Great Lives

Warren McCulloch

1898–1969 · American neurophysiologist and pioneer of cybernetics who, with Walter Pitts, created the first mathematical model of a neural network.

Warren Sturgis McCulloch was born in Orange, New Jersey, in 1898. As a young man he planned to join the Christian ministry. He attended Haverford College and then studied philosophy and psychology at Yale University, graduating in 1921, and earned a master's degree at Columbia University in 1923 and a medical degree there in 1927. After working in New York hospitals, he returned to research in 1934 at Yale's Laboratory for Neurophysiology. In 1941 he became a professor of psychiatry at the University of Illinois at Chicago. There he invited the young logician Walter Pitts to live with his family, and together they wrote 'A Logical Calculus of the Ideas Immanent in Nervous Activity' (1943), which described how networks of simple model neurons could compute. It became a foundation of neural network theory and the theory of computation. McCulloch chaired the Macy conferences on cybernetics and from 1952 worked at the Massachusetts Institute of Technology. He also wrote sonnets and built a dam on his farm in Connecticut. He married Ruth Metzger in 1924, and they had three children. He died in 1969.
