Immo Appenzeller (born May 13, 1940 in Urach (Württemberg) ) is a German astronomer .

Appenzeller studied physics at the University of Tübingen from 1959 and from 1961 physics and astronomy at the University of Göttingen , where he received his doctorate in 1966 . From 1964 was at the Yerkes Observatory of the University of Chicago and from 1967 assistant in Göttingen. After completing his habilitation in 1970, he was a private lecturer there and an adjunct professor in 1974. In 1972 he was visiting professor at the University of Tokyo .

Appenzeller researched both theoretically, for example on star models, and in the development of astronomical instruments. He was significantly involved in the European Very Large Telescope at ESO ( European Southern Observatory ) in Chile (he was project manager for the FORS instrument, two of which are installed as a combined camera and spectrograph at the VLT), where he explored early galaxies, among other things. Further areas of interest are massive, bright stars, active galaxies and quasars , cosmic X-ray sources.

Since 1979 Appenzell has been an "External Scientific Member" of the Max Planck Institute for Astronomy in Heidelberg. In 2002 he received the Gay Lussac Humboldt Prize . In 1991 the asteroid (2373) Immo was named after him. From 1994 to 1997 he was Secretary General of the International Astronomical Union . He is a member of the Heidelberg Academy of Sciences . For 2015 he was awarded the Karl Schwarzschild Medal .
