Gay Rights Pioneer Frank Kameny To Lie In State; House Declared Historic

WASHINGTON -- Gay rights pioneer Frank Kameny, who died last month at age 86, will lie in state on Thursday in the Carnegie Library on Mount Vernon Square, part of an on-going memorial for the man whose firing from a government job in the 1950s helped sparked a movement.

While the public viewing of Kameny's flag-draped coffin is not a formal public memorial service, it is "intended to invite all grieving friends and neighbors to remember and honor his life and his legacy," according to organizers. A public memorial service is being planned for a later date.

Thursday's viewing will start at 3 p.m. and conclude at 8 p.m. D.C. Mayor Vincent Gray will offer remarks between 6 p.m. and 7 p.m. according to his public schedule.

As The Washington Blade reports, the National Park Service announced on Wednesday that Kameny's residence is now listed on the National Register of Historic Places, a place, according to an agency statement, that "served as a meeting place, archives, informal counseling center, headquarters of the Mattachine Society, and a safe haven for visiting gay and lesbian activists."
