Max Gasser (geodesist)

from Wikipedia, the free encyclopedia

Max Gasser (born February 13, 1872 in Sulzberg (Oberallgäu district) , † March 28, 1954 in Munich ) was a German photogrammeter and geodesist . He is considered a pioneer in aerial photography .

Life

Max Gasser was born in Sulzberg in the Allgäu in 1872 as the son of a sawmill owner and the daughter of a brickworks owner.

He studied in Munich at the university and at the Technical University , where he graduated as a surveying engineer in 1896 . From 1900 Gasser worked at the Geodetic Institute of the Technical University until he was awarded a Dr. phil. PhD . At the request of the Technical University of Darmstadt , he completed his habilitation there in 1907 for geodesy and astronomical positioning . From 1909, in addition to his lectureship in Darmstadt, he was also department head of the Hahn optical company in Kassel .

His research areas included photogrammetry and stereoscopy , in other words, stereophotogrammetry .

In order to be able to undertake a test flight to record maps with a zeppelin , he contacted the inventor of the aircraft, Ferdinand von Zeppelin , and achieved a test flight on October 20, 1909. Other flights followed in addition to zeppelins in Parseval airships and airplanes. In the same year he founded the forerunner of the German Society for Photogrammetry, Remote Sensing and Geoinformation in a course for stereophotogrammetry by Carl Pulfrich . In the following six years of research he made significant progress in the latter area and was awarded several patents in 1915 . However, he was unable to profit financially from this, as the patents were militarily blocked and confiscated due to the First World War . In 1914 he was already teaching 18 officers how to evaluate aerial photographs.

Even after the war, Gasser remained commercially unsuccessful, although he was able to win a patent dispute in court. In 1919 he moved to Kalkberge near Berlin , in 1922 he married the farmer's daughter Maria Haslauer in Berlin-Schöneberg . In 1936 Gasser returned to Bavaria and from then on lived in Munich- Pasing until his death in 1954 .
