In Memoria

VESSOT, Robert Frederick Charles Physicist Born April 16, 1930 in Montreal, Canada, Bob was the only child of Robert Charles Ulysses Vessot, and Marguerite Yvonne (Giauque) Vessot. Bob was raised in the Town of Mount Royal, and earned a B.A., M.Sc. and Ph.D. in Physics, from McGill University in Montreal. He served in The Royal Canadian Air Force with N.A.T.O. as Station Communications Officer in Zweibrucken, Germany. In 1956 Bob settled in Cambridge, MA having been recruited by M.I.T. as a post doctorate member of the research staff working on the development of the Hydrogen Maser (Atomic Clock), invented by two Nobel Prize winners at Harvard. It was during this time that he met and married his wife of 59 years, Norma (Wight), another transplant from Montreal to the Boston area. In 1960 he moved his young family to Marblehead and went to work at Varian Associates in Beverly, MA. When Bob elected not to relocate to California upon his company’s acquisition by Hewlett-Packard, Bill Hewlett personally facilitated the move of his entire lab to the Harvard Center for Astrophysics in Cambridge, MA. He worked as a physicist at the Smithsonian Astrophysical Observatory and as an associate of the Harvard College Observatory until his official retirement in 2001, although he continued volunteering with graduate students at the lab until 2015. Over the course of his successful career, Bob was best known for his contributions to the development of the atomic clock based on the maser and its application to the experimental verification of Einstein’s General Theory of Relativity, which he performed with NASA. For this he was awarded the NASA Medal for Exceptional Scientific Achievement in 1978. The 30 atomic clocks built by his group have been used in satellite-tracking stations, in radio telescopes, in research labs in the United States and Europe, by the U.S. Naval Observatory for tracking the Nation’s time, and by Jet Propulsion Labs to guide the Voyager spacecraft to Jupiter, Saturn, and beyond. Bob received many other scientific awards, including the 1993 I.I. Rabi Award of the IEEE, authored numerous publications and owned several patents. Bob loved his work and traveled extensively throughout the world to lecture and attend conferences, often stopping in Switzerland to visit with family on his way home to Marblehead. Bob was a kind and fun-loving man who often used his many talents to help others. He enjoyed nothing more than day sailing and racing his different boats before acquiring a Nonsuch, on which he and Norma cruised for 29 years. In his beloved cellar workshop, he tinkered with motorcycles (which, in his younger years he also raced), antique cars and old marine engines. In this workshop he also produced and repaired parts for old watches and clocks, a hobby he attributed to his Swiss heritage of clock makers. Throughout his life, Bob also enjoyed tennis and skiing, listening to classical music and playing his pianos and reed organ. In his later years, he became a devoted Patriots, Bruins and Red Sox fan. Bob was an active member of the Eastern Yacht Club in Marblehead as well as many professional and social organizations. He is survived by his wife Norma Newman (Wight) Vessot and their daughters, Judy Gardiner and her husband, Joel, Peggy Lyons and her partner, Tim Moran, and Nancy Thorne and her husband, Charlie. Bob also leaves his six grandchildren, Alex and Tory Gardiner, Lindsay and Hannah Lyons, and Ben and Sam Thorne, plus many nieces and nephews and their families in the U.S., Canada and Bermuda. Bob will be greatly missed by his loving family and friends. A private service will be held this summer.

He was made a Fellow of the IEEE in 1980. He received the IEEE Centennial Medal. In 1990 he received the “Aviation Week” LAURELS Award for RF-Wafer Scale Integration. He became a Life-Fellow of the IEEE in 2000. Dr. Lawrence Whicker passed away on June 20, 2018.

It is with the greatest sadness we announce that our dear colleague and friend Jean-Michel Kiat (1956-2018) passed away on the afternoon of Tuesday 13th, 2018 following a month of complications after heart surgery. Jean-Michel will always be remembered in the scientific community as a significant contributor to the ferroelectric community, as crystallographer, and through his precise and useful structural characterizations of various ferroelectric materials using both x-ray (laboratory and synchrotron) and neutron diffraction techniques. Jean-Michel graduated in Electronic Engineering from ISEP (Institut Supérieur d’Electronique de Paris) in 1979 and received his MSc of Physics of Solids from University of Orsay in 1980, his PhD and habilitation in 1988 in Materials Science from University Pierre-et-Marie-Curie. His thesis work was done at Ecole Centrale Paris (a top-ranked French “Grandes Ecole”) in collaboration with the French National Centre of Telecommunication Studies (CNET) on the incommensurate and metastable states in barium sodium niobate and lead orthophosphovanadates of interest for their electrooptic and nonlinear optic applications.
