Early life
Sidney Lens was born Sidney Okun on January 12, 1912, in Newark, New Jersey, to Charles and Sophie Okun, Jewish immigrants from Russia who had arrived in the United States in 1907. His father, who was a pharmacist, died when Lens was three years old, and he was raised by his single mother who worked long hours in the New York City garment industry. Lens changed his name in the early 1930s.
Raised in the Lower East Side neighborhood in New York City, Lens attended Rabbi Jacob Joseph School and DeWitt Clinton High School. He briefly enrolled at New York University night school, but left without a degree.
Career
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. His archives are preserved by the Chicago History Museum Research Center.
