Joseph Proust (1754-1826) proposed the the Law of Constant Composition in 1799. This law was very radical at the time and was hotly contested by Claude Berthollet (1748-1822). John Dalton (1776-1844) proposed the Law of Multiple Proportions. This law led directly to the proposal of the Atomic Theory in 1803. He also developed the concept of the mole and proposed a system of symbols to represent atoms of different elements. (The symbols currently used were developed by J.J. Berzelius(1779-1848)).
