X–rays are sometimes known as Röntgen rays (sometimes anglicised as Roentgen rays) after Wilhelm Röntgen, the German–Dutch physicist who discovered them in 1895.
Röntgen was born in 1845 in Remscheid, in Germany, to a Dutch mother and a German father. He attended school in Utrecht (Netherlands) and university in Zurich (Switzerland). He then became a lecturer at the University of Strasbourg (which was then in Germany). In 1895 he was working at the University of Würtzburg, and he moved to the University of Munich in 1900. He died in Munich in 1923.
