2350 von Lude           Discovered 1938 Feb. 6 by A. Bohrmann at Heidelberg.
Named in memory of Heinz von Lude (1914-1974), astronomer at the Astronomisches Rechen-Institut who calculated many preliminary orbits of minor planets. He also studied a fictitious example of 3/1 libration in the restricted three-body problem and was involved with the meridian-circle program at the Heidelberg Observatory.
