Thomas "Fats" Waller (1904-1943) was a prolific jazz pianist, organist, composer, and entertainer whose contributions helped define the stride piano tradition and the American popular song. Born in Harlem, he emerged from the tutelage of stride master James P. Johnson to become one of the era's most prolific keyboard composers and the first jazz musician to master the pipe organ. Waller copyrighted over 400 compositions during his career, though financial pressures led him to sell many works outright, likely without proper credit. His most enduring standards include "Ain't Misbehavin'," "Honeysuckle Rose," "Black and Blue," "Squeeze Me," and "Handful of Keys," most written in collaboration with lyricist Andy Razaf. His "Jitterbug Waltz" demonstrated his ability to merge swing rhythms with the waltz form. As a Broadway composer, he broke barriers with shows like Keep Shufflin' (1927) and Early to Bed (1943), the latter making him one of the first African American songwriters to compose a hit Broadway musical for primarily white audiences. Waller's writing combined rhythmic drive with harmonic sophistication, later incorporating impressionist influences in works like his London Suite (1938). A central figure in both the Harlem Renaissance and the swing era, he left a legacy recognized by the Grammy Hall of Fame's induction of both "Ain't Misbehavin'" and "Honeysuckle Rose." He died in 1943 at age 39 while traveling by train through Kansas City.
