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.
Emil Huschke
He studied medicine at the University of Jena, and spent most of his professional career at Jena. In 1827 he was appointed professor of anatomy and director of the anatomical institute. Huschke was politically active and took part in the foundation of the "Deutsche Burschenschaft", a student movement for German national unity. In 1867 his daughter, Agnes Huschke, married famed biologist Ernst Haeckel (1834-1919).
