THOMAS A. TOMBRELLO (1936 -2014) INTERVIEWED BY HEIDI ASPATURIAN December 26 – 31, 2010 Photo by Robert Paz ARCHIVES CALIFORNIA INSTITUTE OF TECHNOLOGY Pasadena, California Subject area Physics, nuclear physics, astrophysics, national security Abstract Interview in nine sessions (December 26–December 31, 2010) with Thomas A. Tombrello, the Robert H. Goddard Professor of Physics, Caltech. Each session is organized around a central topic or theme: (1) early years through college, (2) fifty-year career overview, (3) undergraduate students, (4) Kellogg Radiation Laboratory years, (5) work with Schlumberger research laboratory, (6) Caltech people and personalities, (7) work with national weapons laboratories, (8) ten- year tenure (1998–2008) as chair of Caltech’s Division of Physics, Mathematics and Astronomy, and (9) graduate students and miscellaneous topics. Tombrello opens with his family history, youth, early life, and education, primarily in Texas and Alabama, and his undergraduate (BA 1958) and graduate (PhD 1961) years at Rice Institute. He talks at length about his years in Caltech’s Kellogg Radiation Laboratory, including his research into nuclear physics, materials science, and applied physics, and about the science, culture, people, personalities, politics, and economics of Kellogg and the Division of Physics, http://resolver.caltech.edu/CaltechOH:OH_Tombrello_T Mathematics and Astronomy (PMA) over fifty years. There is extensive discussion of his mentoring work with Caltech undergraduate and graduate students, including his innovative undergraduate course Physics 11 and his perspectives on student life at Caltech. Of particular note is the discussion of his relationship with S. E. Koonin, who went from being Tombrello’s undergraduate advisee to his provost. Tombrello provides a wide-ranging, in-depth look at his ten years as division chair of PMA, covering research, recruitment, fundraising, collegial relationships within and beyond the division and with JPL, and the evolution of PMA under his oversight. He talks about his involvement in the design and construction of the Cahill Center for Astrophysics (dedicated in 2009) and the Thirty Meter Telescope (TMT) project. He describes his interactions with five decades of Caltech presidents and provosts, institute trustees, and various donors. Tombrello recaps his two years as research director at Schlumberger research and his several decades of consulting work on weapons, national security, energy, and climate change issues at Los Alamos and Lawrence Livermore National Laboratories. He talks about his foray into earthquake prediction research, his research collaborations in China, his years as Caltech’s technology assessment officer, and the emergence of entrepreneurism at Caltech in the 1990s. Anecdotes and recollections of such notable Caltech figures as R. Bacher, J. Benton, H. Brown, L. DuBridge, R. Feynman, W. A. Fowler, M. Gell-Mann, B. Kamb, A. Lange, C. Lauritsen, T. Lauritsen, R. Leighton, C. Patterson, R. Sharp, and F. Zwicky are also part of this oral history. Administrative information Access The interview is partially restricted.

Heidi and I sat in my office during this quiet period and talked and drank tea with little prior planning of the direction these interviews might take. By way of explanation of their eclectic contents, it is like history itself in that a chance comment would lead us down unexpected paths. I’m sure if we were to do it again, the trajectory of the interviews might be different, and other topics that are not addressed here would have appeared. Even with thirteen hours of interviews, one does not expect to cover an entire life and career. In correcting the written text of these interviews, I have resisted the temptation to complete stories using details about what has happened in the year since they took place. For example, Nathan Myhrvold did indeed make a lot of money from the Caltech patent I sold him (Session 9). What you have here is, therefore, a snapshot of my life and career taken at the end of 2010. Throughout this oral history, I have tried to be candid and to present my point of view completely without varnish. From the perspective of those I mention, things may well have looked different. Virtually all of the people I have known have been decent and honorable people. Where I have been negative, I definitely meant to be—take that as you will. My ideal is Horton, my favorite character in all of fiction. “I meant what I said and I said what I meant.” 1 Finally, I have to acknowledge that none of this would have occurred without the encouragement of my colleague of many years, Jenijoy La Belle. She is a lady of charm, wit, and style. Obviously, my interviewer, Heidi Aspaturian, is quite extraordinary—not only as an interviewer but also as an editor. Pulling together thirteen hours of conversation and putting them in coherent form are things that only a talented and dedicated individual could accomplish. Thomas A.
