William and Flora Hewlett Foundation
Hewlett-Packard cofounder Bill Hewlett and his wife, Flora, formed the William and Flora Hewlett Foundation in 1966 to address social and environmental issues. With more than $8 billion in assets, the Hewlett Foundation donates approximately $300 million annually. The foundation distributes grants worldwide in the areas of global development, education, performing arts, reproductive health, and environmental issues. It also funds programs to aid underprivileged communities in the San Francisco area where the foundation has its headquarters.
