George Novack (August 5, 1905, Boston, Massachusetts – July 30, 1992, New York City) was an American Marxist theoretician, editor, and activist.Novack attended Harvard University for five years, though without earning a degree, and was on a successful track in the publishing business when the beginning of the Great Depression radicalized him.He joined the Trotskyist movement (Communist League of America) in 1933, along with his first wife Elinor Rice, and was an elected member of the National Committee of the Socialist Workers Party (SWP) from 1940 to 1973.This body initiated the celebrated 1937 Dewey Commission that inquired into the charges made against Trotsky in the Moscow show trials, and found them to have been a complete frame-up.He played a major role in the defense campaign for the 18 SWP leaders imprisoned in World War II under the Smith Act.
