Bernard Courtois

Born 8 Feb 1777; died 27 Sep 1838 at age 61. French chemist who discovered the element iodine. As the son of a saltpeter manufacturer from Dijon, he grew interested in chemistry and was apprenticed to a pharmacist. While in military service as a pharmacist, he became the first to isolate pure morphine from opium (1804). He returned to assist at his father's saltpeter business, where the ashes of kelp seaweed were leached for sodium and potassium salts using sulphuric acid. In 1811, from the mother liquor, he observed rising clouds of purple vapour which condensed on cold surfaces as dark crystals with a metallic lustre. He thought these could be a new element, but lacked ability to fully confirm his suspicion. This was later verified by Joseph-Louis Gay-Lussac and Humphry Davy.«