In 1983, he joined the laboratory of Chemistry and Physics of Solids at Ecole Centrale Paris and the French National Centre for Scientific Research (CNRS) as senior scientist. In 1990, he also became Associate Researcher at Laboratoire Léon Brillouin, the French national laboratory of neutron scattering, and took responsibility of the thermal neutrons 4-circles diffractometer (6T2) that he co-developed technically. In 1999, he became Research Director at the CNRS and the first Head of Structures, Properties and Modelling of Solids (SPMS) lab at Ecole Centrale Paris promoting the ferroelectric activity making SPMS one of the main French player in this field. Jean-Michel conducted research on the physics of phase transitions in ferroelectrics including incommensurate phases in ferroelectrics, quantum paraelectrics, relaxors, piezoelectric and morphotropic phase boundary materials and multiferroics in different materials forms (powders, single crystals, thin and thick films, nanoparticles, core-shell structures or more exotic nanostructures such as nanodonuts). He used in situ high resolution x-ray and neutron scattering techniques under external constraints including low and high temperatures, high pressure, or electric-field and his crystallographic expertise for analysing the data using Rietveld refinement or Gram-Charlier expansion analysis for instance. More recently and still very creatively, he started a fruitful research activity on capacitive energy storage and electrocaloric refrigeration. He co-authored over 150 publications with a large number of colleagues from many countries and he supervised more than 20 PhD students, who now have successful careers both in academia and in the industry. He was also involved in applied research by promoting start-ups. In addition, he served the ferroelectric and neutron communities by being involved as member committees and organizer of conferences or schools (EMF International steering Committee, “Ecole et Rencontres Rossat-Mignod”, “Journees de la diffusion neutronique”, …) Jean-Michel also had a passion for Japan where he spent several (short and long) stays and learnt to speak Japanese, fully immersing himself in this country and its people. He was an expert of aikido (7th Dan, Seitaï branch) and he became instructor of this Japanese martial art. We will remember his great scientific skills, his kindness, his modesty, his simplicity and his shyness and occasional cautiousness, as well as the friendly and open scientific atmosphere he created around him. All this will remain an inspiration for us all for a long time to come. Jean-Michel is survived by his two children, Virginie and Sylvain and their mother Aline as well as all the people who knew him in France and in so many other parts of the world, in his work or aikido environment, as well as in his friends and family life. We will all keep a part of him in our memory.

Mustafa Karaman (S’88–M’93) was born in Balıkesir, Turkey in 1964. He received the B.S. degree from the Middle East Technical University, Ankara, Turkey, in 1986, and the M.S. and Ph.D. degrees from Bilkent University, Ankara, Turkey, in 1988 and 1992, respectively, all in electrical and electronics engineering. His PhD work was focused on the use of digital VLSI circuits to beamforming. He was a postdoctoral fellow working with Matt O’Donnell in the Biomedical Ultrasonics Laboratory of the University of Michigan, Ann Arbor, MI, between 1993 and 1994, producing significant work on synthetic aperture imaging for small scale systems. He served in Kırıkkale University, Turkey, between 1994 and 1996. Then, he worked at Başkent University, Ankara, Turkey, between 1996 and 2000 as an associate professor and served in founding the faculty of engineering. In this period, his work focused on aberration correction. He was joined the E.L. Ginzton Laboratory at Stanford University, Stanford, CA, as a visiting faculty member between 2000 and 2002, contributing to the development and implementation of early imaging systems based on CMUTs. Between 2002 and 2013 he worked as a professor in the Department of Electronics Engineering, Işık University, Istanbul, Turkey, during which he collaborated with colleagues at Stanford and Georgia Tech on catheter based 3D imaging CMUT -on-ASIC and CMUT-on-CMOS systems. His last position since 2013 was at Istanbul Technical University. He passed away January 11, 2018. He authored more than 100 papers in refereed journals and conferences. He received the IEEE UFFC Society’s 2002 Outstanding Paper Award as a co-author, and the 1996 H. Tuğaç Foundation Research Award of TUBITAK of Turkey.

