Georg
Wittig – Born in Berlin in
1897. Doctorate and University Teaching Thesis in Marburg/Lahn
from the Faculty of Chemistry. Head of Department at Braunschweig
(Technical College) from 1932; Associate Professor at Freiburg/Brsg.
from 1937; Professor and Faculty Director at the Institute of
Chemistry, Tübingen, from 1944; turned down the same position as
successor to H. Staudinger at Freiburg/Brsg.; accepted the same
position at Heidelberg as successor to K. Freudenberg. Professor
Emeritus since 1967.
Scientific Activities
Textbook on stereochemistry, 1930. Papers on the subject of
ring tension and double bonds as well as valency tautomerism. Main
research into organic reactions of alkali metals and elaboration
of carbon-based chemistry. Discovery of the halogen-metal exchange
reaction (simultaneously with H. Gilman). Development of ylide
chemistry and, together with that, study of the Stevens and
Sommelet rearrangements as well as intra-anionic ether
isomerisation. Through the synthesis of the pentaaryl derivatives
of the elements of group 5, the phosphorous ylides were discovered
and also, in 1953, the carbonylolefins which have since proven to
be crucial for the manufacture of synthetic fabrics and also
important in other industrial processes. In 1942 dehydrobenzol was
proven to be a shortlived by-product, a fact demonstrated bye. D.
Roberts in 1953 and by me, only this time using different means,
viz. control experiments on
Diels - Alder adducts. More recently the concept of the
"at"-complexes as a counterpart to the "onium" complexes has led
to the development of a new chemistry from which have come the
sodium tetra phenylborates.
Honours
Honorary Doctorate from the Sorbonne in 1957; Honorary
Doctorate from the Universities of Tübingen and Hamburg in 1962;
Adolf von Baeyer Memorial Medal from the German Chemical Society
in 1953; Silver Medal from the University of Helsinki in 1957;

1965; Otto Hahn Award for Chemistry and Physics in 1967; Silver
Medal from the City of Paris in 1969; Paul Karrer Medal from the
University of Zurich in 1972; Médaille de la Chaire Bruylants
(University of Louvain) in 1972; Roger Adams Award from the
American Chemical Society in 1973; Karl Ziegler Prize in 1975;
Honorary Member of the Swiss Chemical Society in 1963; Honorary
Member of the New York Academy of Sciences in 1965; Member of the
Chemical Society of Peru, also in 1965; Honorary Fellow of the
Chemical Society (London) in 1967; Member of the French Academy in
1971; Member of the Society of Medical Sciences, Córdoba
(Argentina), in 1976. As well as these, member of several German
