Solution
John Dalton (1766-1844) was an English meteorologist. He proposed the Atomic Theory in 1803.
Dalton's theory was presented in New System of Chemical Philosophy (1808-1827). He proposed a new set of standard symbols for the chemical elements in the first volume of his New System. So the exact year can not be given. It may be some where in between 1808 to 1827