Pierre Tournois passed away at his home in Cagnes-sur-mer (France) on March 6th 2017. Pierre is a worldwide recognized pioneer in the field of signal processing, surface acoustic waves (SAW) and optics. His innovations and discoveries had a significant impact on the scientific world: Gires-Tournois Interferometer, Maerfeld-Tournois wave, SAW dispersive delay line, devices for controlling and measuring the time shape of a laser pulse. Furthermore, under his dynamic and enthusiastic management, a large spectrum of innovations were promoted: adaptive antenna for sonars and radars, development of an IRM system, and of course, many new ideas in SAW, signal processing and ultra-fast optics. Pierre was born in Paris on March 26th 1936. He graduated from the ”Ecole Supérieure d’Optique” Paris in 1959. He probably fell into a “signal processing bath” at this place since for the whole duration of his career he developed devices, either digital or analog, in SAW or in optics, for pulse shaping sonar, radar or laser signals. He started his career at the Central Research Laboratory of Thomson CSF. He was immediately noticed by publishing in 1964 the idea of what is known today as the Gires-Tournois Interferometer, shortly after the first experimental demonstration of a pulsed laser. In 1966, he joined the very new sonar department of Thomson CSF in Cagnes (near Nice). There, he was in charge of creating an R&D group for the sonar activity. He organized 2 groups, one in digital technology and the second in analog. Both groups were very successful: the digital group is still famous for their work in adaptive antennas, and the second for their studies in SAW: large timebandwidth dispersive delay lines, SAW convolvers and the Maerfeld Tournois wave. In 1974, he was called to head the sonar department and acted as a pure manager up to 1982. Most of the time, the career of scientists proceeds irreversibly towards management. They start their career as brilliant scientists and as they become older they move to managerial positions. From 1982 to the end, Pierre followed the exact opposite path, from operational manager to technical director to scientist: in 1982, he became technical director (and vice president) of CGR, a subsidiary of Thomson CSF devoted to Medical Imaging (1982-1987). His strong action led to the design of the first MRI system of this company. Then he became the vice president of the Aeronautics Branch of Thomson-CSF, in charge of Research and Development 1988-1999. At that time, acting as a part-time scientist, he renewed his interest for the compression of laser pulses, for which the Gires-Tournois interferometer had been a pioneering invention. Compression had become a crucial problem with the advent of femtosecond pulsed lasers and amplifiers. After introducing several new concepts such as grism compressors, he searched for the Grail of an optically simple and electronically tunable device and found it with acousto-optic interactions. The new device, which is known in the world as the “Dazzler”, its commercial name, rapidly became a workhorse in the ultrafast laser community.
In 1999, he leaved Thales to co-found Fastlite, a small start-up, based on his inventions. Fastlite has evolved into a world leader in ultrafast pulse shaping and characterization of laser signals. The list and dates of prestigious awards he has received bears witness of his remarkable journey from scientist to manager and back. 1971 – BLONDEL’s medal 1973 – Grand Prix de l’Electronique Général FERRIE 2005 – David SARNOFF Award 2006 – Grand Prix des Ingénieurs de l’Année (Engineer of the Year) 2009 – Grand Prix Léon BRILLOUIN de la Société Française d’Optique (French Optical Society grand prize) He is a founding member of the French Academy of Technologies. Pierre is survived by his wife, Jeanne (Nanou), his daughter, Catherine, and his son Pascal who is pursuing his father’s legacy at the head of Fastlite.

