Lilli Vincenz, 75, a D.C.-area resident who worked with Frank Kameny as a pioneer in the gay rights movement beginning in the early 1960s, has donated to the Library of Congress some 10,000 papers, photographs, 16-mm films and memorabilia collected over a period of 50 years.

In a statement released on July 25, the Library of Congress said the papers and other items, which document Vincenz’s “personal biography and the larger gay rights movement,” will be available to researchers and the public once the materials are organized and catalogued.

The statement notes that Vincenz was one of the first lesbian members of the Mattachine Society of Washington, D.C., the nation’s first full-fledged gay civil rights organization co-founded by Kameny and then D.C. gay activist Jack Nichols. It says Vincenz became the first editor of the organization’s newsletter, The Homosexual Citizen.

In that capacity, Vincenz and lesbian activist Nancy Tucker co-founded in 1969 an independent gay newspaper as a spinoff of the Mattachine newsletter called the Gay Blade, which later evolved into the Washington Blade

“She marched in the historic [gay rights] picket of the White House on April 17, 1965, participated in annual July 4th gay rights demonstrations in Philadelphia, and was part of the delegation that met with U.S. Civil Service Commission officials in 1965 to discuss the continued federal ban on hiring homosexuals,” the Library of Congress statement says.

“Vincenz was also an early member of the Daughters of Bilitis, a national lesbian rights organization, wrote a bi-weekly column for the New York-based Gay magazine, and was interviewed often by the media with other lesbian leaders,” the statement says.

The Library of Congress statement says the donation of Vincenz’s papers was made through her agent, Charles Francis, the co-founder of the Kameny Papers Project, which donated Kameny’s papers to the Library of Congress in 2006.

Vincenz and her partner Nancy Davis live in Arlington, Va.
