In a series of pioneering experiments in 1913/1914, the British physicist Henry Moseley showed that the frequencies of X-rays emitted from different elements under electron bombardment is linked to the order number of the element in the periodic table, proposing this number as the charge of the atomic nucleus. Moseley, nominated for Nobel prizes in both Chemistry and Physics, was killed in action during the Great War in August 1915. The statutes of the Nobel Foundation do not allow for posthumous awards. However, the enormous importance of Moseley's work was widely recognized at the time and in 1919 he did win another major international prize in physics, namely the Matteucci Medal, awarded by the Italian Society of the Sciences, the Academy of the Forty.