Eric, a fine, gracious, gentleman, was born in Alexandria, Egypt and died in Victoria, BC. He was an electrical engineer who loved and was grateful for the life he lived. In May 1948, the day he finished writing his London Matriculation exams, he was arrested. Being Jewish and without citizenship he had no national courts to address and languished in many levels of Farouk’s prisons until 1950 when he was acquitted by the civil courts. Still on the black list he was unable to leave to study in London until November too late to enroll in the chemical engineering degree program to which he had been accepted. He wrote a letter to his father stating that he was wavering somewhat because of his love of mathematics and physics. His father replied “become an engineer” which Eric considered the best advice he ever acquired. In 1955 he completed his degree in Electrical Engineering at Battersea College (now University of London), and began research at IT & T. Wanting to continue his education at the postgraduate level but unable to obtain financial support because of his statelessness, he sought a new homeland. Canada welcomed engineers and provided airfare. The University of Toronto’s offer of a job as a demonstrator enabled him to complete a Masters in Applied Science in 1959. During his time in Toronto he made friends with Peter Peet Silvester who remained a friend and colleague. In 1958 Dr. G.L. (John) d’Ombrain, the chairman of Electrical Engineering at Battersea College during Eric’s undergraduate years, became chairman of Electrical Engineering at McGill. He invited Eric to McGill University, his lifelong anchor. Gerald W. Farnell (PhD 1957) became Eric’s doctoral supervisor (1966 Acoustoelectric Interactions in Cadmium Sulfide) and lifelong research collaborator in pioneering research into Surface Acoustic Waves (SAW). Filters and signal processing devices for applications in communications devices such as televisions and cellular telephones are based on their publications. Eric developed a computer program which became the industry standard for SAW filter designers. His years collaborating with Pierre Belanger and Nick Rumin on Introduction to Circuits with Electronics were some of his most fulfilling and enjoyable. In 1961 Eric obtained Canadian citizenship, a Canadian passport, and a wife, Leonda (Lee). He was elected a Fellow of the IEEE in 1989 and appointed Distinguished Lecturer by its Ultrasonics Society in 1994. He also served the Faculty of Engineering as Associate Dean (Academic) from 1977 to 1985 and made key contributions to curriculum development and making the Engineering Faculty more welcoming for women students. Eric retired from McGill in 1995 and was granted Professor Emeritus in 1998. In Victoria Eric enjoyed his time with Literacy Victoria, Engineering Associates at U Vic, playing bridge with Jack Basuk, and wide access to music. He leaves his wife; sister, Evelyn Moore (Eve and Pony); two nieces, Carole and Susan (Jefferson Davis); many grandnieces, grandnephews, cousins, friend/ colleague, Maier Blostein (Rhoda), and Norma Farnell. Many thanks to the kind caring medical staff at VGH, 6 B South. At Eric’s request there will be no funeral. Source: Montreal Gazette and the (Victoria, BC) Times Colonist (November 18, 2017)

Professor David Owen Cosgrove, a pioneer in the clinical applications of ultrasound technologies, passed away on Tuesday the 16th of May 2017, at St. Raphael’s Hospice, North Cheam, London, after a short battle with cancer. Professor Cosgrove was born in Nairobi, Kenya in 1938. He obtained a BA in physiology from Oxford (1961) and subsequently qualified in medicine from St George’s Hospital Medical School in London. In 1977, after working in a number of hospitals in London and Nairobi, he became a consultant in Nuclear Medicine and Ultrasound in the Royal Marsden Hospital in Sutton. In 1993 David moved to the Hammersmith Hospital, which later became a part of the Imperial College School of Medicine, and was awarded a personal chair as Professor of Clinical Ultrasound. David officially retired in 2004, became an Emeritus Professor at Imperial College as well as a Senior Research Investigator at King’s College Hospital, and remained extremely active in the field. The ensuing list of honours and accomplishments in David’s successful career are extensive, suffice to say that David’s contributions were immense. David published more than 200 peer reviewed research articles and 30 teaching books/book chapters over his career. He held honorary memberships in many national and regional ultrasound societies and was one of the world’s most sought after invited speakers at international conferences, including the 2012 IEEE International Ultrasonics Symposium (IUS) where, as an invited clinical keynote speaker, he presented insights into the clinical needs for new ultrasound technologies. David had a tremendous curiosity and possessed an in-depth understanding of the physics and engineering of ultrasound. In this regard, he dedicated himself throughout his professional career to driving clinical applications of new ultrasound technologies, as well as linking ultrasound engineers and physicists with clinicians to address problems of real clinical need. He was at the forefront of clinical advances in radiological ultrasound technologies, including microbubble contrast-enhanced ultrasound and ultrasound elastography. He was a vice president and founding member of the International Contrast Ultrasound Society (ICUS), advisor to NICE and various grant giving authorities, and a member of many editorial boards of journals and expert working groups. He was closely involved in the two key and highly interdisciplinary international conferences on Contrast Enhanced Ultrasound; he co-organised the European Symposium on Ultrasound Contrast Imaging held annually in Rotterdam, and was an invited faculty speaker for the Bubble Conference held annually in Chicago for many years. He was also an active and highly valued