).  John Robert Schrieffer, who along with John Bardeen and Leon Cooper shared the 1972 Nobel Prize in Physics for the BCS theory, passed away on July 27, 2019.

In an account prepared by the American Physical Society, an important idea came to Dr. Schrieffer while riding the New York City subway to a physics meeting early in 1957.  He realized that all Cooper Pairs in a superconductor could be described by just one of the “wave functions” that characterize quantum mechanics. At that time Schrieffer was a graduate student of John Bardeen.

The three protagonists of BCS then blended all of their ideas creating a complete theory.  Their work was submitted for publication to the Physical Review, where it appeared in December 1957 under the straightforward title “Theory of Superconductivity.”

Dr. Schrieffer received his undergraduate degree from MIT and his doctorate from the University of Illinois in 1957.  He did post-docs at the University of Birmingham and at the Niels Bohr Institute.

Schrieffer was on faculty at the University of Chicago, the University of Illinois, and the University of Pennsylvania.  In 1980, he joined the University of California at Santa Barbara as director of the Institute for Theoretical Physics.  In 1992, he joined the National High Magnetic Field Laboratory at Florida State University where he was Chief Scientist and retired from that position in 2006.
