Hal Draper (1914-1990) was another American Marxist who upheld Third
Camp politics. Draper joined the socialist movement in 1932, becoming
a national organiser of the Young People's Socialist League, the
youth group associated with the Socialist Party. He became a
Trotskyist and was a founder member of the SWP-USA in 1938.
In the 1939-40 split Draper sided with Shachtman. During the Second
World War he worked in the shipyards in Los Angeles, helping to
organise wildcat strikes.
After the war, and especially in the 1950s, Draper became a leading
writer for the Workers Party and the Independent Socialist League,
eventually producing the ISL paper Labor Action almost single-handed.
He distanced himself from Shachtman after 1958, writing, for example,
a stinging attack on Shachtman's support for the US-backed Bay of
Pigs invasion of Cuba in April 1961.
He formed a group called the Independent Socialist Club, but after
1971 he withdrew from active politics and turned to writing scholarly
works, notably the five-volume "Karl Marx's Theory of Revolution".
