Francis William Aston.
Mass Spectra and Isotopes.
Published by Edward Arnold & Co., London, 1942

Francis William Aston (1877–1945) was a British physicist and chemist who revolutionized atomic theory by proving that most elements are mixtures of isotopes. In 1922, he was awarded the Nobel Prize in Chemistry for his discovery of isotopes in a large number of non-radioactive elements and for his formulation of the "whole-number rule"

Discovery of Stable Isotopes: He confirmed that neon consisted of two isotopes (masses 20 and 22) and went on to identify 212 of the 287 naturally occurring isotopes.
