Andreas Galle

from Wikipedia, the free encyclopedia

Andreas Wilhelm Gottfried Galle (born June 22, 1858 in Breslau ; † May 8, 1943 in Potsdam ) was a German geodesist .

Life

The father, Johann Gottfried Galle , was a well-known astronomer . Andreas Galle attended the Maria-Magdalenen-Gymnasium in Breslau from 1867 . After graduating from high school in 1877, he studied mathematics and natural sciences in Göttingen , Breslau and Berlin . From 1880 to 1883 he was an assistant at the observatory of the Wroclaw University, which his father directed. He received his doctorate in 1883 with the dissertation on the calculation of proximities of asteroid orbits . In 1884 he began his work at the Geodetic Institute in Potsdam as an assistant. In 1894 he became an observer there. In 1895 he married. The marriage had a daughter. From 1900 to 1910 Galle taught geodesy as a private lecturer at the Technische Hochschule Charlottenburg , in 1902 he was appointed professor and in 1911 department head at the Geodetic Institute (GI), to which he had been a member for almost forty years. In 1919 he was elected a member of the Leopoldina .

Services

The astronomical work at the GI was headed by Carl Theodor Albrecht since 1873 . As his close colleague, Galle took part in his observations and calculations. But soon he was able to contribute independently to investigations of length differences , latitude observations , azimuth measurements as well as zenith distance measurements and gravity measurements . Pole height determinations were used to determine fluctuations in the earth's axis and he carried out height determinations in the Giant Mountains in 1894 with the boiling thermometer . The results of this work have been published in comprehensive treatises of GI, such as: the latitude of Potsdam (1898) and after extensive investigations in the resin : deflections in the Harz and its surrounding area (1908) and The geoid in the Harz (1914). In addition to his official contributions, Galle has also written numerous private articles. His scientific fields of work were diverse. He dedicated several writings to the Little Planet from 1885 to 1890 and calculated ephemeris for them . He published two articles about Gauß and Kant in the magazine Weltall in 1929, which appeared again in 1969 in the Göttingen-Mitteilungen of the Gauss Society.
