Robert G. Chambers was a British solid-state physicist whose experiments on the electronic properties of metals and the Aharonov–Bohm effect helped establish the physical significance of magnetic vector potentials in quantum mechanics. He was also a senior academic leader at the University of Bristol and received the Royal Society’s Hughes Medal in 1994.
Background
Robert G. Chambers was born in 1924 and became known professionally as Bob Chambers. His early scientific career included work as an experimental officer at the Tank Armament Research Establishment and at the Electrical Research Association before he returned to Cambridge for advanced research. He later made Bristol the principal institutional setting of his scientific and academic life, remaining closely associated with the University of Bristol until his death in Southmead Hospital on 17 December 2016 following complications from a fall.
Education
Chambers studied physics at the University of Cambridge and graduated in 1944. After early industrial and government research appointments, he returned to Cambridge and worked with the experimental solid-state physicists David Shoenberg and Brian Pippard. He completed his PhD in 1951, developing the experimental and theoretical expertise in low-temperature physics and the electronic properties of metals that shaped his later research.
Career
Chambers began his professional life as an experimental officer at the Tank Armament Research Establishment and subsequently worked at the Electrical Research Association. After returning to Cambridge, he conducted research at the Royal Society Mond Laboratory and completed his PhD in 1951. His Cambridge work addressed the electronic properties of metals at low temperatures, including the anomalous skin effect, cyclotron resonance, magnetoresistance, and scattering theory.
In 1958 he joined the University of Bristol as a senior lecturer and was appointed to lead its Low Temperature Physics Group. He became a reader in 1961 and professor in 1964. At Bristol he carried out the technically demanding electron-interference experiment that demonstrated the Aharonov–Bohm effect, publishing the landmark result in 1960. His broader research established him as a major experimental and theoretical contributor to solid-state physics.
Chambers also played a substantial role in the administration and development of the University of Bristol. He served as Dean of Science from 1973 to 1976 and again from 1985 to 1988, and as Pro Vice-Chancellor from 1978 to 1981. In the late 1960s he helped improve communication within the University through an unofficial news-sheet that developed into the University Newsletter. During later debates over university funding and proposed institutional cutbacks, he was a prominent opponent of closure proposals. He retired from his professorship in 1990 and became Professor Emeritus. As chairman of the Standing Conference of Physics Professors from 1987, he helped promote the introduction of optional four-year physics degrees leading to the MPhys or MSci qualification.
Achievements
He won the 1994 Hughes Medal of the Royal Society for his many contributions to solid-state physics, particularly his ingenious and technically demanding experiment verifying the Aharonov–Bohm effect concerning the behaviour of charged particles in magnetic fields.
He performed the first experimental verification of the Aharonov–Bohm effect, demonstrating a shift in an electron interference pattern caused by enclosed magnetic flux.
His research on the electronic properties of metals included influential contributions to the anomalous skin effect, cyclotron resonance, magnetoresistance, and scattering theory.
As chairman of the Standing Conference of Physics Professors, he helped advance the introduction of optional four-year physics degrees leading to the MPhys and MSci qualifications.

Membership
Chambers participated in national discussions on physics education through the Standing Conference of Physics Professors, serving as its chairman from 1987. His institutional service at the University of Bristol was recognized in 1994 by the award of an honorary fellowship, the University’s highest honour.
Chambers served as chairman and led work on the development of an optional fourth year of university physics education, associated with the MPhys and MSci degrees.

Personality
Colleagues described Chambers as exceptionally intellectually rigorous and direct, while also recognizing a warmth and a calming influence beneath his demanding professional manner. He was regarded at the University of Bristol as a wise and effective participant in difficult institutional debates.
Quotes from others about the person
Colleagues at the University of Bristol remembered Chambers as a remarkable servant of the University and as a physicist whose intelligence, scientific judgment, and institutional commitment had a lasting influence on Bristol Physics.
Connections
At Cambridge, Chambers worked closely with David Shoenberg and Brian Pippard in experimental solid-state physics. At Bristol, his experimental work was closely connected with the theoretical work of Yakir Aharonov and David Bohm, whose prediction of the Aharonov–Bohm effect he tested experimentally. He was married to Sue Chambers and had a daughter, Alyssia.
