Epstein was a physicist at California Institute of Technology from 1921-1953; he taught
advanced courses in mathematical and theoretical physics. Collection includes general and family correspondence;
personal and biographical material; notebooks; manuscripts; class notes by a Caltech student; books, mostly
technical and in Russian; reprints of Epstein's writings.
Epstein was the first European-trained physicist to come to Caltech on a permanent basis. Recruited by Robert A.
Millikan in 1921, he was one of a generation of prominent mathematical physicists who laid the foundations for modern
atomic physics. Having studied and worked in Moscow, Munich, Zurich and Leyden before settling permanently in the
United States, Epstein had wide personal and scientific contacts.
