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.

He was educated at the Collegiate School, 27/28 Charlotte Square in Edinburgh. He then trained for the Indian Civil Service with Wren and Gurney but, falling very ill, was instructed to go to Australia to improve his health. During this sea journey he became interested in navigational mathematics. He arrived at Melbourne during a financial panic and then got mixed up in the Coolgardie Gold Rush of 1892. After two years of little success as a gold miner he returned to Scotland in 1894.
