Frances Perkins was an American workers-rights advocate who served as the U.S. Secretary of Labor from 1933 to 1945, the longest serving in that position. She made history as the first woman to serve in any presidential U.S. Cabinet. As a loyal supporter of her longtime friend, Franklin D. Roosevelt, she helped make labor issues important in the emerging New Deal coalition. She was one of two Roosevelt cabinet members to remain in office for his entire presidency.
Her most important role came in developing a policy for Social Security in 1935. She also helped form governmental policy for working with labor unions, although the union leaders distrusted her. Her Labor Department helped to alleviate strikes by way of the United States Conciliation Service. Perkins dealt with many labor questions during World War II, when skilled labor was vital and women were moving into jobs formerly held by men. She was the subject of the documentary film Summoned.
