Art Preis (1911–1964) was a member of Socialist Workers Party National Committee from 1940 to 1963 and longtime staff writer for the socialist newsweekly the Militant. A leader of the struggle of the unemployed in northern Ohio, he took part in the 1934 Toledo Auto-Lite strike. That battle, together with strikes that year by truck drivers in Minneapolis and longshoremen in San Francisco, helped pave the way for the rise of the industrial unions across the US. Preis is the author of Labor’s Giant Step: The First Twenty Years of the AFL-CIO (1964).
