The Los Angeles branch of the National Urban League stems from a 1921 organization founded by Katherine Barr and others who attended Booker T. Washington's Tuskegee Institute in Alabama. The league gathered information about racial discrimination against African Americans and other minorities in jobs, health services, and housing; helped develop fair employment programs during World War II, and was active in the formation of the City Human Relations Commission.
