Galle was director of an observatory and a university professor in Breslau (Wroclaw, 1851-95).

He also refined the parallax of the sun (8.87″). In 1847, Galle compiled a survey table of the elements of 178 comets for the period from 371 B.C. (with historical references). Using coordinates calculated by Leverrier, he discovered the planet Neptune on Sept. 23, 1846.
