Elias James Corey
Elias James ""E.J."" Corey (born July 12, 1928) is an American organic chemist. In 1990, he won the Nobel Prize in Chemistry ""for his development of the theory and methodology of organic synthesis"", specifically retrosynthetic analysis. Regarded by many as one of the greatest living chemists, he has developed numerous synthetic reagents, methodologies and total syntheses and has advanced the science of organic synthesis considerably.
