born Dec. 18, 1898, Cuthbert, Ga., U.S.
died Dec. 29, 1952, New York, N.Y.
U.S. pianist, arranger, and leader of one of the most influential big bands in jazz .
Henderson formed a dance band in New York in 1923. The band soon distinguished itself in two ways: the engagement of Louis Armstrong as principal soloist placed greater emphasis on swinging improvisation and the arrangements by Henderson and Don Redman (190064) codified the roles of the sections within the ensemble to replace the collective improvisation of early jazz groups. Nearly all big bands subsequently followed their example. A poor businessman, he was forced to dissolve his band several times, but his arrangements played a key role in the success of Benny Goodman in the late 1930s and provided a template for much of the music of the swing era.
