“for his discovery, by means of his mass spectrograph, of isotopes, in a large number of non-radioactive elements, and for his enunciation of the whole-number rule”
Francis William Aston was a British chemist and physicist who worked at the University of Cambridge. He developed the mass spectrograph and used it to discover isotopes in many non-radioactive elements, also formulating the whole-number rule. He was awarded the Nobel Prize in Chemistry in 1922 for these discoveries.
