Joe Glaser (December 17, 1896 – June 6, 1969) was an artist manager famous for his involving in the career of several Jazz musicians, mainly Louis Armstrong and Billie Holiday. He was the son of a Chicago family of Russian Jewish origins. After a series of irregular jobs (fight promoter, club manager...) mostly based on his mob connections, he started managing Louis Armstrong in May 1935, the success in their association caused that other jazz musicians moved to his company ABC Artists Management. Although his clients had a high opinion of him, he was a feared person in the business industry. The company ABC "was formed in 1940 by Joe Glaser and Louis Armstrong". It has represented Duke Ellington, Benny Goodman, Lionel Hampton, Woody Herman, Dave Brubeck, Barbra Streisand, B.B. King, The Allman Brothers Band, T. Rex, and many others.
