Peter Dalis, who served as athletic director at UCLA during a 19-year stretch in which the school won 39 NCAA championships, died Saturday. He was 76.

The school said he died of complications from multiple myeloma at his home in Pacific Palisades, where he was surrounded by his family.

When he retired in 2002, Dalis was the Pacific-10's longest serving athletic director. The football team played in 12 bowl games and won eight during his tenure. The men's basketball team made 15 NCAA tournament appearances, winning a national title in 1995 and reaching the regional final twice and the Sweet 16 five other times.

Dalis oversaw construction of the J.D. Morgan Center, which provided private offices for coaches and administrators, a new academic and counseling center for athletes and a new Hall of Fame.
