Jean-Marie Lehn

Jean-Marie Lehn (born 30 September 1939) is a French chemist. He received the Nobel Prize in Chemistry together with Donald Cram and Charles Pedersen in 1987 for his synthesis of cryptands. Lehn was an early innovator in the field of supramolecular chemistry, i.e., the chemistry of host–guest molecular assemblies created by intermolecular interactions, and continues to innovate in this field. He described the process by which molecules recognize each other. Drugs, for example, "know" which cell to destroy and which to let live. As of January 2006, his group has published 790 peer-reviewed articles in chemistry literature.
