Leo Pungs

from Wikipedia, the free encyclopedia

Leo Wilhelm Julius Pungs (born August 6, 1883 in Moscow , † February 16, 1979 in Braunschweig ) was a German electrical engineer and radio pioneer .

Life

Leo Pungs was the son of a factory owner from the Lower Rhine region in Moscow and a student at the St. Michael School there. After his parents returned to Germany, he studied electrical engineering at the Technical University of Darmstadt until 1906 . After passing the main diploma examination, he stayed three years as an assistant at Erasmus Kittler . Then he went into industry. In 1910 he designed three-phase motors for Brown, Boveri & Cie in Baden , Switzerland. He then went back to Darmstadt and received his doctorate in 1912 under Waldemar Petersen with his thesis: The dielectric behavior of liquid insulating materials at high alternating voltages .

He then started working as a development engineer at C. Lorenz AG in Berlin, which had developed into a competitor to Telefunken in radio technology since 1906, when it acquired the rights to Valdemar Poulsen's arc transmitter . During the First World War he served in the Navy, headed the radio laboratory and worked with Hans Harbich on direction finding and navigation equipment.

After the end of the war he became laboratory manager and authorized signatory at C. Lorenz AG . As early as 1913, he had developed a method for amplitude modulation of undamped vibrations using controlled iron chokes. The Pungs throttle named after him was an important component in the development of radio transmitters and was also used in the broadcast of the first test programs via the broadcasting systems in Königs Wusterhausen and Eberswalde in 1920 and 1921. Under his direction, a radio telephone connection was also established between Copenhagen and the island of Bornholm. Together with Felix Gerth he developed the "Hapug modulation", an energy-saving modulation method.

In 1927 he founded the second institute for low-voltage technology in Germany at the Technical University Carolo-Wilhelmina in Braunschweig , which he headed until 1954. During the Second World War he was back in the Navy and dealt with antenna technology, but also the camouflage of fixed and moving targets against radio-based detection and location methods (radio measurement technology, or modern term radar ).

From 1949 to 1953 Pungs was chairman of the engineering class of the Braunschweigische Wissenschaftlichen Gesellschaft .

Leo Pungs was married to Anna-Lucia Pungs geb. Drewa (1883-1979).
