He
was born on June 12th, 1899, at Koenigsberg, Germany. He was the son
of Leopold Lipmann and his wife Gertrud Lachmanski.
Lipmann was educated, during the years 1917-1922, at the Universities
of Koenigsberg, Berlin, and Munich, where he studied medicine. He took
his M.D. degree in 1924 at Berlin. He was, during his pre-clinical year
of medical study, strongly impressed by what he has called Ğa dramatic
chemistry courseğ given by Professor Klinger at Koenigsberg. Later,
he took a primer course in biochemistry given in Berlin by Professor
Rona and in 1923 he definitely took up biochemistry, and held for a
time a Fellowship in the Department of Pharmacology, at the University
of Amsterdam, under Professor Ernst Laqueur. Feeling then the need for
further study of chemistry, Lipmann returned to Koenigsberg to study
chemistry under Professor Hans Meerwein, who had then succeeded Professor
Klinger. In 1926 he went as an assistant in Otto Meyerhof's laboratory
at the Kaiser Wilhelm Institute, Berlin, to prepare a thesis for the
degree of Ph.D., Berlin, which he took in 1927. He then went with Meyerhof
to Heidelberg, where he did further research on the biochemical reactions
occurring in muscle.
In 1930 Lipmann went back to the Kaiser Wilhelm Institute in Berlin
to work as a research assistant in the laboratory of Albert Fischer,
who was interested in applying biochemical methods to tissue culture.
Fischer was then getting ready to occupy a new Institute in Copenhagen
and he asked Lipmann to accompany him there, which he did in 1932. The
years 1931 and 1932, however, he spent as a Rockefeller Fellow in the
laboratory of P. A. Levene at the Rockefeller Institute in New York,
where he identified serine phosphate as the constituent of phosphoproteins
which contains the phosphate.
When he went to Copenhagen in 1932, as Research Associate in the Biological
Institute of the Carlsberg Foundation there, Lipmann became interested
in the metabolism of fibroblasts and this prompted him to investigate
the Pasteur effect, which led to important papers on the mechanism of
this reaction and on the part played by glycolysis in the metabolism
of the cells of embryos.
In 1939 Lipmann became Research Associate in the Department of Biochemistry,
Cornell Medical School, New York, and in 1941 joined the research staff
of the Massachusetts General Hospital in Boston, first as a Research
Associate in the Department of Surgery, then heading his own group in
the Biochemical Research Laboratory of the Hospital. In 1949 he became
Professor of Biological Chemistry at Harvard Medical School, Boston.
In 1957, he was appointed a Member and Professor of the Rockefeller
Institute, New York, a post which he still holds.
During the late forties and early fifties, the wealth of problems opened
up by the discovery of coenzyme A attracted much attention. He left
this post to explore the chemical nature of some seemingly unusual phosphate
derivatives arising in the process of group activation through phosphoryl
transfer from ATP. Thus, through observations on a phosphorolysis of
citrulline, his attention was drawn to the probability of carbamyl phosphate
(CMP) representing the metabolically active carbamyl donor. The suspicion
proved justified, and proof of metabolic formation and its function,
in collaboration with Mary Ellen Jones and Leonard Spector, was greatly
simplified by the latter's discovery of an unexpectedly simple method
of chemical CMP synthesis through condensation of cyanate and phosphate
at room temperature and in excellent yield.
Another unusual phosphate derivative had been indicated through the
function of ATP in sulphate activation. Work with Hilz and Robbins in
this area brought out the existence of a new class of chemical compounds,
the mixed anhydrides between phosphate and sulphate; adenosine-5'-phosphosulphate
(APS) and 3'-phosphoadenosine-5'-phosphosulphate (PAPS) were identified
as Ğactiveğ sulphates. The latter compound, PAPS, was found in animals
and plants to be the common sulphate donor in the sulphurylation of
mono- or poly-saccharides and other sulphate derivatives.
Recently, most of his attention has returned to development of the biological
mechanism of peptide and protein synthesis. At present, this is what
has become his major interest.
Lipmann is a member of several learned societies in the U.S.A., the
Faraday Society, and the Danish Royal Academy of Sciences and is a Foreign
Member of the Royal Society of England. He holds honorary degrees of
the Universities of Marseilles, Chicago and Chile, and is Doctor of Humane Letters of Brandeis
University. In 1931, he married Elfreda M. Hall, and they have one son,
Steven.
From
Nobel Lectures, Physiology or Medicine 1942-1962.
Dr
Lipmann died in 1986.
