Willie Mae Thornton (December 11, 1926 – July 25, 1984), better known as Big Mama Thornton, was an American rhythm-and-blues singer and songwriter. She was the first to record Leiber and Stoller's "Hound Dog", in 1952, which became her biggest hit, staying seven weeks at number one on the Billboard R&B chart in 1953 and selling almost two million copies. Thornton's other recordings included the original version of "Ball and Chain", which she wrote.
