Albert Györgyi Early Life Video

R.I.P. Albert Györgyi

By the midth century scurvy had debilitated hundreds of thousands of British sailors and others whose diet was heavily dependent on meat and starch and devoid of fresh vegetables and citrus fruits.

The first step in eradicating this disease came in , when James Lind, a Scottish physician, wrote an essay recommending mandatory consumption of citrus fruits and lemon juice by sailors in the British Navy.

During his years as a British naval surgeon, Lind had observed the curative and preventive powers of citrus fruits in sailors suffering from scurvy.

But it would be more than a century before scientists would understand exactly why citrus fruits were so effective in combating the deadly disease.

In Axel Holst and Alfred Fröhlich, two Norwegians, posited the existence of vitamin C on the basis of its biological effects, and an international competition ensued to isolate the vitamin.

In Albert Szent-Györgyi — isolated a substance that was identified four years later as vitamin C. The subsequent work of Szent-Györgyi and other investigators finally explained the link between vitamin C and the treatment and prevention of scurvy.

While conducting a series of experiments on citrus plants, he found that browning could be induced with peroxidase, a plant enzyme active in oxidation.

Szent-Györgyi was then able to delay the browning with the addition of citrus juice to the peroxidase. Further experiments allowed Szent-Györgyi to isolate the protective hexuronic-acid agent he believed was active in citrus juice.

Life is a wondrous phenomenon. In , Szent-Györgyi returned to Hungary, accepting a post as professor of medicinal chemistry at the University of Szeged.

There he showed his sample of hexuronic acid to J. Svirbely, an American-born chemist of Hungarian descent, who had previously worked with Charles King, a vitamin researcher at the University of Pittsburgh.

Svirbely, working with Szent-Györgyi, conducted a landmark experiment on guinea pigs, which, like humans, must ingest vitamin C to maintain health since it cannot be produced within their bodies.

Svirbely divided the animals into two groups: one that received boiled food boiling destroys vitamin C and the other that was fed food enriched with hexuronic acid.

The latter group flourished, while the first aggregation of guinea pigs developed scurvy-like symptoms and died. Svirbely and Szent-Györgyi decided hexuronic acid — renamed ascorbic acid to reflect its anti-scurvy properties — was indeed the long sought vitamin C.

In , Szent-Györgyi set about to find additional, natural sources of ascorbic acid for further study. Although orange juice and lemon juice have high levels of ascorbic acid, they contain sugars that make purification extremely difficult.

Szent-Györgyi solved the problem by making imaginative use of the local specialty, paprika. Szeged is the paprika capital of the world, where matching salt and paprika shakers are found on every restaurant table.

One night, Szent-Györgyi recalled, his wife served him fresh red paprika for supper. Suddenly it occurred to me that this is the one plant I had never tested.

I took it to the laboratory Within several weeks Szent-Györgyi had produced three pounds of pure crystalline ascorbic acid, enough to show — when fed to the vitamin C-deficient guinea pigs — that the acid was equivalent to vitamin C.

Just four years after the ascorbic acid discovery, Szent-Györgyi received the Nobel Prize for his seminal work.

That year, in , the deliberations in the Nobel Committee centered on whether the Prize should go to Szent-Györgyi alone or be shared with several other scientists who had conducted similar work.

In the end, the Prize was given to Szent-Györgyi alone, but the deliberations were reportedly long and acrimonious. Szent-Györgyi went on to identify and study actin and myosin, proteins responsible for muscle contraction, and demonstrated that the compound adenosine triphosphate ATP is the immediate source of energy necessary for muscle contraction.

He later carried out additional studies of citrus fruits, identifying flavonoids and postulating its function as strengthening capillary blood vessels.

After the war, Szent-Györgyi began his research career in Pozsony today Bratislava , Slovakia. 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 the University of Cambridge. He received his PhD from the University of Cambridge in [15] where he was a student at Fitzwilliam College, Cambridge.

His research involved isolating an organic acid , which he then called "hexuronic acid", from adrenal gland tissue.

