Description
Howard Atwood Kelly (1858-1943), a graduate of the University of Pennsylvania Medical School, served as the first professor of gynecology and obstetrics at the Johns Hopkins University in Baltimore. He used radium to treat uterine hemorrhages and fibroid tumors. And he acquired this gold leaf electroscope, ca. 1921, and used it to calibrate gamma radiation from a radon glass bulb by comparison with a standard (50 milligrams of radium sulphate sealed in glass).
