Dr. Alan Hart helped pioneer the use of chest X-rays to diagnose tuberculosis. Hart was married to a woman and practicing medicine in San Francisco in 1918 when he was outed as a trans man by a former colleague. Dr. Hart was chased out of town on the back of headlines like “Girl Poses as Male Doctor in Hospital" (he was not posing, of course) and spent much of his life moving from town to town to escape various forms of transphobia. Hart was also a novelist, and wrote of one of his characters, "When it came to outrunning gossip he found he couldn't do it," which was Hart's experience as well—he moved seven times in nine years all around the U.S. in search of safety, but it always proved fleeting. He did manage to get a graduate degree in radiology, though, and helped show how chest X-rays could show very early signs of tuberculosis, thus allowing patients the opportunity to rest and get adequate nutrition sooner, which contributed to better outcomes. Chest X-rays continue to be an essential diagnostic tool; mobile chest X-ray machines that can be carried via backpack now serve rural communities, so Hart's popularization of this diagnostic method continues to save lives.
