Lewy described neuronal inclusions in the brain of patients who had suffered from Paralysis agitans (i.e., Parkinson's disease). Later, these findings became the so-called "Lewy bodies." Exiled from Germany in 1933, Lewy spent a year in England before emigrating to America with his wife Flora where he worked in the Department of Neurosurgery, Pennsylvania University Hospital. Between 1943 and 1946, he was a Lieutenant Colonel in the U.S. Army and a consultant in neurology to the Surgeon General. He returned to Penn after the war. In 1949, he travelled to Argentina to learn the Hortega method, a special histological silver staining technique, which he successfully applied for the diagnosis of brain tumors.
