Francis William Aston
Chemist
A British chemist who won the 1922 Nobel Prize in Chemistry for discovering isotopes in a large number of non-radioactive elements. He was also the first to fully formulate the whole number rule, which posits that the masses of isotopes are whole number multiples of the mass of a given hydrogen atom.
He worked on fermentation chemistry at the school of brewing in Birmingham, and was later employed by W. Butler & Co. Brewery.
The lunar crater Aston was named in his honour.
He had two siblings.
He played golf with his colleague Ernest Rutherford.
