Zuckerberg, wife give $75 million to San Francisco General Hospital

SAN FRANCISCO -- Facebook founder Mark Zuckerberg is stepping up his philanthropy with a massive donation to San Francisco General Hospital.

Zuckerberg and his wife Priscilla Chan are giving a $75 million to the hospital foundation. That's the largest single private gift ever to a public hospital in the United States.

San Francisco General is the city's largest health provider for people who can't afford insurance.

The grant will help the hospital complete its new acute care and trauma center with state-of-the-art technology.

Priscilla Chan is a doctor who happened to train there.
