Walter Rogowski

Walter Johannes Rogowski (born May 7, 1881 in Obrighoven near Wesel , † March 10, 1947 in Aachen ) was a German electrical engineer .

life and work

From 1900 he studied physics at the Technical University in Aachen with Arnold Sommerfeld . After completing his intermediate diploma in 1902, he went to the Danzig Technical University . After graduating in 1904 he worked there as an assistant and received his doctorate in 1907 . In 1909 he became a research assistant at the Physikalisch-Technische Reichsanstalt in Berlin, where he did research in the fields of heavy current technology , telecommunications technology and electrophysics. Here he made the Rogowski reel known in 1912 . The Rogowski profile , a special shape for electrodes , also goes back to his work. He is the founder (1913) and was editor of the journal Archiv für Elektrotechnik , which appears today under a new title as Electrical Engineering in Springer-Verlag .

After the First World War, he moved to Jena University as a professor of technical physics in 1919 . Just one year later, Rogowski was appointed professor for general and theoretical electrical engineering and director of the institute for electrical engineering at the Technical University of Aachen. A high-performance cathode-ray oscillograph was developed under his direction , with which the temporal course of a traveling wave was experimentally demonstrated for the first time in 1925.

From 1927, like Eugen Flegler and Rudolf Tamm , he dealt with the question of increasing the intensity of an electron beam deflection by inserting a second short coil between the cathode and anode screen in 1927. This should concentrate the beam emanating from the cathode on the small opening of the anode screen, so that the writing beam emanating from it received the highest possible current strength.

In the same year, the Norwegian Rolf Wideröe obtained his doctorate with a thesis on an electric particle accelerator. The publication in the Archives for Electrical Engineering gave Ernest Lawrence the idea of the cyclotron .

Although Rogowski had joined the NSDAP in 1933 , he largely abstained from politics and instead focused on his research. When he wanted to leave the Technical University in Belgium in 1944, he was arrested by the Gestapo at the instigation of his Rector Hans Ehrenberg . After a short preventive detention, however, he was able to resume his regular work in Hannoversch-Münden , where his institute and others had been relocated. Despite his membership in the NSDAP, he was the only member of the Faculty of Mechanical Engineering who remained in office after the end of the war and was confirmed by the Allied military government and shortly afterwards appointed dean of his faculty.

Rogowski Institute at RWTH Aachen

For his services, Rogowski was awarded a Dr. hc of the TH Darmstadt and in 1938 made an honorary member of the Association of German Electrical Engineers and in 1947 as the namesake of the Institute for Electrical Engineering of the RWTH Aachen.
