Friedrich Ernst DornFriedrich Ernst Dorn (1848, Guttstadt-1916, Halle) was a German physicist who discovered radon. Additional recommended knowledgeIn 1885, at Halle University, Ernst Dorn took over the position of personal ordinarius professor for theoretical physics from Anton Oberbeck. Since Dorn was already an ordinarius professor [1], he was allowed to assume the title so as to not appear as having been demoted. [2] In 1895, Dorn succeeded Hermann Knoblauch at Halle as the ordinarius professor for experimental physics [3] and director of the physics institute. Dorn’s previous duties were taken over by Karl Schmidt, who had been a Privatdozent and was called as an extraordinarius professor for theoretical physics. [4] In 1900 Dorn discovered radon. He was studying the natural radioactive decay of radium, trying to put together details about what was happening to the mass when he detected the presence of a radioactive gas. Dorn initially called the gas "radium emanation". The gas was later called "niton", and, in 1923, it became "radon". Named after "the element radium", the name niton comes from the Latin word "nitens", meaning "shining". Friedrich Dorn is no longer alive[citation needed]. Bibliography
