John Dalton FRS (/ ˈ d ɔː l t ən /; 5 or 6 September 1766 – 27 July 1844) was an English chemist, physicist and meteorologist. He introduced the atomic theory into chemistry. He also researched colour blindness ; as a result, the umbrella term for red-green congenital colour blindness disorders is Daltonism in several languages.
John Dalton (born September 5 or 6, 1766, Eaglesfield, Cumberland, England—died July 27, 1844, Manchester) was an English meteorologist and chemist, a pioneer in the development of modern atomic theory.

This article will discuss John Dalton's atomic theory, which was the first complete attempt to describe all matter in terms of atoms and their properties. Basis for Dalton's theory. Dalton based his theory on two laws: the law of conservation of mass and the law of constant composition.
