Portrait by Charles Turner.

John Dalton was an Icons-flag-uk.png British chemist and physicist. He is best known for founding atomic theory, an important cornerstone of chemistry, but also for his research into color blindness, sometimes referred to as Daltonism in his honor.

John Dalton was born on 6 September, 1766. He was exceptionally bright as a child - for example, at age 12, he was placed in charge of a local school. He died on 27 July 1844 from a stroke. He lived a modest and unassuming personal life.[1]

Even though Dalton developed the atomic theory, many of the elements which he thought were made out of only one type of atom (such as lime) were actually compounds. The exact origin of his atomic theory is not yet completely understood.[2]

Various atoms and molecules as depicted in John Dalton's publication A New System of Chemical Philosophy (1808). Dalton used his own unique symbols to visually represent the atomic structure of compounds, such as salts. They were depicted in the New System of Chemical Philosophy, where he listed 20 elements and 17 simple molecules.
