Herculine Barbin (November 8, 1838 – February 13, 1868) was a French intersex person who was assigned female at birth and raised in a convent, but was later reclassified as male by a court of law, after an affair and physical examination. In 20th-century medical terms, she had male pseudohermaphroditism. She is known for her memoir, Herculine Barbin, which was published and studied by Michel Foucault.
