# Marston Morse

**Harold Calvin Marston Morse** (March 24, 1892 – June 22, 1977) was an American mathematician best known for his work on the *calculus of variations in the large*, a subject where he introduced the technique of differential topology now known as Morse theory. The Morse–Palais lemma, one of the key results in Morse theory, is named after him, as is the Thue–Morse sequence, an infinite binary sequence with many applications. In 1933 he was awarded the Bôcher Memorial Prize for his work in mathematical analysis.
