Courtois was acknowledged by Humphry Davy and Joseph Louis Gay-Lussac as the true discoverer of iodine. In 1822, he began manufacturing high-quality iodine and its salts. In 1831, he was awarded 6,000 francs as part of the Montyon Prize by L'Academie royale des sciences, for the medicinal value of the element. He struggled financially for the ...
Courtois discovered it in the ashes of seaweed. [117] The name iode was given in French by Gay-Lussac and published in 1813. [52] Davy gave it the English name iodine in 1814. [52] 3 Lithium: 1817 A.

The element iodine was discovered by French chemist Bernard Courtois in 1811. [76] [77] Courtois gave samples to his friends, Charles Bernard Desormes (1777–1862) and Nicolas Clément (1779–1841), to continue research. He also gave some of the substance to Gay-Lussac and to physicist André-Marie Ampère. On December 6, 1813, Gay-Lussac ...
In 1811, Bernard Courtois discovered iodine was present in seaweed, and iodine intake was linked with goitre size in 1820 by Jean-Francois Coindet. [80] Gaspard Adolphe Chatin proposed in 1852 that endemic goitre was the result of not enough iodine intake, and Eugen Baumann demonstrated iodine in thyroid tissue in 1896. [80]
Jean-François Coindet (July 12, 1774 – February 11, 1834) was a Swiss physician and researcher who is known for introducing iodine as a treatment of goitre. [1]Jean-François Coindet was born on July 12, 1774, in Geneva as the son of Jean Jacques Coindet and Catherine Gros.
French chemist Bernard Courtois discovered iodine in 1811, [92] and in 1896 Eugen Baumann documented it as the central ingredient in the thyroid gland. He did this by boiling the thyroid glands of a thousand sheep, and named the precipitate, a combination of the thyroid hormones, 'iodothyrin'. [ 92 ]
