Ian Fleming (born 1935) is an English organic chemist, and an emeritus professor of the University of Cambridge, and an emeritus fellow of Pembroke College, Cambridge. He was the first to determine the full structure of chlorophyll (in 1967)[1] and was involved in the development of the synthesis of cyanocobalamin by Robert Burns Woodward. He has made major contributions to the use of organosilicon compounds for stereospecific syntheses; reactions which have found application in the synthesis of natural compounds. He is also a prolific author, and has written a number of textbooks, encyclopedia chapters and influential review articles.[citation needed]
