To mark World AIDS Day we’re sharing this film clip from the 1976 promotional film Middlebury College, a Chance to Grow which profiled Political Science major and student activist Mario Cooper. After graduating in 1977, Cooper went on to earn a law degree and became a key figure in HIV/AIDS advocacy after becoming HIV positive and witnessing the disproportionate effects of the disease in the African American community.

Though it may have once seemed like an unassuming profile of a passionate student, the clip can now be appreciated as an early view into the work of a determined activist who would later become a prominent figure in civil rights and AIDS advocacy movements. The footage and narration also poignantly show Cooper enjoying college life and friendships in a time before the AIDS epidemic changed his life and that of those around him.

Mario Cooper died in 2015 while in hospice care in Washington, D.C. His New York Times obituary can be read here, and a tribute to his work as an activist can be read on POZ, the social network for people living with or affected by HIV/AIDS.