He accepted a position at the University of Szeged in After Walter Norman Haworth had determined the structure of vitamin C, and in honour of its antiscorbutic properties, it was given the formal chemical name of L-ascorbic acid.

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 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 ".

Albert Szent-Györgyi offered all of his Nobel prize money to Finland in The Hungarian Volunteers in the Winter War travelled to fight for the Finns after the Soviet invasion of Finland in In 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.

In , Albert received the Cameron Prize for Therapeutics of the University of Edinburgh. In 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 , 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 , grants from the Armour Meat Company and the American Heart Association allowed him to establish the Institute for Muscle Research.

During the s Szent-Györgyi began using electron microscopes to study muscles at the subunit level. He received the Lasker Award in In , he became a naturalized citizen of the United States.

He was elected a Member of the National Academy of Sciences NAS in In the late s, Szent-Györgyi developed a research interest in cancer and developed ideas on applying the theories of quantum mechanics to the biochemistry quantum biology 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 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 , reflecting his interests in quantum physics, he proposed the term " syntropy " replace the term " negentropy ". Right from the beginning, however, Szent-Györgyi felt the medical profession had misled the public about the implications of his findings.

Attesting to the remarkable safety of vitamin C, he insisted that one can take any amount of it without the least danger.

Albert Szent-Györgyi was born in Budapest, Hungary, in Raised in a family that had three generations of scientists, he became interested in science at an early age.

Szent-Györgyi began studying medicine at the Semmelweis University medical school in Budapest in , but his studies were interrupted by the outbreak of World War I.

Sent to serve as an army medic, he soon became disillusioned with the conflict. A fervent proponent of disarmament and peace, Szent-Györgyi eventually shot himself in the arm deliberately, claimed to have been hit by enemy fire, and managed to get home to finish his medical degree.

After graduating from Budapest in , he went on to do further study and research at various universities across Europe. He also spent a year at the Mayo Clinic in the United States.

Albert Szent-Gyorgyi receiving the Nobel Prize in Physiology or Medicine in Stockholm, Sweden. While studying oxidation reactions that cause a brown pigmentation to appear in certain fruits as they decay, Szent-Györgyi discovered that cabbages contain a reducing agent a substance that donates electrons in a chemical reaction that prevents these reactions from occurring.

He also found that the adrenal glands of animals contained this agent. This led to a reproduction of the fundamental reaction of muscle contraction which formed the foundation of muscle research in the following decades.

The preservation of biological material in glycerine, which has had extensive application including agricultural use in the preservation of sperm, has resulted from his more recent work.

He has also developed the use of rabbit psoas muscle as an experimental material, published theories on the problems of energetics and investigated the regulation of growth and cell membrane potential, and the hormonal function of the thymus gland.

Szent-Györgyi, a member of many scientific societies, is a Past President of the Academy of Sciences, Budapest, and a Vice-President of the National Academy, Budapest.

He received the Cameron Prize Edinburgh in and the Lasker Award in His many publications include Oxidation, Fermentation, Vitamins, Health and Disease ; Muscular Contraction ; The Nature of Life ; Contraction in Body and Heart Muscle ; and Bioenergetics In , he married Marta Borbiro, a co-worker at Woods Hole.

From until his death, he worked in the United States where he was also involved in cancer research. After the war, Szent-Györgyi began his research career in Pozsony today BratislavaSlovakia. Szent-Györgyi received a medical degree upon graduation, thereafter studying at various European Albert Györgyi. He began his scientific career by studying the chemical changes that occur when cells utilize foodstuffs, such as carbohydrates, fats, and protein, a process sometimes known as biological combustion.

This celebration here tells me that Wolfgang Pauritsch Familie work is not hopeless. Scurvy was among many diseases suffered due to malnutrition. Four years later, as a professor at the University of Szeged, Hungary —45he helped prove that the acid is identical to the antiscurvy vitamin C, which had been discovered in by Axel Holst and Alfred Fröhlich.
