Alan Turing
Studying Under Alonzo Church at Princeton University
Princeton, New Jersey, U.S.
From September 1936 to July 1938, Turing spent most of his time studying under Alonzo Church at Princeton University, in the second year as a Jane Eliza Procter Visiting Fellow. In addition to his purely mathematical work, he studied cryptology and also built three of four stages of an electro-mechanical binary multiplier.
