Joseph Louis Proust's 1754-1826 historical importance derives primarily from his abilities as an analyst: his development of the use of hydrogen sulfide as an analytical reagent; his use of quantitative methods-consistently giving the results of his analyses in terms pf percentage weight composition and sometimes for oxides and sulfides of the same metal the weight of oxygen or sulfur in comparsion with a constant weight of the metal without however drawing any conclusion from the results-and most significant his enunciation of the law of definitie proportions.
