Lutz D. Schmadel

Lutz Dieter Schmadel (2 July 1942 – 21 October 2016) was a German astronomer and a prolific discoverer of asteroids, who worked at the Astronomisches Rechen-Institut (ARI) of the University of Heidelberg.

His special interest was the astrometry of minor planets. Among his numerous discoveries were the three main-belt asteroids 8661 Ratzinger, 10114 Greifswald, and 11508 Stolte.

He was the author of the Dictionary of Minor Planet Names, a reference book containing information about the discovery and naming of 12,804 asteroids (March 2006). One asteroid 2234 Schmadel, discovered in 1977, was named in his honor. The asteroid 8811 Waltherschmadel was named for his father, Walther Schmadel (1902–1944), who died at the Eastern Front near Stalingrad during World War 2.
