Wilhelm Holtz
Wilhelm Holtz (* October 15, 1836 in Saatel Barth, Pomerania, † September 27, 1913 in Greifswald ) was a German physicist and inventor of the eponymous Holtz machine.
Life
Wilhelm Holtz was the sixth son of the manor owner Adolf Christian Ludwig Holtz ( born June 15, 1797 in Suckow at Gustrow, † May 8, 1838 at Saatel ) and his wife Regina Ilsabe Luebke (* 1798 as the daughter of mill owner Andreas Luebke from Stralsund, † November 30, 1869 ).
He studied 1857-1862 in Berlin, Dijon and Edinburgh physics and other natural sciences. Subsequently, he worked in Berlin, particularly with experiments on electricity.
1865 invented Holtz named after him Influenzelektrisiermaschine. After some further belonging to this area discoveries made him a nervous disorder for a long time, cancel his scientific work for the time being.
Holtz invented valve or double funnel tube in which the electron current depending on the polarity of the supply voltage passes through only one or the other channel of the tube. This tube was the first for rectification of electricity and is the foundation for the rectifier tube according to Graetz.
In 1869 he received his doctorate at the University of Halle and later received a position as assistant professor at the University of Greifswald. Here Holtz habilitated in 1881 and worked as a lecturer before he was appointed in 1884 as professor of physics.
Wilhelm Holtz in 1910 emeritus and died on 27 September 1913 in Greifswald.
