Biggest ever donation for Oxbridge college

Pembroke College, Cambridge, is set to benefit from what it says is the largest gift ever made to a Cambridge or Oxford college.
In a statement released this week, Lord Smith, a former cabinet minister under Tony Blair and now Master of Pembroke College, said that Dagmar, the widow of Ray Dolby, and her family, had made “an astonishing gift of £35 million ($52.9 million) to the college.”

Born in Portland, Oregon, in 1933, Ray Dolby went to Pembroke in 1957 to study for a PhD. He is best known for founding Dolby Laboratories in London in 1965. A year later, the company created what it says was “the first product to reduce noise in music recordings” while in 1982 it created the surround sound system for home users.

While the Dolby gift is not insignificant by any means, it is dwarfed by the $400 million gift made by John A. Paulson to Harvard in June. The endowment will support Harvard’s School of Engineering and Applied Sciences.
