The AIDS community mourned the loss of two prominent leaders last week. Keith Cylar, co-founder and co-President of Housing Works, died early Monday morning of cardiomyopathy, a condition that enlarges the heart. Founded in 1990, Housing Works has become the largest community-based AIDS services organization in the nation, providing housing, healthcare and advocacy. An active member of ACT-UP from 1987 to 1995, Cylar also served on the boards of the Harm Reduction Coalition and the National AIDS Housing Coalition during his 20 years living with HIV. Also last week, friends and colleagues celebrated the life of AIDS activist Joseph Bostic, who died March 18. A founder and the co-director of the New York City AIDS Housing Network, Bostic spent decades as a civil rights and economic justice activist before his career was eclipsed by a 17-year prison sentence. Homeless and HIV-positive upon his release from Rikers Island in 1999, Bostic continued his social justice career. He served as the 2002-2003 Community Co-Chair for the NYC HIV Health and Human Services Planning Council and founded the Parolee Human Rights Project. [4/12/04]
