Joseph-Louis Proust, (born Sept. 26, 1754, Angers, France—died July 5, 1826, Angers), 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. 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. [1] Life Joseph L. Proust was born on September 26, 1754, in Angers, France. His father served as an apothecary in Angers.

Angers, 5 July 1826) chemistry. The second son of Joseph Proust, an apothecary, and Rosalie Sartre, Proust received his early education under the supervision of his godparents and continued it at the local Oratorian collège. He was then apprenticed to his father, to study pharmacy and to succeed him. The Law of Constant Composition, discovered by Joseph Proust, is also known as the Law of Definite Proportions. It is different from the Law of Multiple Proportions although both stem from Lavoisier's Law of Conservation of Mass. The French chemist Joseph Proust stated this law the following way: "A chemical compound always contains the same. Joseph Louis Proust, a French chemist working in Spain, was born Sep. 26, 1754. In 1794, Proust published a paper, "Researches on Prussian blue," in which he first set down the law of definite proportions, or Proust's law, as it is commonly known.

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. A Young Chemist Joseph L. Proust was born on September 26, 1754 in Angers, France as the second son of Joseph Proust, an apothecary, and Rosalie Sartre. Joseph studied chemistry in his father's shop and later came to Paris, where he studied chemistry with Hilaire-Martin Rouelle. law of definite proportions, statement that every chemical compound contains fixed and constant proportions (by mass) of its constituent elements.Although many experimenters 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. The law of definite proportion was given by Joseph Proust in the Spanish city of Segovia in 1797. [2] This observation was first made by the English theologian and chemist Joseph Priestley, and Antoine Lavoisier, a French nobleman and chemist centered on the process of combustion. This is how Proust phrased the law in 1794. [3]

Joseph Proust (1754-1826) formulated the law of definite proportions (also called the Law of Constant Composition or Proust's Law), which states that if a compound is broken down into its constituent elements, the masses of the constituents will always have the same proportions, regardless of the quantity or source of the original substance. A few years previously, the French chemist Joseph Proust had proposed the law of definite proportions, which expressed that the elements combined to form compounds in certain well-defined proportions, rather than mixing in just any proportion; and Antoine Lavoisier proved the law of conservation of mass, which also assisted Dalton.
