29227 Wegener           Discovered 1992 Feb. 29 by F. Borngen at Tautenburg.
German scientist Alfred Wegener (1880-1930) created the theory of continental drift, which explained even the climates of prehistoric times and was verified later by geotectonics. A participant in several polar expeditions, he perished on the Greenland ice sheet.
