Up for sale the "Nobel Prize in Chemistry" Jean-Marie Lehn Hand Signed 4X6 Card.  

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 created by intermolecular interactions, and continues to innovate in

this field. As of January 2006, his group has published 790

peer-reviewed articles in chemistry literature. Lehn

was born in Rosheim, Alsace, France to Pierre and Marie Lehn. He is of Alsatian German

descent. His father was a baker, but because of his interest in music, he later

became the city organist. Lehn also studied music, saying that it became his

major interest after science. He has continued to play the organ throughout his

professional career as a scientist. His high school studies in Obernai, from 1950 to 1957, included Latin, Greek, German, and

English languages, French literature, and he later became very keen of both

philosophy and science, particularly chemistry. In July 1957, he obtained the baccalauréat in philosophy, and in September of the same year, the

baccalauréat in Natural Sciences. At the

University of Strasbourg, although he considered

studying philosophy, he ended up taking courses in physical, chemical and

natural sciences, attending the lectures of Guy Ourisson, and realizing that he wanted to pursue a

research career in organic chemistry. He joined Ourisson's lab, working his way

to the Ph.D. There, he was in charge of the lab's first NMR spectrometer, and

published his first scientific paper, which pointed out an additivity rule for substituent

induced shifts of proton NMR signals in steroid derivatives. He obtained his

Ph.D., and went to work for a year at Robert Burns Woodward's

laboratory at Harvard University,

working among other things on the synthesis of vitamin B12. In 1966, he was appointed a position as maître

de conférences (assistant professor) at the Chemistry Department of

the University of Strasbourg.

His research focused on the physical properties of molecules, synthesizing

compounds specifically designed for exhibiting a given property, in order to

better understand how that property was related to structure. In 1968, he

achieved the synthesis of cage-like molecules, comprising a cavity inside which

another molecule could be lodged. Organic chemistry enabled him to engineer

cages with the desired shape, thus only allowing a certain type of molecule to

lodge itself in the cage. This was the premise for an entire new field in

chemistry, sensors. Such mechanisms also play a great role in molecular biology. These cryptands, as Lehn dubbed them,

became his main center of interest, and led to his definition of a new type of

chemistry, "supramolecular chemistry", which instead of studying the

bonds inside one molecule, looks at intermolecular attractions, and what would

be later called "fragile objects", such as micelles, polymers, or

clays. In 1980, he was elected to become a teacher at the prestigious Collège de France, and in

1987 was awarded the Nobel Prize, alongside Donald Cram and Charles Pedersen

for his works on cryptands. He is currently a member of the Reliance Innovation

Council which was formed by Reliance Industries

Limited, India. Lehn was married in 1965 to Sylvie Lederer, and

together they had two sons, David and Mathias.
