Selenium was discovered in 1817 by Jons Jakob Berzelius and Johan Gottlieb Gahn. Selenium is an ingredient in many multivitamins and other dietary supplements. Se compounds confer a red color to glass. Small amounts of organoselenium compounds are used to modify the vulcanization catalysts used in the production of rubber.
