Otto Hahn in an obituary: Hahn's death did not stop his public acclamation. Proposals were made at different times, first in 1971 by American chemists, that the newly synthesized element no. 105 should be named hahnium in Hahn's honor; in 1997 the IUPAC (International Union of Pure and Applied Chemistry) named it dubnium, after the Russian research center in Dubna (see element naming controversy). Although element 108 was given the name hassium (after Hesse) by its officially recognized German discoverers in 1992, a 1994 IUPAC committee recommended that it be named hahnium (Hn), in spite of the long-standing convention to give the
Otto Hahn as the name for one of Hahn's newly discovered elements - meaning "parallel to radium" - Hahn rejected the suggestion on the grounds that the name was too reminiscent of military activity and goose-stepping. In 1914, for the discovery of mesothorium I (radium-228), Otto Hahn was first nominated for the Nobel Prize in Chemistry by Adolf von Baeyer and, in June 1907, by means of the traditional "habilitation" thesis, Hahn qualified to teach at the University of Berlin. On 28 September 1907 he made the acquaintance of the Austrian physicist Lise Meitner who was almost the same age, who had
