ETYMOLOGY DICTIONARY:
- proton (n.)
- 1920, coined by English physicist Ernest Rutherford (1871-1937) from Gk. proton, neuter of protos "first" (see proto-); supposedly because hydrogen was hypothesized as a constituent of all the elements. The word was used earlier in embryology (1893) at a translation of Ger. anlage ("fundamental thing") based on Aristotle's phrase he prote ousia to proton.
