Thomas Wright "Fats" Waller (May 21, 1904 – December 15, 1943) was an American jazz pianist, organist, composer, violinist, singer, and comedic entertainer. His innovations in the Harlem stride style laid the groundwork for modern jazz piano. His best-known compositions, "Ain't Misbehavin'" and "Honeysuckle Rose", were inducted into the Grammy Hall of Fame in 1984 and 1999. Waller copyrighted over 400 songs, many of them co-written with his closest collaborator, Andy Razaf. Razaf described his partner as "the soul of melody... a man who made the piano sing... both big in body and in mind... known for his generosity... a bubbling bundle of joy". It is possible financial circumstances caused him to compose many more popular songs and sell them to other performers.
