Dr. Alan L. Hart (1890 – 1962)

Dr. Hart was an American physician, radiologist, tuberculosis researcher, writer and novelist. In 1918, he was one of the first trans men to undergo hysterectomy and gonadectomy in the United States and lived the rest of his life as a man.

He pioneered the use of X-Ray photography in tuberculosis detection. Dr. Hart was instrumental in developing tuberculosis screening programs at the time that TB was the largest disease killer in the US. Dr. Hart’s efforts with screening programs saved thousands of lives. Utilizing an X-Ray system Dr. Hart developed, doctors managed to cut the tuberculosis death toll down to one-fiftieth from previous levels.
