Wilhelm Hedick

from Wikipedia, the free encyclopedia

Wilhelm Hedick (born April 4, 1838 in Belecke , Westphalia; † January 2, 1897 ) was a teacher and pioneer in sound recording.

At Easter 1863 he entered the Realschule in Düsseldorf as a test candidate, was a provisional teacher from autumn 1864 and a full teacher at the Realgymnasium in Cologne from October 1, 1865. Around Easter 1868 he was appointed director of the higher school in Venlo and later he was director of the Rijks Hogere Burgerschool (HBS, higher imperial citizen school) in Tilburg - Breda .

On March 6, 1888, he was granted patent no. 42471 (Brit. Pat. 569/88) in Germany for “... a device for recording acoustic and electrical waves by means of gas or dust jets which ... by telephone-like Device can be hurled longitudinally vibrating against a belt in order to generate writing, as well as reproduction ... with the help of the generated writing ”. This was similar to that of Charles Sumner Tainter (1854–1940) and was refined around 1909 by Ernst Walter Ruhmer .
