JENNIE JUNE (b: 1895–d:1922) was a pseudonym of an American writer from the Victorian and Edwardian era known for advocating for the rights of people who did not conform to gender and sexual norms.

June was one of the earliest transgender individuals to publish an autobiography in the United States. Although June expressed a lifelong desire to be a woman, June consistently used he/him pronouns in reference to themselves in their own writing. June wrote of feeling like a combination of male and female, and of their practice of alternating between these two gender expressions.

They published their first autobiography, The Autobiography of an Androgyne, in 1918, and their second, The Female-Impersonators, in 1922. June also wrote an unpublished third autobiography in 1921, which historians discovered in 2010. June’s stated goal in writing these books was to help create what they would have wanted for themselves: an accepting environment for young adults who do not conform to gender or sexual norms. They also wanted to prevent them from committing suicide. Around 1895, June also created an organization for the rights of androgynes, together with others like themself; most if not all members were noted by June as being ultra-androgynes.

June also wrote under the pseudonyms of Earl Lind and Ralph Werther, which are sometimes incorrectly mistaken for birth names. June’s birth and legal names are not certain and have been considered to be lost to history. Queer history researcher Channing Gerard Joseph believes that June was most likely the writer and journalist Israel Mowry Saben (1870–1950), an early advocate for gender and sexual diversity.

Currently, historians do not certainly know the date of June’s life and death. Channing Gerard Joseph theorizes that June was likely Mowry Saben (1870–1950), the writer and journalist. Saben was born in Uxbridge, Massachusetts, into a prominent family, and had a younger sister, Jennie May. They graduated from Harvard University, Oxford University, and Heidelberg University. They died in San Francisco in 1950.

June left instructions for the creation of a memorial plaque. June wanted the plaque to be placed on the Grand Street facade of a new police building, near the site of their debut, where they had first taken the name Jennie June. A police building could be considered an intriguing choice, given the police harassment June and their friends experienced.
