American heiress and recluse
Cordelia Scaife May (September 24, 1928 – January 26, 2005) was a Pittsburgh, Pennsylvania area political donor and philanthropist. An heiress to the Mellon Scaife family fortune, she was one of the wealthiest women in the United States. Her philanthropy and political causes included environmentalism, birth control and family planning; overpopulation control measures, making English the official language of the United States, and strict immigration restrictions to the United States. According to The New York Times, "she bankrolled the founding and operation of the nation’s three largest restrictionist groups—the Federation for American Immigration Reform, NumbersUSA and the Center for Immigration Studies," and she left the bulk of her assets to the Colcom Foundation, whose major activity has been the sponsorship of immigration restriction. May's maternal grandfather was Richard B. Mellon. May is the grandniece of Andrew W. Mellon. The cause of death was suicide by asphyxiation after a struggle with pancreatic cancer. She was survived by her estranged brother Richard, with whom she had partially reconciled in 1999. In 1996, May established Colcom Foundation. May served as the chairman of both foundations until her death in 2005. In the year 1972, May was the single largest contributor to candidates running for Congress.

May's largesse helped fund a number of projects in the Pittsburgh area, including the Pittsburgh National Aviary, the Montour Trail, the Riverlife Task Force, the Pittsburgh Parks Conservancy, and the Women's Center & Shelter of Greater Pittsburgh. By 1952 she began to actively address national population issues. There is a bust of Margaret Sanger in the National Portrait Gallery which was a gift from May. By 1974, she had resigned from Planned Parenthood, based on her view that family planning was a waste of money in the presence of massive immigration.

May opposed immigration. She argued the United States was "being invaded on all fronts" by immigrants who "breed like hamsters" and exhaust America's resources. The Los Angeles Times reported that Scaife May was the single largest donor to anti immigrant causes and "An ardent environmentalist more comfortable with books and birds than with high society galas, May believed nature was under siege from runaway population growth. Before her death in 2005, she devoted much of her wealth to rolling back the tide backing birth control and curbing immigration, both legal and illegal." The Times also wrote that May donated $200,000 to conservative columnist Samuel T. Francis, who called for a halt to all immigration and who opposes the mixing of the races.
