Lens became a socialist in the early 1930s, and joined the
American Workers Party (
Trotskyist) in 1934. He focused on
union organizing as the primary vehicle for revolutionary change. Lens helped organize department store and auto workers in the 1930s, and participated in the
Flint sit-down strike in 1936. Among those he was influenced by was the Dutch-American pacifist
A.J. Muste. Lens was a contributor to
The Progressive and wrote more than twenty books. He ran for public office three times, culminating in 1980 when he was the
Citizens Party (United States) candidate for
United States Senate in
Illinois. Along with his 1977 book
The Day Before Doomsday which warned of the dangers of nuclear war, Lens also wrote a history of U.S. intervention abroad,
The Forging of the American Empire, originally published in 1974 and republished in 2003 by
Haymarket Books with a new introduction by
Howard Zinn; and an
autobiography,
Unrepentant Radical. ==Personal life==
