Alan L. Hart, American physician and author (died 1962)

Alan L. Hart
Alan L. Hart was an American physician, radiologist, tuberculosis researcher, writer, and novelist. Hart pioneered the use of X-ray photography in tuberculosis detection; he worked in sanitariums and X-ray clinics in New Mexico, Illinois, Washington, and Idaho. For the last 16 years of his life, he headed mass X-ray programs that screened for tuberculosis in Connecticut. X-rays were not regularly used to screen for tuberculosis prior to Hart's innovation, and are still used as a gold standard today, which has led researchers to believe that he has saved countless lives.
