## About

William K. Bowes, Jr. established this California private foundation in 1991, channeling wealth generated from a defining career in early-stage life sciences and technology investing. As a co-founder of U.S. Venture Partners and the founding shareholder and first chairman of Amgen, Bowes helped shape the biotechnology industry from its earliest days. Following his death in 2016, his widow Ute Bowes assumed the presidency, continuing the foundation's grantmaking from its San Francisco headquarters. The foundation deploys capital exclusively through grants to nonprofit organizations across three core priorities: medical research, college access and education, and the arts. Unlike venture philanthropy models that make program-related investments or take equity positions, the William K. Bowes, Jr. Foundation operates purely as a grantmaker. It does not accept unsolicited proposals, funding only organizations invited to apply. The investment corpus — estimated at roughly $237 million — supports an annual grantmaking operation that has backed institutions including the San Francisco General Hospital Foundation, reflecting a geographic concentration in the Bay Area alongside select national recipients. The foundation's endowment portfolio spans corporate bonds alongside other traditional asset classes managed to preserve purchasing power for perpetual grantmaking. The foundation is staffed leanly, with Chris Perkins serving as CFO and Vice President alongside President Ute Bowes. The foundation maintains its offices at 1660 Bush Street and has supported major civic projects including the Ute and William K. Bowes, Jr. Center for the Performing Arts at 200 Van Ness Avenue. Through the Northern California Grantmakers network, the foundation participates in regional philanthropic coordination, though its grantmaking decisions remain independent and internally directed. William K. Bowes, Jr. was recognized as Outstanding Philanthropist by the Golden Gate Chapter of the Association of Fundraising Professionals, an honor reflecting the foundation's sustained presence in Bay Area institutional giving. The foundation's structural distinction lies in its dual identity: it functions as perpetual steward of a fortune built at the frontier of American venture capital and biotechnology, yet operates as a traditional private foundation with no program-related investment mandate. Unlike many tech-derived foundations that blur grantmaking with impact investing, the Bowes Foundation maintains a hard separation — endowment management serves grantmaking, and grantmaking remains confined to invited charitable distributions. The explicit prohibition on unsolicited proposals further concentrates decision-making with the foundation's small leadership team, preserving the founder's intent without the broad public-facing processes common to larger institutional foundations.
