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.
