Fats Waller (May 21, 1904 - December 15, 1943) born Thomas Wright Waller was an American jazz pianist, organist, composer and comedic entertainer. He was the youngest of four children born to Adaline Locket Waller, wife of the Reverend Edward Martin Waller.
Fats Waller started playing the piano when he was six and graduated to the organ of his father's church four years later. At the age of fourteen he was playing the organ at Harlem's Lincoln Theater and within twelve months he had composed his first rag. Waller's first piano solos (Muscle Shoals Blues and Birmingham Blues) were recorded in October 1922 when he was just 18 years old.
He was a skilled pianist, and master of stride piano, having been the prize pupil and later friend and colleague of the greatest of the stride pianists, James P. Johnson. Waller was one of the most popular performers of his era, finding critical and commercial success in his homeland and in Europe. He was also a prolific songwriter, and many songs he wrote or co-wrote are still popular, such as "Honeysuckle Rose", "Ain't Misbehavin'" and "Squeeze Me". Fellow pianist and composer Oscar Levant dubbed Waller "the black Horowitz". Waller composed many novelty swing tunes in the 1920s and 30s, and sold them for relatively small sums. When the compositions became hits, other songwriters claimed them as their own. Many standards are alternatively and sometimes controversially attributed to Waller.
