On Jul. 29, 1999, the University of Southern California (USC) announced that it had received a gift of $110 million from the W.M. Keck Foundationﾗthe largest gift ever made to a medical school at the time and the largest single gift ever made by the Keck Foundation.

USC, which committed to raising $330 million in matching funds, renamed its medical school the Keck School of Medicine of the University of Southern California to recognize the generosity of the foundation.
