Samueli is also a well-known philanthropist. Forbes estimates his worth to be more than US $6 billion, and he and his wife, Susan, are members of the Giving Pledge. The group consists of many of the world’s leading philanthropists, who promise to give away the majority of their money during their lifetime.
Samueli doesn’t give anonymously. He and his wife believe it is important to have their philanthropy be visible because, he says, “We want to set an example and motivate others to get involved in philanthropy and be proud to show it.”
