Life

From 1873 Hepperger studied mathematics, physics and astronomy in Innsbruck, Munich, Würzburg and Vienna, passed the teaching examination in 1878 and received his doctorate in Vienna in 1879. In the same year he went to the Vienna observatory, where he became an assistant in 1880. In 1884 he became a private lecturer after his habilitation. From 1891 he was associate professor for astronomy at the University of Graz for 10 years . The chair had just been re-established, the observatory had existed since 1875, before Karl Friesach (1821–1891), Ludwig Boltzmann (1844–1906) and Johannes Frischauf (1837–1924) represented astronomy “on the side”. In 1901 he became a full professor for theoretical astronomy in Vienna. From 1909 to 1928 he was director of the Vienna University Observatory . Although the focus of his work was in the field of classical (positional) astronomy, he also supported spectral analysis as director of the observatory.

He was editor and editor of W. Oeltzen's star catalog (catalog of 26060 stars). He received a prize from the Vienna Academy of Sciences for determining the orbit of Comet Biela . He also wrote an article on orbit determination in the Encyclopedia of Mathematical Sciences .
