Thomas "Fats" Waller (1904-1943) was a pianist, organist, and composer who became one of jazz's most influential figures during the swing era. His harmonic sophistication, rhythmic vitality, and infectious sense of humor shaped the sound of American jazz and popular song in the 1920s and 1930s. Beyond his virtuosic keyboard work, Waller composed or co-composed hundreds of songs that remain central to jazz repertoire, including "Ain't Misbehavin'," "Black and Blue," and "Honeysuckle Rose."
Waller's legacy extends far beyond his recordings and performances. His improvisational approach to jazz piano, marked by stride technique, sophisticated comping, and melodic invention, continues to influence pianists and composers across genres. For music educators, Waller's work demonstrates how technical mastery, harmonic understanding, and personality combine to create music that endures.
