Michael Callen (April 11, 1955 - December 27, 1993) was a singer, songwriter, composer, author, and AIDS activist. He was a significant architect of the response to the AIDS crisis in the United States. First diagnosed with "Gay related immune deficiency" (GRID) in 1982, Callen quickly became a leader in the response to the epidemic, coining the phrase "people with AIDS (PWAs)" in contrast to the then current "AIDS victims".
