**Stanley Wagon** is a Canadian-American mathematician, a professor of mathematics at Macalester College in Minnesota. He is the author of multiple books on number theory, geometry, and computational mathematics, and is also known for his snow sculpture.

## Biography

Wagon was born in Montreal, and did his undergraduate studies at McGill University in Montreal, graduating in 1971. He earned his Ph.D. in 1975 from Dartmouth College, under the supervision of James Earl Baumgartner. He married mathematician Joan Hutchinson, and the two of them shared a single faculty position at Smith College and again at Macalester, where they moved in 1990.^{[1]}^{[2]}^{[3]}
