Discovery of hafnium announced

In 1922, the discovery of hafnium by Dirk Coster and Georg von Hevesy was announced by Neils Bohr as he concluded his Nobel Prize lecture, 'On The Structure of Atoms.'. Bohr received the news by telephone from Coster, just a few minutes before he began his lecture, that the β1 and β2 lines of hafnium had been identified on a photographic plate.

The discovery of hafnuium was shortly afterwards published in the 20 Jan 1923 issue of the journal Nature.
