19136 Strassmann           Discovered 1989 Jan. 10 by F. Borngen at Tautenburg.
Friedrich Wilhelm Strassmann (1902-1980), a collaborator at the Kaiser-Wilhelm-Institut in Berlin and professor at the University of Mainz since 1946, worked on artificial radio-nucleides and methods for geological age determinations. With Otto Hahn and Lise Meitner, he received the Enrico Fermi prize in 1966.
