65. Gordon Moore
The cofounder of semiconductor giant Intel is also the namesake of Moore’s Law, his prediction more than 50 years ago that computer processing power would double every year. Moore and his wife, Betty, are prolific philanthropists. In March they donated $50 million to the Lucile Packard Children’s Hospital at Stanford, where one of their grandchildren had lifesaving surgery. While a student at UC Berkeley, Moore designed a rocket engine as a member of the Rocket Society.
