The name that was proposed by the team of scientists at the University of California, Berkeley, in honour of the German physicist Otto Hahn, for element 105 in the periodic table, which they had discovered. A team at the Joint Institute for Nuclear Research in the then USSR had also discovered the element independently and proposed their own name. The dispute was finally resolved by calling the element dubnium, after the town of Dubna, where the Soviet institute was located. The name was finally agreed and published in 1997.
