Keck Foundation gives $150 million to USC medical school

The W. M. Keck Foundation on Monday will announce a $150 million gift to boost scientific research at USC's medical school and at two affiliated hospitals, adding to the university's recent success in attracting supersized donations.

The gift is the single largest in the 57-year history of the Keck Foundation, which has backed many scientific projects, including the famous Keck Observatory and telescopes in Hawaii. For USC, the money marks the third mega-gift since March, for a total of $460 million.
