Life

William Massey was born in Granville, Illinois, in 1920, the son of Robert and Alma Massey, and grew up in Peoria. He was an undergraduate student at the University of Chicago. After serving as a meteorologist aboard aircraft carriers in the United States Navy for 4 years during World War II, he received a Ph.D. degree from Princeton University in 1949.[2] His dissertation, entitled Classification of mappings of an -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.[3] He then taught for ten years on the faculty of Brown University. In 1958 he was elected to the American Academy of Arts and Sciences.[4] From 1960 till his retirement he was a professor at Yale University. He died on June 17, 2017, in Hamden, Connecticut.
