Courtois

Gr. iodes, violet) Discovered by Courtois in 1811, Iodine, a halogen, occurs sparingly in the form of iodides in sea water from which it is assimilated by seaweeds, in Chilean saltpeter and nitrate-bearing earth, known as caliche in brines from old sea deposits, and in brackish waters from oil and salt wells. 

Manufacture and Processing. The industry related to iodine production began a few years after the discovery of the element by Courtois in 1811. The production processes are based on the raw materials containing iodine seaweeds, mineral deposits, and oh-weh or natural gas brines. 

B. Courtois isolated iodine by sublimation (H2SO4 4- seaweed ash)...

Bernard Courtois (1777-1838). When sulfuric add was added to the ashes obtained from seaweed, a violet gas was given off that condensed as dark crystals with a metallic luster.
