For a number of years professor Niels Bohr at the University of Copenhagen was the central figure in the international work on the development of nuclear physics and his modest Institute for Theoretical Physics became the most important meeting place and place of learning for the world's young nuclear physicists. It has left permanent marks in the scientif-ic nomenclature. For instance, the element which has number 72 and which was long unknown was called Hafnium because it was discovered at Niels Bohr's institute and named after the Latin form of Copenhagen, Hafnia.
