Arnold Maurice Jacobs (June 11, 1915 – October 7, 1998) was an American tubist who spent most of his career with the Chicago Symphony Orchestra.
Jacobs was considered one of the foremost brass pedagogues of his time as well as an expert on breathing as it related to brasswind, woodwind, and vocal performance.
When he was fifteen years old, he entered Philadelphia's Curtis Institute of Music on a scholarship and continued to major in tuba.
In June 1962, he had the honor of being the first tuba player invited to play at the Casals Festival in Puerto Rico.
Mr. Jacobs and with colleagues from the CSO were part of the famous 1968 recording of Gabrieli's music with members of the Philadelphia and Cleveland Orchestras.
He was one of the most sought-after teachers in the world, specializing in respiratory and motivational applications for brass and woodwind instruments and voice.
In January 1978, he lectured at Chicago's Michael Reese Hospital about playing wind instruments for the therapeutic treatment of asthma in children.
Mayor Richard M. Daley proclaimed June 25, 1995, as Arnold Jacobs Day in the City of Chicago.
