Career in civil rights
In 1945 he became executive director of the National Community Relations Advisory Council, now known as the Jewish Council for Public Affairs, a position he retained until 1976. With Randolph and Wilkins, Aronson was a founder of the Leadership Conference on Civil Rights in 1950.[5] As secretary of the Leadership Conference, he helped coordinate lobbying efforts for the Civil Rights Act of 1957, the Civil Rights Act of 1964, the Voting Rights Act of 1965, and the Fair Housing Act of 1968.[6] Although one of the few white leaders involved in planning the 1963 March on Washington, Aronson downplayed his participation. After he retired, he founded The Leadership Conference Education Fund and served as its director until his death.
President Bill Clinton awarded him the Presidential Medal of Freedom on January 15, 1998.
He and his wife Annette had two sons, Simon Aronson of Chicago and Bernard Aronson of Takoma Park, Maryland. His nephew, singer-songwriter and organizer Si Kahn, credits his uncle with helping inspire and shape his own work.[7]
