**William Schumacher Massey** (August 23, 1920^{[1]} – June 17, 2017) was an American mathematician, known for his work in algebraic topology. The Massey product is named for him. He worked also on the formulation of spectral sequences by means of exact couples, and wrote several textbooks, including *A Basic Course in Algebraic Topology* (ISBN 0-387-97430-X).

## Life

William Massey was born in Granville, Illinois in 1920. He was an undergraduate student at the University of Chicago. After serving in the United States Navy during World War II, he received a PhD degree from Princeton University in 1949. His dissertation, entitled *Classification of mappings of an (n+1)-dimensional space into an n-sphere,* was written under the direction of Norman Steenrod. He spent two additional years at Princeton as a post-doctoral research assistant. He then taught for ten years on the faculty of Brown University. From 1960 till his retirement he was a professor at Yale University. He died on June 17, 2017 in Hamden, Connecticut. He had 23 PhD students, including Donald Kahn and Larry Smith.
