Cassius Jackson Keyser (May 15, 1862, Rawson, Ohio -- May 8, 1947 New York City) was an American mathematician of pronounced philosophical inclinations.

[edit] Life

Keyser's initial higher education was at North West Ohio Normal School (now Ohio Northern University), then became a school teacher and principal. In 1885, he married a fellow student at the Normal School, Ella Maud Crow of Ridgeway, Ohio. He completed a second undergraduate degree, a BSc, at the University of Missouri in 1892. After teaching there, at the New York State Normal School (now SUNY New Paltz), and at Washington University, he enrolled as a graduate student at Columbia University, earning the MA in 1896 and the Ph.D. in 1901. He spent the rest of his career at Columbia, becoming the Adrain Professor of Mathematics (1904-27) and Head of the department (1910-16). He retired in 1927.

Keyser was one of the first Americans to appreciate the new directions in the foundation of mathematics, heralded by the work of Europeans such as Dedekind, Georg Cantor, Peano, Henri Poincare, Hilbert, Zermelo, Bertrand Russell, and A. N. Whitehead. He was also one of the first to appreciate the mathematical and philosophical importance of his fellow American Charles Peirce. Alfred Korzybski, founder of general semantics, named Keyser as a major influence. While at Columbia, Keyser supervised only three PhDs, but they all proved quite consequential: Eric Temple Bell, the logician Emil Post, and Edward Kasner.

He became a member of the American board of the Hibbert Journal, and made contributions to that and other philosophical journals.[1]Together with his Columbia colleague John Dewey, Keyser helped found the American Association of University Professors (AAUP). He was a fellow of the American Academy for the Advancement of Science, and a member of the American Mathematical Society.
