Wallie Abraham Hurwitz (February 18, 1886 in Joplin, Missouri – January 6, 1958 in Ithaca, New York) was an American mathematician who worked on analysis.

He won a Sheldon Traveling Fellowship, which enabled him to study at the University of Göttingen, where he earned a doctoral degree under Hilbert in 1910.

In 1912 Hurwitz joined the mathematics faculty of Cornell University, where he remained until he died in 1958 at age seventy-one.

Hurwitz had an extensive knowledge of music and a large collection of Gilbert and Sullivan scores, reviews, programs, and related memorabilia.

He invested brilliantly in the stock market, selling out shortly before the 1929 crash and buying in close to the bottom.
