Born in Boston, MA of Jewish Russian immigrants, he studied mathematics at Harvard University, from which he was awarded a B.Sc. (1911), a M.Sc. (1912) and Ph.D. on the thesis On the Functions of a Complex Variable Defined by an Ordinary Differential Equation of the First Order and First Degree advised by George Birkhoff (1913). Meanwhile, he also worked at Boston Elevated Railway.

After his Ph.D., he became Sheldon fellow at University of Göttingen in Germany, was at University of Sorbonne in Paris, before becoming instructor of mathematics at Cornell University (1915). He joined Westinghouse Electric in East Pittsburgh (1916) in the railway motor department initially, moving to the research department (1917) at Forest Hills (PA) where he became head (1922), consulting engineer (1926) and associate director (1938–1956) and developed over two hundred patents.[2] Slepian did significant groundwork for the betatron (1927). He received the IEEE Edison Medal (1947) for his work on the autovalve lightning arrester, deion circuit breaker, and ignitron.

He wrote over 120 articles and essays, and published the book Conductivity of electricity in gases (1933).[3] His career was somewhat shortened by a stroke (1951). He was the father of the mathematician David Slepian.
