Berkeley alumni—often generous benefactors—have long been among the billionaire ranks, their largess giving rise to many of the campus' eponymous schools, pavilions, centers, institutes, and halls, and with some of the more prominent being J. Paul Getty, Ann Getty, Sanford Diller and Helen Diller, Donald Fisher, Flora Lamson Hewlett, David Schwartz (Bio-Rad) and members of the Haas (Walter A. Haas, Rhoda Haas Goldman, Walter A. Haas Jr., Peter E. Haas, Bob Haas), Hearst, and Bechtel families. There are at least 29 living alumni billionaires: Gordon Moore (Intel founder), James Harris Simons (Renaissance Technologies), Masayoshi Son (SoftBank), Jon Stryker (Stryker Medical Equipment), Eric Schmidt (former Google Chairman) and Wendy Schmidt, Michael Milken, Bassam Alghanim, Kutayba Alghanim, Charles Simonyi (Microsoft), Cher Wang (HTC), Robert Haas (Levi Strauss & Co.), Carlos Rodriguez-Pastor (Interbank, Peru), Fayez Sarofim, Daniel S.
