amfAR, The Foundation for AIDS Research, (AMerican Foundation for Aids Research) is an international nonprofit organization dedicated to the support of AIDS research, HIV prevention, treatment education, and the advocacy of AIDS-related public policy. In the early 1980s, a group of researchers and scientists including Mathilde Krim, Ph.D., then a researcher at New Yorks Memorial Sloan-Kettering Cancer Center, formed an informal study group to investigate the condition that came to be known as AIDS. In 1983, Dr. Krim, Dr. Joseph Sonnabend, Michael Callen, and several others launched the New York-based AIDS Medical Foundation. In Los Angeles, Dr. Michael S. Gottlieb and Elizabeth Taylor spearheaded the creation of the National AIDS Research Foundation. The two organizations merged in September 1985 to become american foundation for AIDS Research (amfAR). The merged organization was launched with a $250,000 contribution from Rock Hudson shortly before his AIDS-related death in October 1985. Charity Watch rates Foundation for AIDS Research a "B" grade.
