David W. (Doc) Tucker was raised as an only child in a small central Illinois town, Cerro Gordo, where he attended the public schools.
His responsibilities with the Cal Band included rehearsing, auditioning prospective new members, and directing on the football field opposite director James Berdahl.
Among professional composers who studied with Tucker are Rolf Johnson, Michael Wolff, and Susan Muscarella of the JazzSchool in Berkeley.
Tucker directed the University of California Jazz Ensembles until 1985, his early retirement resulting largely from a bad back that had him lying flat for a year.
Each year 100 students worked under his direction in the Monday, Tuesday, and Wednesday night big bands, combos, and classes.
Under Tucker's guidance, the University of California Jazz Ensembles became the most successful and visible performing arts organization on the Cal campus.
The group received critical acclaim and a last-minute concert was arranged by the sponsors at the Japanese major league baseball Korakuen Stadium.
In the service with the army he was principal trombone with the Fort Smith Symphony and directed the 5th Armored Division public relations tours and radio broadcasts.
Others, provided the opportunity to be soloists and announcers for the organization, embarked on careers as musician agents, music producers, radio disk jockeys, and stand-up comedians.
