Sir Geoffrey Wilkinson was an English
chemist.
He was born 14 July 1921 in the village of Springside, near Todmorden in
Yorkshire. His father, also a Geoffrey, was a master house painters and
decorator; his mother worked in a local cotton mill. One of his uncles, an
organist and choirmaster, had married into a family that owned a small chemical
company making Epsom and Glauber's salt for the pharmaceutical industry. This is
where he first developed an interest in Chemistry.
He was educated in the local council primary school and, after winning a County
Scholarship in 1932, went to Todmorden Secondary School. There, he had the same
Physics teacher as Sir John Cockcroft, who received a Nobel Prize for “splitting
the atom”.
In 1939 he obtained a Royal Scholarship for study at the Imperial College London
where he graduated in 1941. In 1942, Professor Friedriech A. Paneth was
recruiting young chemists for the nuclear energy project. He joined, and was
sent out to Canada and remained in Montreal and later Chalk River until he could
leave in 1946. For the next four years he worked with Professor Glenn T. Seaborg
at Berkeley, California, mostly on nuclear taxonomy. He then became a Research
Associate at the Massachusetts Institute of Technology and began to return to
his first interest as a student - transition metal complexes such as carbonyls
and olefin complexes.
He was then at Harvard from September 1951 until he returned to England in
December, 1955, with a sabbatical break of nine months in Copenhagen. At
Harvard, he still did some nuclear work on excitation functions for protons on
cobalt but had already begun to work on olefin complexes.
In June 1955, he was appointed to the chair of Inorganic Chemistry at Imperial
College in the University of London, and from then on worked, almost entirely on
the complexes of transition metals.
He is well known for his invention of the Wilkinson Catalyst RhCl(PPh3)3 and for
the discovery of the structure of ferrocene. The Wilkinson catalyst is used
industrially in the hydrogenation of alkenes to alkanes.
He received many awards, including the Nobel Prize for Chemistry in 1973 for his
work on “organometallic compounds” (with Ernst Otto Fischer).
He was married, with two daughters. Sir Geoffrey Wilkinson died on 26 September
1996.
