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 their discovery Hahn and Meitner were repeatedly nominated for the Nobel Prize in Chemistry in the 1920s by a number of scientists, among them Max Bergmann, Viktor Moritz Goldschmidt, and even Fajans himself. In 1949, the International Union of Pure and Applied Chemistry (IUPAC) named the new element definitely protactinium, and confirmed Hahn and Meitner as discoverers. In February 1921, Otto Hahn published the first report on his discovery of uranium Z (later known as Pa ), the first example of nuclear isomerism. Gerlach remarked that this was "a discovery that was not understood at the time but later became
