Winkelmann was a German physicist and director of the Physical Institute at Jena. His main research was conducted on thermal conduction in gases, specific warmth in liquids, and abnormal dispersion. He also discovered important characteristics of the X-Ray with Otto Schott (trans. and summ. from German Wikip.). The Handbuch der Physik was a prestigious encyclopedia that continued to be published at least to 1990.
