Heinrich Rauschelbach

from Wikipedia, the free encyclopedia

Heinrich Rauschelbach (born October 13, 1888 in Hoya ; † December 17, 1978 in Mölln ) was a German astronomer and precision mechanic .

Life

In 1916 he was employed at the observatory as a successor to Otto Kohl as an astronomical assistant. In 1920 he placed his friend Walter Baade as an assistant at the Hamburg observatory . In 1924 he moved to the Deutsche Seewarte in Hamburg. Here he developed a measuring device for the tidal current around 1929 .

Shortly before the Second World War, he had the largest tide calculator built by the Mechanoptik-Gesellschaft für Präzisionstechnik, Erich Aude & Ernst Reipert . It was requested in 1935 by the Reich Ministry for Seafaring and was installed in the naval observatory in Wilhelmshaven in 1938. 62 partial tides are used, which are summed up with a 38 m long metal strip made of a temperature-stable special alloy. The device is 7.5 m long, 2 m high and weighs approx. 7 t.
