Dubnium not have enough experimental data to back their claim. After collecting more data, JINR proposed the name "nielsbohrium" (Ns) in honor of the Danish nuclear physicist Niels Bohr, a founder of the theories of atomic structure and quantum theory. When LBL first announced their synthesis of element 105, they proposed that the new element be named "hahnium" (Ha) after the German chemist Otto Hahn, the "father of nuclear chemistry", thus creating an element naming controversy. In the early 1970s, both teams reported synthesis of the next element, element 106, but did not suggest names. JINR suggested establishing an international committee
Otto Hahn him with his Nobel Prize medal and diploma. The chemist and science historian Klaus Hoffmann wrote in his 1993 biography of Hahn (translated by J. Michael Cole, Leyburn, UK): Otto Hahn had been nominated 22 times for the Nobel Prize in Chemistry from 1914 to 1945, and 16 times for the Nobel Prize in Physics from 1937 to 1947. In 1951, Samuel C. Lind, the eminent American radiation scientist from the University of Minnesota in Minneapolis, wrote in a review: "No living man has so successfully spanned the world of discovery from radiothorium to fission, one of the greatest -
