Dixie Graves (née Bibb; July 26, 1882 – January 21, 1965) was a First Lady from the State of Alabama and the first woman to serve as a United States Senator from Alabama. She was appointed to the Senate by her husband, Governor Bibb Graves, when Senator Hugo Black resigned in order to serve on the U.S. Supreme Court in August 1937. Graves was succeeded by fellow Democrat Lister Hill, who would serve for over 3 decades.
