13977 Frisch           Discovered 1992 Apr. 29 by F. Borngen at Tautenburg.
Austrian zoologist Karl Ritter von Frisch (1886-1982) did fundamental investigations on fish and honey-bees. He studied the orientation of bees following colors, shapes, odors, the sun and polarized light. He received the 1973 Nobel prize for medicine.
