Louis G. Sullivan (b. Milwaukee, 1951; d. San Francisco, 1991) was a writer, activist, typesetter, trans historian and ground breaking queer activist. Sullivan began writing his life in diaries as an adolescent and continued until his death from AIDS complications. The first publicly gay trans man to medically transition, Lou meticulously journaled his experiences (romantic, lascivious, challenging, quotidian, poetic, political). Sullivan left 8.4 cubic feet of archival material from his life and studies to the GLBT Historical Society in San Francisco, of which he was a founding member.
