Drummond Pike

In 2008, Pike anonymously donated $1 million to ACORN after Dale Rathke, the brother of ACORN's founder Wade Rathke, was found to have embezzled $948,607.50 from the group and affiliated charitable organizations. ACORN had previously received funding from the Tides Foundation.

In 2002, Pike became the founding chairman of Tides Canada Foundation, a parallel organization of the Tides Foundation.

In 1996, Pike established the Tides Center, an offshoot of the Tides Foundation. The Tides Center provides grants management, administrative, financial and human resources services to charitable initiatives not yet incorporated as 501(c)(3)s.

Pike founded Groundspring.org in 1996. Groundspring.org was originally called eGrants and was later acquired by Network for Good.

Pike was among the original founders of Working Assets (Credo), a San Francisco-based telecommunications company dedicated to progressive philanthropy and political activism. He founded Highwater, Inc., a real estate development venture designed to facilitate the provision of quality nonprofit workspace in metropolitan areas, in 1992. In 1994 he proposed the Thoreau Center for Sustainability to the Presidio Trust.

Pike founded the Tides Foundation, the first fully staffed donor-advised fund in the United States, in 1976. At Tides, he pioneered the use of donor-advised funds as an instrument for donors to anonymously support philanthropic causes.

In 1975, Pike co-founded the Youth Project in Washington D.C., serving as its associate director. He was subsequently hired as executive director of the Shalan Foundation, based in San Francisco.

Pike studied political science at the University of California, Santa Cruz, and became involved in the anti-war movement in the late 1960s. He was selected as a campus representative to the Board of Regents during his senior year in 1969, and graduated with a B.A. in 1970. Pike continued his education at the Eagleton Institute of Politics at Rutgers University where he obtained a master's degree in Political Science.
