Who Was Alan L. Hart? 

Alan L. Hart (1890–1962) was an American physician, radiologist, researcher, and writer. He was also one of the first known transgender men in the United States to medically transition. Hart lived at a time when both tuberculosis and transgender identities were poorly understood, yet he made lasting contributions to medical science. 

What Did Alan L. Hart Do? 

Alan L. Hart was a medical innovator who helped improve the early use of X-ray technology to detect tuberculosis (TB), one of the deadliest diseases of the early 20th century. He strongly promoted the use of radiology to diagnose TB earlier, which helped prevent its spread and saved lives. 

Hart worked in public health, wrote medical research papers, and helped modernize how doctors identified and treated infectious disease. In addition to his scientific work, he wrote novels and essays that reflected his experiences in medicine and society. 

How Did Alan L. Hart Impact LGBT History? 

Alan L. Hart is an important figure in transgender history. With the support of doctors, he medically transitioned in 1917 and lived openly as a man for the rest of his life. At a time when transgender people faced extreme discrimination and misunderstanding, Hart’s ability to build a successful medical career was remarkable. 

His life demonstrates that transgender people have always existed in science and medicine, even when they were forced to remain private about their identities to stay safe.
