Mark Zuckerberg and his wife, Priscilla Chan, have just announced a huge donation to San Francisco General Hospital.

The couple is giving $75 million to the hospital, which is called The General, to expand the size of the ER and provide more beds for patients.

“To add some specifics, our contribution today will allow The General to double the size of its new Emergency Room and quadruple the number of beds, and provide state of the art equipment for healthcare providers and first responders,” says Zuckerberg.

“We believe everyone deserves access to high quality health care. The General is the main public hospital in San Francisco, and it is an important safety net for our community. More than 70% of the families it serves are uninsured or underinsured. It is open to anyone who lives, works in or visits the city … We hope this contribution alongside the great work of other contributors, will help The General to continue to save lives and deliver care to everyone who needs it.”

Chan is a pediatrician. She completed her residency at The General.

In October, Zuckerberg gave the Centers for Disease Control $25 million to help battle Ebola in Africa. In May, he donated $120 million to help improve Bay Area schools.
