19126 Ottohahn           Discovered 1987 Aug. 22 by F. Borngen at Tautenburg.
Otto Hahn (1879-1968), chemistry Nobel Laureate in 1944, participated in the discovery of numerous radioactive elements and isotopes, as well as of the nuclear fission of uranium by neutron bombardment in 1938. As president of the Max-Planck-Gesellschaft during 1948-1960 he warned of the dangers of atomic energy.
