D.E.V.I.C.E. is an encyclopedia of terms used by manufacturers of test and measurement equipment. T&M Atlantic created this service to better explain the functionality of instruments it offers, and to highlight the latest developments in the world of measurement equipment. We are using such tools as animation to bring words and pictures to life and to create not just an understanding but also an appreciation for technology that goes into the design of every instrument.

Walter Rogowski (May 7, 1881 in Obrighoven, Germany – March 10, 1947 in Aachen, Germany) was a German physicist who bridged the gap between theoretical physics and applied technology in numerous areas of electronics; the Rogowski coil was named after him.
In 1900, Rogowski began his studies at the RWTH Aachen, under Arnold Sommerfeld, who occupied the Chair for Applied Mechanics. He acquired his Vordiplom in 1902 and went on to study at the Danzig Technische Hochschule, where he was also a scientific assistant. He completed his studies at Danzig in 1904, but stayed on until 1908, when he went to be a scientific assistant at the Physikalisch Technische Reichsanstalt in Berlin, specializing in high current technology, telecommunications technology, and electrical physics. After World War I, Rogowski returned to Aachen, in 1920, and he became an ordinarius professor for theoretical electro-technology and director of the Institute for Electro-Technology. At that time, the institute was in the mining industry building. Rogowski, with his head assistant Eugen Flegler, began to put together a plan for their own building; the draft submission to the Ministry of Education was made by the university in 1923. However, the plan was not tackled until 1925, with inauguration of the generous institute building on October 27, 1929. The original plan proposed to house the entire electrical engineering section in the building. However, during the building phase, it was decided to only house Rogowski’s Institute in it. A main thrust of the institute was to bridge the gap between physics and electro-technology. Work carried out in the institute included general electro-technology, theoretical electro-technology, telecommunications technology, high frequency engineering, electrical discharges in gases, and high voltage technology. The institute was renamed in Rogowski’s honor and became the Rogowski-Institut der RWTH Aachen.