contributor to the weekly engineering and physics ultrasound group meetings held jointly between Imperial College London and King’s College London. Another particularly important contribution, which continued throughout his career and beyond his retirement, was his role in advising industry. With his unique insights in both clinical needs and ultrasound physics and engineering, his advice for product improvement was invaluable, and in return he was able to work with the very latest and novel products for clinical evaluation and research. Even in his very early days in The Royal Marsden Hospital he advised on the development of one of the early commercial phased array abdominal ultrasound scanners by EMI, a company which also developed the x-ray CT scanner from the Nobel Prize winning invention that Godfrey Hounsfield had made while working there. Through his diplomacy and integrity he was able to engage simultaneously with many companies to continuously improve technologies for real clinical needs and ultimately to improve patient care. David’s collaboration with the Acuson company in the 80s and 90s provides one notable example of his contributions. David was the first person in Europe to be approached by the company to evaluate the Acuson 128 system, the first high-resolution, computer-controlled ultrasound system, and to advise on its suitability for Europe. David was excited about the great improvement in image quality and immediately identified several new clinical applications. David also gave clear, concise feedback on many problems with the system. Thus began a multi-year collaboration and friendship during which he gave valuable information about clinical opportunities which led to further advances in the system. For instance, he was an early advocate for ultrasound breast imaging and motivated the development of new transducers and specialized color Doppler software for the breast. When the Sequoia ultrasound system was under development, Acuson chose David as their international “Guru” to guide the development process for Europe and to evaluate advanced applications. David began influencing and testing the system years before its commercial release. In the early days of contrast enhanced ultrasound, David raised concerns about motion artefacts associated with the pulse-inversion method. His advice motivated the development of Acuson’s novel contrast imaging technology which was considered a great technical advance for imaging contrast agents. David was generous with his keen advice for everyone who worked to advance diagnostic ultrasound. A giant of the medical ultrasound world has passed away. He was unique in so many ways and will be an inspiration to generations of ultrasound practitioners, physicists and engineers across the world. He was truly one of a kind in everything he did and in every way that he was. David will be dearly missed.

August 13, 1936 – September 29, 2017 On Friday, September 29, 2017, emeritus Professor T.W.J.M. (Ted) Janssen passed away at the age of 81 years. Ted Janssen was appointed associate professor at Radboud University in 1972, extra- ordinary professor in Utrecht in 1993 and full professor of theoretical physics at Radboud University in 1994. With the latter appointment he has strongly contributed to shaping the new group of Theoretical Condensed Matter, part of the Research Institute for Molecules and Materials (IMM) of the Faculty of Science. Ted obtained his PhD degree in 1968 from Nijmegen on ’Crystallographic Groups in Space and Time’ as first PhD student of prof. Aloysio Janner, with whom he subsequently collaborated very fruitfully during his whole career. During that career he also had many guest professorships, such as in Leuven, Dijon, Lausanne, Paris, Nagoya and Sendai. Together with Aloysio Janner he was one of the founders of the higher dimensional superspace approach in crystal structure analysis for the description of quasiperiodic crystals and modulated structures. For this work he received in 1988 the Aminoff prize of the Royal Swedish Academy of Science (with P.M. de Wolff and A.G.M. Janner) and in 2004 the Ewald prize of the International Union of Crystallography (with Janner), the most prestigious prizes in crystallography. These achievements were merit of his unique talent, combining a deep knowledge of physics with a rigorous mathematical approach. Their theoretical description of the structure and symmetry of incommensurate crystals using higher dimensional superspace groups also included the quasi- crystals that were discovered in 1982 by Schechtman, who received the Chemistry Nobel prize for this in 2011. The Swedish Academy of Sciences explicitly mentioned their work at this occasion. With his two famous papers “Crystallography of quasi-crystals” (T. Janssen, Acta Cryst. A42, 261-271, 1986) and “Aperiodic crystals: a contradictio in terminis?” (T. Janssen, Phys. Rep. 168, 55-113, 1988) Ted made a major mathematical contribution to this field. However, apart from being an excellent mathematical physicist, Ted was known as a very modest and pleasant colleague and friend. Already from his early years Ted also developed a deep appreciation for literature and music, in addition to visual arts, ballet and architecture. The enjoyment of the arts was essential to him, he called it vital components of life. He started playing the piano, harpsichord and cello in his early twenties, which brought him great joy during his whole life. Ted’s work on crystallographic symmetry was a beautiful combination of his passion for art as well as mathematics. Ted has also actively contributed to education with many beautiful courses of quantum mechanics and mathematical physics and with his great talent in explaining complex problems in simple words to students as well as colleagues. With his research he has strengthened the international scientific reputation of physics in Nijmegen, for which the university is very grateful. He will be missed. Theo Rasing, Radboud University
