Frances Perkins was an American workers-rights advocate who served as the fourth United States Secretary of Labor from 1933 to 1945, the longest serving in that position. A member of the Democratic Party, Perkins was the first woman ever to serve in a presidential cabinet. As a loyal supporter of her longtime friend, President 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.
