Reinhard Hugershoff

from Wikipedia, the free encyclopedia

Carl Reinhard Hugershoff (born October 5, 1882 in Leubnitz , Amtshauptmannschaft Zwickau ; † January 24, 1941 in Dresden ) was a German geodesist and aerial photography pioneer as well as a professor at the Technical University of Dresden .

Life

Hugershoff's family came from the south-west of Saxony. His mother was the daughter of a Leubnitzer head conductor, the grandfather on his father's side was music director in Chemnitz and Zwickau. The family came to the Saxon capital through the work of their father Albin Huggershoff (1855–1910) as a mechanical engineer in the Dresden military waterworks .

After graduating from high school in Dresden-Neustadt , Hugershoff studied geodesy at the TH Dresden from 1903 to 1906 until he graduated and received his doctorate in 1907. In 1907/09 he took part in the 2nd Frobenius expedition to Inner Africa. There he made route recordings, astronomical and hydrographic measurements. From 1910 he taught mathematics , surveying , meteorology , photogrammetry at the Tharandt Forest Academy and the TH Dresden, 1910 as a private lecturer , 1911 as an associate professor , in 1912 as a professor in Tharandt, 1931 as a professor at the TH Dresden. During the First World War he promoted the military determination of target points and planning documents from photographic recordings of earth and later aerial positions. He played a major role in the new creations of photogrammetric and geodetic equipment from 1920–31. From 1931 he was also a research assistant at the Carl Zeiss Jena company . In 1940/41 he was transferred to the civil engineering department of the TH Dresden as professor of surveying and photogrammetry. Hugershoff had been a member of the NSDAP since 1930 and in November 1933 he signed the confession of the German professors to Adolf Hitler . With the close-up picture measurement he tried to support race research .

Inventions

Hugershoff's inventions include terrestrial recording chambers , aerial photo chambers for plates and film tapes, indexing mechanisms, fully automatic row formers and overlap regulators for aerial photographs, especially the universal evaluation device Aerokartograph (1926), which made it possible for the first time to connect entire rows of images ( aerotriangulation ). Special structures were the stereometric measuring table for continuous recording layer lines in sight of land, a selbstreduzierendes tachymeter for distance and height difference measurement, an evaluation on the principle of double projection (Aero Simplex) as a precursor of the multiple projection apparatus Multiplex (1932), which in the Second World War an important role played and long formed the basis of card production in many countries.

In honor of Hugershoff's achievements, Hugershoff Cove in Antarctica today commemorates him.
