This substance was accidentally discovered about two years ago by M. Courtois, a manufacturer of saltpetre at Paris. In his processes for procuring soda from the ashes of sea weeds, (cendres de vareck) he found the metallic vessels much corroded; and in searching for the cause of this effect, he made the discovery.

[38] Oxygen, discovered by Carl Wilhelm Scheele in Uppsala, Sweden, in 1772, and labelled "fire air", would be renamed by Antoine Lavoisier in 1778. [39] Hydrogen by Antoine Lavoisier in 1783.

Registered Pharmacist (1808), lecturer in chemistry at the École Polytechnique (1811), Deputy Professor in History of pharmaceutical matters (1811) then Professor (1814) then Administrator-Treasurer (1824) at the Ecole de Pharmacie now the Faculté de Pharmacie see [3], member then Secretary General (1817) and President (1826) of the Société de Pharmacie later on known as Académie ...
The most celebrated discoveries of Scottish chemist William Ramsay were made in inorganic chemistry. Ramsay was intrigued by the British physicist John Strutt, 3rd Baron Rayleigh's 1892 discovery that the atomic weight of nitrogen found in chemical compounds was lower than that of nitrogen found in the atmosphere. He ascribed this discrepancy ...
Its discovery is generally believed to have originated in India around the 4th century AD, [65] although Singaporean mathematician Lam Lay Yong claims that the method is found in the Chinese text The Nine Chapters on the Mathematical Art, from the 1st century AD. [66] 60 AD: Heron's formula is discovered by Hero of Alexandria. [67]
Francium was discovered by Marguerite Perey [4] in France (from which the element takes its name) on January 7, 1939. [5] Before its discovery, francium was referred to as eka-caesium or ekacaesium because of its conjectured existence below caesium in the periodic table. It was the last element first discovered in nature, rather than by synthesis.
An image from John Dalton's A New System of Chemical Philosophy, the first modern explanation of atomic theory.. This timeline of chemistry lists important works, discoveries, ideas, inventions, and experiments that significantly changed humanity's understanding of the modern science known as chemistry, defined as the scientific study of the composition of matter and of its interactions.
Joseph-Louis Proust was born on 26 September 1754 in Angers, France. His father served as an apothecary in Angers. Joseph studied chemistry in his father's shop and later went to Paris where he gained the appointment of apothecary in chief to the Salpêtrière. [2] He also taught chemistry with Pilâtre de Rozier, a famous aeronaut. [2]
