Karl Heinrich Hecht

from Wikipedia, the free encyclopedia

Karl Heinrich Hecht (born February 4, 1880 in Magdeburg , † October 25, 1961 in Kiel ) was a German physicist .

Life

Hecht studied mathematics and physics at the Albertus University in Königsberg and received his doctorate there in 1903. After working at Siemens and Halske and as a research assistant - from 1904 to 1908 - at the normal calibration commission in Berlin-Charlottenburg, he joined the April 1908 in the service of the Kiel company "Neufeld & Kuhnke Elektrotechnische Fabrik", which had placed a corresponding job advertisement in the bulletin Annalen der Physik . Right from the start, Hecht dedicated himself to the subject of underwater sound technology, but the first attempts made it clear that basic research had to be carried out in this area. In his personal report Die Zeit bei Neufeld & Kuhnke (1908-1911) , which is printed in his memory report 'The history of electroacustic up to 1941', Hecht describes the challenges he faced at the time. His practical-experimental attempts got stuck in the early stages and the tasks were unsolved for the time being. Then he came across patents from Alard du Bois-Reymond and Hans Görges, which related to electromagnetic transmitters for the same purpose. In 1908, Hecht, coming from Kiel, visited the patent attorney and engineer Alard du Bois-Reymond in Berlin. Their meeting marked the beginning of a close collaboration and later friendship. When Neufeld & Kuhnke founded a subsidiary in Kiel in 1911, Signalgesellschaft mbH, Hecht and du Bois-Reymond were on the supervisory board there. Hecht later described the meeting with Hans Usener, Alard du Bois-Reymond and Walter Hahnemann as “a very good fortune of fate”, because, according to Hecht, these had a very large part in his scientific and practical successes. Hecht describes Alard du Bois-Reymond in his 'History of Electroacustic up to 1941' as a scholar and a universal genius. In 1915, the Kieler Signalgesellschaft established a branch for underwater scarf tests in Plön, in the Großer Plöner See. In 1926, Hecht founded the Electroacustic company with shareholders Gerhard Schmidt and Rudolph , in which he worked until his death.
