She was the first lesbian member of the original Mattachine Society of Washington, D.C. She was Editor of “The Homosexual Citizen”, the Mattachine monthly, under the nom de plume Lilli ‘Hansen’. (No one used their real names then.) Lilli Vincenz’ archive, more than 10,000 items, is now available to researchers, students and the media at the nation’s Library. Lilli deserves our thanks for this gift… and deep appreciation for her activism over decades. The Library of Congress has done amazing work organizing the materials into more than 30 boxes.
