Wilhelm Conrad Röntgen (27 March 1845 – 10 February 1923) was a German experimental physicist who produced and detected electromagnetic radiation in a wavelength range known as X-rays (known as Röntgen rays in many languages). In 1901, Röntgen became the first recipient of the Nobel Prize in Physics "in recognition of the extraordinary services he has rendered by the discovery of the remarkable rays subsequently named after him." The element roentgenium is named in his honor.
