Walter Hans Gustav Großmann (born March 6, 1897 in Norden ; † October 13, 1980 in Hamburg ) was a German geodesist . Until his appointment as professor of geodesy at the Technical University of Hanover in 1943, Großmann was director of the Reich Office for Land Survey.

Life

The son of the daughter school teacher Rudolf Adolf Großmann and Johanna Gerhardine Diederike, geb. Müller, attended the humanistic high school in the north . He took part in the First World War as a volunteer. After the operations on the Eastern and Western Fronts, in which he was shot in the lung, he was released in January 1919 as a lieutenant in the reserve with the Iron Crosses I and II. In 1919/20 he did an internship at the land registry office of the city of Norden and then began studying geodesy and cultural engineering at the Agricultural University in Bonn . During his studies he became a member of the Association of German Students in Bonn . From 1922 he worked for the Prussian land registry administration in East Frisia and passed the second state examination in 1926. In 1928 he was seconded as an assistant to the Institute for Surveying at the Technical University of Berlin and finished his studies in 1931 as a graduate engineer. In the same year he married Ilse Stackfleth in Rathenow . In 1932 Großmann received his doctorate from the Technical University of Berlin as Dr.-Ing. with a thesis on the reduced length of the geodetic line and then became a scientific assistant at the Prussian Geodetic Institute in Potsdam, where he dealt with questions of ellipsoidal geodesy and conformal mapping.

From 1932 to 1935 he was also the managing director of the Advisory Board for Surveying and then became a consultant for questions relating to vocational training and geodetic science at the Reich Ministry of the Interior.

In 1937 he completed his habilitation at the Technical University of Berlin, where he was given a teaching position. From 1938 he set up the main surveying department VI in Hamburg . In 1941 he was transferred to the Reichsamt für Landesaufnahme in Berlin , where he took over the management of the central department and, from 1942, the trigonometric department. In 1942 he became director of the Reich Office.

In 1942 he initially took over the geodetic chair at the Technical University of Hanover, where he became full professor for geodesy and director of the geodetic institute the next year.

Großmann was director of the Geodetic Institute of the Technical University in Hanover from February 1, 1943 and was its rector from 1950 to 1951 . In 1965 Großmann was awarded the Helmert commemorative coin from the German Association for Surveying . In 1967 he was awarded the Federal Cross of Merit by the then Federal President Heinrich Lübke, among other things for the comprehensible representation of land surveying and land registry . From 1959 he was a full member of the Braunschweig Scientific Society .

In honor of Großmann, the Walter Großmann Prize is awarded to graduates of the Gottfried Wilhelm Leibniz University in Hanover who have completed the surveying course with diploma theses with above-average ratings.
