Walter Gropius, Marcel Breuer, and Moholy-Nagy re-assembled in Britain during the mid 1930s to live and work in the Isokon project before the war caught up with them. Gropius and Breuer went to teach at the Harvard Graduate School of Design and worked together before their professional split. Their collaboration produced the Aluminum City Terrace in New Kensington, Pennsylvania and the Alan I W Frank House in Pittsburgh, among other projects. The Harvard School was enormously influential in America in the late 1920s and early 1930s, producing such students as Philip Johnson, I. M. Pei, Lawrence Halprin and Paul Rudolph, among many others.
