Professor Jean-Marie Lehn (born September 30, 1939, in Rosheim, France) is a French Chemist who earned a Ph.D. in Chemistry from the University of Strasbourg in 1963. He is a Professor at the University of Strasbourg, Institute for Advanced Study (USIAS), Emeritus Professor at the University of Strasbourg, and Honorary Professor at the Collège de France in Paris.

He shared the Nobel Prize in Chemistry in 1987 for his studies on the chemical basis of "Molecular Recognition" (i.e., the way in which a receptor molecule recognizes and selectively binds a substrate), which plays a fundamental role in biological processes. Over the years, his work led to the definition of a new field of chemistry, which he has proposed calling "Supramolecular Chemistry.” It deals with the complex entities formed by the association of two or more chemical species held together by intermolecular forces. Subsequently, the area developed into the chemistry of "Self-Organization" processes and, more recently into "Constitutional Dynamic Chemistry.”

Professor Lehn founded the Institute of Supramolecular Science and Engineering (ISIS) in Strasbourg in 2002. He has been involved in a large number of public and private boards and committees and also participated in several start-up companies. As president of the non-governmental International Organization for Chemical Sciences in Development (IOCD), he aims, together with a group of dedicated colleagues, to contribute to helping chemists in developing countries.

Author of more than 1000 scientific publications and two books, Lehn is a member of many academies and institutions. He has received numerous international honors and awards, among them Officer of the French National Order of Merit (1993), Grand Officer of the French Legion of Honour (2014), Österreichisches Ehrenzeichen für Wissenschaft und Kunst, (Austrian Decoration for Science and Art -first class, 2001), the Grosses Verdienstkreuz mit Stern der Bundesrepublik Deutschland (Knight Commander's Cross of the Order of Merit of the Federal Republic of Germany - 2009), and was conferred the Order of the Rising Sun, Second Class, Gold, and Silver Star by the Government of Japan (2019).

Prof. Atta-ur-Rahman (FRS) is a Fellow of the Royal Society (London), and an Honorary Life Fellow of the Kings College Cambridge University. He is the author/editor of 300 books published by major US/European presses and has 1,200 research publications, 62 chapters in books and 15 patents to his credit. He is the Editor-in-Chief of several Chemistry journals, including Current Medicinal Chemistry. He is also the editor of a novel book series Studies in Natural Product Chemistry, being published by Elsevier Science Publishers. 87 Volumes of this monumental book series have already been published.

Prof. Atta-ur-Rahman has been awarded Doctor of Science degrees by several universities, including Cambridge University and the UNESCO Science Prize (1999) as well as the highest civil awards of the Government of Pakistan, Austria and China for his contributions to medicinal chemistry and education. Several institutions have been established in different countries, such as Malaysia, China and Pakistan.
