Joseph Louis Proust (26 September 1754 – 5 July 1826) was a French chemist. He was best known for his discovery of the law of definite proportions in 1794, stating that chemical compounds always combine in constant proportions.
Joseph-Louis Proust was a French chemist who proved that the relative quantities of any given pure chemical compound’s constituent elements remain invariant, regardless of the compound’s source. This is known as Proust’s law, or the law of definite proportions (1793), and it is the fundamental.

Joseph Louis Proust. 1754-1826. French chemist famous for discovering the law of constant proportions, or Proust's law, according to which pure samples of a compound always contain the same elements in definite proportions.
In chemistry, the law of definite proportions, sometimes called Proust's law or the law of constant composition, states that a given chemical compound always contains its component elements in fixed ratio (by mass) and does not depend on its source and method of preparation.
Joseph Louis Proust, b. Sept. 26, 1754, d. July 5, 1826, was a French chemist whose careful research on many chemical substances demonstrated convincingly that each pure compound has a characteristic elemental composition.
Joseph Louis Proust. Compounds (Joseph Louis Proust) Between 1798 and 1808, Joseph Louis Proust analyzed different sources of several compounds. He found that they always contained the same ratio by weight of their elements.
