11573 Helmholtz           Discovered 1993 Sept. 20 by F. Borngen and L. D. Schmadel at Tautenburg.
Hermann Ludwig Ferdinand von Helmholtz (1821-1894), a German doctor, physiologist and physicist, was one of the most famous naturalists of the nineteenth century. In 1847 he extended Robert Mayer's law of energy conservation to all known natural phenomena.
