Proust
The law of definite composition was developed by French chemist Joseph Proust in the late 18th century. He formulated this law based on his experiments with chemical compounds, which stated that a given compound always contains the same elements in fixed proportions by mass.
Oxygen was discovered for the first time by a Swedish Chemist, Carl Wilhelm Scheele, in 1772. Joseph Priestly, an English chemist, independently, discovered oxygen in 1774 and published his findings the same year, three years before Scheele published. Antoine Lavoisier, a French chemist, also discovered oxygen in 1775, was the first to recognize it as an element, and coined its name "oxygen" - which comes from a Greek word that means "acid-former". Where is was found? I do not know.

Mohr salt is named after the German chemist Karl Friedrich Mohr, who first synthesized it in 1855. He discovered the compound's chemical composition and properties that are frequently used in analytical chemistry and titration methods.

The English chemist and physicist Henry Cavendish, b. Oct. 10, 1731, d. Feb. 24, 1810, was the first to recognize hydrogen gas as a distinct substance. He also described the composition of water and made the first accurate measurement of the density of the Earth.
