19178 Walterbothe           Discovered 1991 Sept. 9 by F. Borngen and L. D. Schmadel at Tautenburg.
A professor at Berlin, Giessen and Heidelberg, Walter Bothe (1891-1957) showed, together with W. Kohlhoerster,the particle structure of cosmic radiation. He investigated nuclear reactions and nuclear \gamma -rays and discovered artificial nuclear exitation. He shared the Nobel Prize for physics in 1954.
