First among the distinguished pupils of Gauss may be mentioned August Ferdinand Mobius 1. He studie d at Leipzig, Halle, and Gottingen, first giving his attention to law, but through the influence of Gauss he finally decided to devote himself to mathematics and astronomy. He became a Privatdozent at Leipzig in 1815 and in the following year was made pr ofessor 2 of astronomy. The observatory having been built after his plans (1818-1821), he was made the first director. While his chief writings were on astronomy, he contribut ed in a very important manner to the theory of modern geometry 3.
