Wilhelm Holtz (born October 15, 1836 in Saatel near Barth , Western Pomerania , † September 27, 1913 in Greifswald ) was a German physicist and inventor of the Holtz machine named after him .

Life

Wilhelm Holtz was the sixth son of the manor owner Adolf Christian Ludwig Holtz (* June 15, 1797 in Suckow near Güstrow, † May 8, 1838 on Saatel) and his wife Regina Ilsabe Lübke (* 1798 as the daughter of the mill owner Andreas Lübke from Stralsund , † November 30, 1869).

Between 1857 and 1862 he studied physics and other natural sciences in Berlin , Dijon and Edinburgh . Afterwards he worked in Berlin in particular with experiments on electricity .

In 1865 Holtz invented the influenza electrifying machine named after him . After a few more discoveries in this area, a nervous disease forced him to stop his scientific work for a long time.

Holtz invented the valve or double funnel tube in which the electron current only flows through one or the other channel of the tube, depending on the polarity of the connection voltage. This tube was the first to rectify electricity and is the basis for the Graetz rectifier tube .

In 1869 he received his doctorate at the University of Halle and later received a position as an assistant at the University of Greifswald . Here Holtz completed his habilitation in 1881 and worked as a private lecturer before he was appointed professor of physics in 1884 .

Wilhelm Holtz retired in 1910 and died on September 27, 1913 in Greifswald.
