John David Jackson (January 19, 1925 – May 20, 2016) was a Canadian–American physics professor emeritus at the University of California, Berkeley and a faculty senior scientist emeritus at Lawrence Berkeley National Laboratory. A theoretical physicist, he was a member of the National Academy of Sciences, and is well known for numerous publications and summer-school lectures in nuclear and particle physics, as well as his widely-used graduate text on classical electrodynamics. The book is notorious for the difficulty of its problems, and its tendency to treat non-obvious conclusions as self-evident. Jackson's high standards and admonitory vocabulary are the subject of an amusing memorial volume by his son Ian Jackson.
Born in London, Ontario, Canada, Jackson attended the University of Western Ontario, receiving a B.Sc. in honors physics and mathematics in 1946. He went on to graduate study at MIT, where he worked under Victor Frederick Weisskopf, completing his Ph.D. thesis in 1949.
Jackson held academic appointments successively at McGill University, thanks to Philip Russell Wallace, a prominent Canadian theoretical physicist, (January 1950 – 1957); then the University of Illinois at Urbana–Champaign (1957–1967); and finally the University of California, Berkeley (1967–). At McGill, he was Assistant and Associate Professor of Mathematics; at Illinois and Berkeley, he was in the Physics Departments. At the latter, he held appointments on campus and at the Lawrence Berkeley National Laboratory. After retiring from teaching in 1993, he continued to be active at LBNL.
McGill and Princeton
At McGill in the 1950s, in addition to appreciable teaching, Jackson found time for research on atomic processes and nuclear reactions at intermediate energies and the beginnings of his book on classical electricity and magnetism.
While on leave at Princeton University, he found a fruitful collaboration with Sam Treiman and H. W. Wyld on weak interactions, particularly the various observable decay correlations in allowed nuclear beta decay involving the electron's momentum, its spin, the neutrino's momentum, and the nuclear spin that provide information about parity conservation or non-conservation and time reversal conservation or not. He also published an early paper on the then recently discovered muon-catalyzed fusion of hydrogen isotopes.
Illinois (1957–1967) and CERN (1963–64)
While at the University of Illinois (1957–1967) Jackson initially continued work on weak interactions as well as strange particle interactions at low energy with Wyld and others. On sabbatical leave at CERN in 1963–64, he collaborated with Kurt Gottfried on production and decay of unstable resonances in high-energy hadronic collisions. They introduced the use of the density matrix to connect production mechanisms to the decay patterns and described the influence of competing processes ("absorption") on the reactions.
During this period Jackson lectured at three summer schools—on dispersion relations at the first Scottish Universities Summer School in Physics, 1960; on weak interactions at the Brandeis Summer Institute, 1962; and on particle and polarization decay distributions at the Summer School of Theoretical Physics, Les Houches, 1965. He also published three books, one on particle physics, based on lectures at the Canadian Summer School in Edmonton and Jasper, 1957; the second, a small book on mathematics for quantum mechanics (1962), and the third, also in 1962, the first edition of his text on classical electrodynamics.
Moving to Berkeley in 1967, Jackson taught on campus, did his research at LBNL, and served in administrative positions at both (Chair, UCB Physics Department, 1978–1981; Head, LBNL Physics Division, January 1982 – June 1984). In the formative years of the ill-fated Superconducting Super Collider project, he served as deputy director of operations of the SSC Central Design Group that did the R&D culminating on the 20 TeV design accepted by President Reagan in 1987.
In the 1960s and 1970s his research alone and with students focused in journal publications and conference papers on models of high energy processes, radiative and resolution corrections for resonances in electron–positron annihilation, spin-flip synchrotron radiation and the polarization of electrons in a storage ring, and, after November 1974, the spectroscopy of the charm–anticharm particles. In 1973, he lectured again at the Scottish Universities Summer School, on hadronic interactions at high energies, and in 1976 at the SLAC Summer Institute, on charmonium spectroscopy. In 1973–74 he ran the nascent theory group at Fermilab and co-edited the proceedings of the 1973 "Rochester" Conference.
In January 1977 Jackson began a 17-year stint as Editor of Annual Review of Nuclear and Particle Science. In much of the 1980s he was involved with many others in the high-energy physics community in activities aimed at the next step up in accelerators. Then in 1983 he became active in the R&D for the SSC, and on the program advisory committee for the SSC Laboratory, when it began in Texas in 1988.
Jackson retired from teaching in May 1995, but retained his connection with LBNL. In the 1990s and beyond his time was increasingly devoted to semi-historical talks and publications on a variety of topics, with a foray into refuting suggestions that cancer may be caused by environmental radiation stemming from ubiquitous electronics use. Noteworthy are a continuing series of papers in the American Journal of Physics on diverse topics in electromagnetism, including rebuttals of mistaken ideas. History of physics publications include the historical roots of gauge invariance, examples of the misattribution of discoveries in physics, and the editing of a sequel to R. T. Birge's history of the Berkeley Physics Department.
Among his students at McGill, Hubert Reeves, a Master's student, went on to international prominence as an astrophysicist in France. John T. Donohue (now in Bordeaux, France) and Gordon L. Kane (University of Michigan) stand out among his Ph.D. students at Illinois. The Berkeley trio, Bob Cahn (LBNL), Rick Field (University of Florida), and Chris Quigg (Fermilab), are prominent particle theorists.
Memberships and honors
Jackson was a Fellow of the American Physical Society, a Member of the American Academy of Arts and Sciences, and a Member of the National Academy of Sciences. In 1956, he was awarded a Guggenheim Fellowship. In 1989, he received an Honorary D. Sc. from his alma mater, the University of Western Ontario. In 2009, in recognition of his own contributions to classroom teaching and his influential textbook, the American Association of Physics Teachers created the "J. D. Jackson Award for Excellence in Graduate Education," with the first award in February 2010 to Eugene Commins.
