He graduated from the University of Chicago and Western Reserve University with a master's degree in 1928. He was an organizer of the Flint Sit-Down Strike, and edited The Flint Auto Worker. Sol Dollinger was critical of his account of the strike.
He married Dorothy Kraus, who helped organize the UAW Women's Auxiliary. He was the first editor of the United Automobile Workers' newspaper, The United Auto Worker. He moved to Paris, and worked as a European correspondent for World Wide Medical News Service. His papers are at the Walter P. Reuther Library, Wayne State University.
The Henry Kraus Papers at the Walter P. Reuther Library date from 1926-1960. His papers reflect his attempts to organize auto workers and the early history of the United Automobile Workers from 1935-1941. Particularly well-documented in the collection are the Flint sit-down strike and factionalism within the UAW.
