First Edition stated. Baldridge dustjacket art. This copy nicely signed and inscribed by Hart at front endpaper, 'To another of the TB gang - Mrs Breed.' Author's first book. Alan Hart (1890-1962) was a physician, radiologist, tuberculosis researcher and writer/novelist. In 1917-18, he was one of the first trans men to undergo hysterectomy and gonadectomy surgeries, the very first in the United States. In his childhood, he was free to present as male, and his family was overall remarkably accepting for the time. He went back into the closet for his schooling years, though in college he published under male pseudonyms and anonymously in school newspapers and magazines. He underwent surgeries before his first medical internship, and lived the rest of his career and life trying (with varying degrees of success) to keep his pre-transition life a secret from colleagues, patients and friends, living exclusively as a man in society. Hart’s medical career consisted primarily of innovative research into early detection of TB using x-rays, and large-scale implementation of mobile and permanent TB clinics in Idaho and Connecticut, which helped curb the early 20th century epidemic in those states significantly. Hart also found time to be a successful novelist. Aspects of his protagonists are semi-autobiographical, including rare examples of LGBTQ representation in popular fiction, and he is considered a pioneer in medical fiction. Near Fine, some foxing to preliminary and endpapers in very attractive Near Fine dustjacket.
