Richard Schumann

from Wikipedia, the free encyclopedia

Richard Schumann (born May 9, 1864 in Glauchau , † February 2, 1945 in Vienna ) was a German-Austrian astronomer and geodesist .

Live and act

After studying and doing his doctorate in 1888 with Heinrich Bruns in Leipzig, Schumann was initially professor of surveying at the TH Aachen, through the mediation of Friedrich Robert Helmert , and at the same time director of the Central Office for International Earth Surveying until 1909 . During this time he was elected dean of his faculty twice. Subsequently, in 1911, he was appointed professor of geodesy and spherical astronomy at the Vienna University of Technology . In the academic year 1914/15 he was elected rector of the technical university.

In addition to his teaching activities, he made a contribution to the basic surveying of Austria-Hungary and led a. a. high-precision azimuth measurements in the first order network, which could still be used 80 years later in a diploma thesis as zero measurements for geodynamic investigations.

Similar to Karl Friedrich Küstner in Bonn, he dealt with precise studies of the terrestrial polar movement and its periodicity (see Chandler period ).

His successor as geodesy professor was Friedrich Hopfner (1881–1949) in 1936 .

In 1917 he was elected a member of the Leopoldina . For his services, Schumann was awarded a Dr. Ing. E. h. of the TU Berlin and received the Goethe Medal for Art and Science in 1942 .

Schumann, the son of a businessman and great-nephew of Robert Schumann, was married to Erna Jastram. The couple had a daughter and a son.
