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 started working at the Geodetic Institutein 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 Technical University of Charlottenburg , in 1902 he was appointed professor and in 1911 head of department 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 .
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 independently participate in 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 used the boiling thermometer to determine heights in the Giant Mountains in 1894carried out. 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 about Gauss and Kant in the magazineWeltall 1929 two articles that appeared again in the Göttingen-Mitteilungen of the Gauss Society in 1969.
