Physician, roentgenologist
Isak Robinsohn was born in Brody, Galicia, then under the Austro-Hungarian Monarchy. He was the first roentgenologist at the Allgemeine Krankenhaus (General Hospital) in Vienna (a student of professor Holznecht). Robinsohn constructed the first device, the throchtoscop, to scan patients while lying down, and later the tube screen. He also had meaningful achievements in urological roentgenology. The calcification of the pelvic nerves, the so called Robinsohnische Flecken (“Robinsohn Spots”) are named after him. He, among others, also pioneered dental roentgen diagnosis.
