William S. Heckscher
In 1932–1933, Heckscher lived in New York where he worked as Panofsky's assistant. During this time, he enrolled in the Graduate Department of Art History at the Institute of Fine Arts at New York University to study American art history. Heckscher returned to Germany to continue his studies in 1934. He and his mother were detained by the Gestapo and interrogated for ten days after being accused of having pacifist connections.
