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 (ship) its primary purpose. It contained cabins for the group of about 36 scientists. It also contained a conference room, a meeting room and two laboratories. Its main purpose was to gain experience of future nuclear ships which could be used for transport. As the "Otto Hahn" did not receive enough permissions from harbours, the experiments ended in 1979, ten years after commissioning. Until its decommissioning, the Otto Hahn visited 33 ports in 22 countries, most of them in South America and Africa. It did not receive permission to pass through the Suez Canal and its last journey was to Durban.
