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,"[1] and she left the bulk of her assets to the Colcom Foundation, whose major activity has been the sponsorship of immigration restriction.[1]
May lived a reclusive life, especially after the death of her second husband in 1974.[2]
