or Wilhelm Conrad Roentgen born March 27, 1845, Lennep, Prussia died Feb. 10, 1923, Munich, Ger. German physicist. He taught at the Universities of Giessen (1879-88), Würzburg (1888-1900), and Berlin (1900-20). In 1895 he discovered rays that did not exhibit properties such as reflection or refraction and mistakenly thought they were unrelated to light. Because of their mysterious nature, he called them X rays. He later produced the first X-ray photographs, showing the interiors of metal objects and the bones in his wife's hand. He also did important research in a wide variety of other fields. In 1901 he was awarded the first Nobel Prize for Physics
