On September 15, 1951, Robbie Page, the son of Tri Sigma's National President, died of bulbar polio, a disease which at that time had no cure or vaccine; this death prompted his parents to establish a memorial fund in his honor. The sorority adopted this fund as its official philanthropy in 1954. In its early years, the RPM supported various polio research projects, including the Salk vaccine trials. It now focuses on supporting play therapy for hospitalized children and providing support for playrooms, libraries, and programs for children undergoing long-term hospital care.
