Valentine Bargmann
Valentine "Valya" Bargmann (April 6, 1908 – July 20, 1989)[1] was a German-American mathematician and theoretical physicist.After the National Socialist Machtergreifung, he moved to Switzerland to the University of Zürich where he received his Ph.D. under Gregor Wentzel.He emigrated to the U.S., barely managing immigration acceptance, as his German passport was to be revoked with only two days of validity left.At the Institute for Advanced Study in Princeton (1937–1946) he worked as an assistant to Albert Einstein,[2] publishing with him and Peter Bergmann on classical five-dimensional Kaluza–Klein theory (1941).He further formulated the Bargmann–Wigner equations with Eugene Wigner (1948), for particles of arbitrary spin, building up on work of several theorists who pioneered quantum mechanics.
