Yves Chauvin (1930-2015)

French chemist born in Menin, Belgium. He worked almost all his life at the French Petroleum Institute in Rueil-Malmaison, where he developed several industrial catalytic processes.

In 1971, with Jean-Louis Hérisson, he proposed the mechanism of olefin metathesis through metal carbenes and metallacyclobutanes that now bears his name. He received the 2005 Nobel Prize in Chemistry with Robert H. Grubbs and Richard R. Schrock.
