Joseph Proust formulated his theory, known as the Law of Definite Proportions, in the early 19th century, with significant contributions published in 1799. This theory states that a chemical compound always contains its component elements in fixed ratio by mass, regardless of the amount of the compound. Proust's work laid foundational principles for modern chemistry and the understanding of chemical composition.
