Robert Hermann (mathematician)

Robert C. Hermann (April 28, 1931 – February 10, 2020) was an American mathematician and mathematical physicist. In the 1960s Hermann worked on elementary particle physics and quantum field theory, and published books which revealed the interconnections between vector bundles on Riemannian manifolds and gauge theory in physics, before these interconnections became "common knowledge" among physicists in the 1970s.

Biography

Born in Brooklyn, Hermann studied in Paris and at Princeton University, where he attended lectures by Charles Ehresmann and where in 1955 under Donald Spencer he received his PhD with thesis The Differential geometry of homogeneous spaces. He was a Benjamin Peirce Instructor at Harvard University in 1957, and researcher at MIT Lincoln Laboratory 1959 to 61 when he lectured at University of California Berkeley. In 1962 he became an associate professor at Northwestern University and was raised to full professor. In 1967 he taught at University of California Santa Cruz until moving to Rutgers University (1970 to 75). Subsequently he did research primarily with financial support from the Ames Research Center of NASA. In the academic year 1969/1970 he was at the Institute for Advanced Study.

Following the French school of Élie Cartan, Hermann published numerous books on differential geometry and Lie group theory and their applications to differential equations, integrable systems, control theory, and physics. Most of these books were published in Brookline, Massachusetts by Math Sci Press, which he founded. Two series were published: a green series "Interdisciplinary Mathematics" and a blue series "Lie Groups: History, Frontiers and Applications".
