Although a schoolteacher, a meteorologist, and an expert on color blindness, John Dalton is best known for his pioneering theory of atomism. He also developed methods to calculate atomic weights and structures and formulated the law of partial pressures.
From his own experiments and observations, as well as the work of his peers, Dalton proposed a new theory of the atom. This later became known as Dalton's atomic theory. The general tenets of this theory are as follows: All matter is composed of extremely small particles called atoms.
