David Eugene Smith (January 21, 1860 – July 29, 1944) was an American mathematician, educator, and editor.

He studied to be a lawyer concentrating in arts and humanities, but accepted an instructorship in mathematics at the Cortland Normal School in 1884 [2] where he attended as a young man.

While at the Cortland Normal School Smith became a member of the Young Men's Debating Club[3] (today the Delphic Fraternity.)

He became a professor at the Michigan State Normal College in 1891 (later Eastern Michigan University), the principal at the State Normal School in Brockport, New York (1898), and a professor of mathematics at Teachers College, Columbia University (1901) where he remained until his retirement in 1926.
