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.

He made his findings public on July 21, 1820, in an article entitled Mémoire sur la découverte d'un nouveau remède contre le goître in Geneva.

[1] After his findings became public, many other physicians also began to prescribe iodine which led to a high rate of adverse effects.

Coindet advised to control the dose of iodine closely to limit adverse effects.

[1] In 1831, Coindet was awarded a major prize by the French Academy of Sciences for his research about iodine.
