Albert Szent-Györgyi de Nagyrápolt (September
16, 1893 – October 22, 1986) was a Hungarian physiologist who won
the Nobel Prize in
Physiology or Medicine in 1937. He is credited with discovering
vitamin C and the
components and reactions of the citric acid cycle. He was also active
in the Hungarian Resistance during World War II and entered Hungarian
politics after the war.
Life in
Hungary
Szent-Györgyi was born in Budapest, Hungary. His father, Miklós Szent-Györgyi, was
a landowner. His mother, Jozefin, was a daughter of József
Lenhossék and a sister of Mihály Lenhossék; both of these men were
Professors of Anatomy at the
University of Budapest.
Szent-Györgyi began his studies at the Budapest Medical School, but soon became
bored with classes and began research in his uncle's anatomy lab.
His studies were interrupted in 1914 to serve as an army medic in
World War I. In
1916, disgusted with the war, Szent-Györgyi shot himself in the
arm, claimed to be wounded from enemy fire, and was sent home on
medical leave. He was then able to finish his medical education and
receive his MD in 1917. He married Kornélia Demény, the daughter of the
Hungarian Postmaster General that same year. She accompanied him to
his next position at an army clinic in northern Italy.
After the war, Szent-Györgyi began his research career in
Pressburg (Hungarian: Pozsony, today: Bratislava). When the city became part of Czechoslovakia in
January 1919, he left the town as did a portion of the Hungarian
population. He switched universities several times over the next
few years, finally ending up at the University of Groningen, where
his work focused on the chemistry of cellular respiration. This work
landed him a position as a Rockefeller Foundation fellow at
Cambridge University. He
received his PhD
from Cambridge in 1927 for his work on isolating what he then
called "hexuronic acid" from adrenal gland tissue.
He accepted a position at the University of Szeged in 1931.
There, Szent-Györgyi and his research fellow Joseph Svirbely found
that "hexuronic acid" was actually vitamin C (the L-enantiomer of ascorbic acid) and
noted its anti-scorbutic
activity. In some experiments they used paprika as the source for their vitamin C. Also
during this time, Szent-Györgyi continued his work on cellular
respiration, identifying fumaric acid and other steps in what would
become known as the Krebs cycle.
In 1937, he received the Nobel Prize in
Physiology or Medicine "For his discoveries in connection with
the biological combustion process with special reference to vitamin
C and the catalysis of
fumaric acid". In
1938, he began work on the biophysics of muscle movement. He found that muscles contain
actin, which when combined with
the protein myosin and the
energy source ATP, contract muscle fibers.
As fascists gained
control of politics in Hungary, Szent-Györgyi helped his Jewish friends escape from the country.
During World War
II, he joined the Hungarian resistance movement. Although
Hungary was allied with the Axis Powers, the
Hungarian prime minister Miklós Kállay sent Szent-Györgyi to Cairo
in 1944 under the guise of a scientific lecture to begin secret
negotiations with the Allies. The Germans learned of
this plot, and Adolf
Hitler himself issued a warrant for the arrest of
Szent-Györgyi. He escaped house arrest and spent 1944 to 1945 as a
fugitive from the Gestapo.
After the war, Szent-Györgyi was well-recognized as a public
figure and there was some speculation that he might become
President of Hungary, should the Soviets permit it. Szent-Györgyi
established a lab at the University of Budapest and
became head of the biochemistry department there. He was elected as
a member of Parliament and helped re-establish the Academy of
Sciences. Dissatisfied with the Communist rule of
Hungary, he emigrated to the United States in 1947.
Move
to the United States
In 1947, Szent-Györgyi established the Institute for Muscle
Research at the Marine Biological
Laboratory in Woods Hole, Massachusetts
with financial support from Hungarian businessman Stephen Rath.
However, Szent-Györgyi still faced funding difficulties for several
years, due to his foreign status and former association with the
government of a Communist nation. In 1948, he received a research
position with the National Institutes of
Health (NIH) in Bethesda, Maryland and began
dividing his time between there and Woods Hole. In 1950, grants
from the Armour Meat Company and the American Heart Association
allowed him to establish the Institute for Muscle Research.
During the 1950s, Szent-Györgyi began using electron
microscopes to study muscles at the subunit level. He received
the Lasker
Award in 1954. In 1955, he became a naturalized citizen of the United States. He
became a member of the National Academy
of Sciences in 1956.
In the late 1950s, Szent-Györgyi developed a research interest
in cancer and developed ideas
on applying the theories of quantum physics to
the biochemistry of cancer. The death of Rath, who had acted as the
financial administrator of the Institute for Muscle Research, left
Szent-Györgyi in a financial mess. Szent-Györgyi refused to submit
government grants which required him to provide minute details on
exactly how he intended to spend the research dollars and what he
expected to find. After Szent-Györgyi commented on his financial
hardships in a 1971 newspaper interview, attorney Franklin
Salisbury contacted him and later helped him establish a private
nonprofit organization, the National Foundation
for Cancer Research. Late in life, Szent-Györgyi began to
pursue free radicals as a potential cause of
cancer. He came to see cancer as being ultimately an electronic
problem at the molecular level. In 1974, reflecting his interests
in quantum physics, he proposed the term "syntropy" replace the term "negentropy". Ralph Moss,
a protegé of his in the years he performed his cancer research,
wrote a biography entitled: "Free Radical: Albert Szent-Gyorgyi and
the Battle over Vitamin C", ISBN 0-913729-78-7, (1988), Paragon
House Publishers, New York.
He died in Woods Hole, Massachusetts on
October 22, 1986.
