    had long assumed the truth of the principle in general, the French chemist Joseph-Louis Proust first accumulated conclusive evidence for it in a series of researches on the composition of many substances, especially the oxides of iron (1797).  In chemistry, the law of definite proportions, sometimes called Proust's Law, states that achemical compound always contains exactly the same proportion of elements by mass. An equivalent statement is the law of constant composition, which states that all samples
