(8811) Waltherschmadel Main-belt Asteroid
Discovered on 20 October 1982 by L. G. Karachkina at Nauchnyj.
Named in memory of Heinrich Erwin Walther Schmadel (1902-1944), journalist and editor-in-chief of several German newspapers. He was killed in World War II in Russia near Stalingrad. His story is only an example of the common tragedy between Germans and Russians. There are thousands of people who never saw their fathers. Among these is Walther's son, astronomer Lutz D. Schmadel. This planet is a sign of understanding, friendship and forgiveness for us all.Naming citation (19990728/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
