## Bio

Francis William Aston was a British chemist and physicist born 1 September 1877. He built a mass spectrograph, an instrument that could measure atomic masses with unprecedented precision, and used it to discover isotopes in many non-radioactive elements — variants of the same atom with different masses. That work led him to formulate the whole number rule, a pattern governing atomic weights. The Royal Society made him a fellow, as did Trinity College, Cambridge. He died 20 November 1945.
