LOS ANGELES (AP) _ Hollywood mogul David Geffen is donating $200 million to the UCLA medical school _ the largest, single donation ever given to a U.S. medical school.

The 50-year-old school will be renamed the David Geffen School of Medicine at UCLA. School officials said the donation is unrestricted, which means they can decide how to use the money.

``This is a university's dream kind of gift,'' UCLA Chancellor Albert Carnesale said.

In a statement issued Tuesday, Geffen said he wants to continue to support Los Angeles-based organizations.

Geffen, 59, co-founder of the entertainment production company DreamWorks SKG, has donated millions of dollars to other medical-related causes. They include gifts of $2.5 million to AIDS Project Los Angeles, $2.5 million to the Gay Men's Health Crisis in New York, and $1.4 million to AIDS Action in Washington.

Geffen also has given to UCLA before. A $5 million donation resulted in the naming of the school's theater as the Geffen Playhouse.

As of last June, the UCLA medical school's endowment was more than $587 million. The money drawn annually from Geffen's gift will go toward training medical scientists, research and providing financial aid for students, said Gerald S. Levey, dean of the UCLA medical school.

``I have great respect and affection for UCLA, and my hope is that with this gift, UCLA's doctors and researchers will be better equipped to unravel medicine's mysteries _ and deliver the cures for tomorrow,'' Geffen said.
