Sir Frederick Gowland Hopkins OM , PRS (20 June 1861 – 16 May 1947) was an English biochemist who was awarded the Nobel Prize in Physiology or Medicine in 1929, with Christiaan Eijkman, for the discovery of vitamins, even though Casimir Funk, a Polish biochemist, is widely credited with discovering vitamins. He also discovered the amino acid tryptophan, in 1901. He was President of the Royal Society from 1930 to 1935.
Biochemists are scientists that are trained in biochemistry.
The Nobel Prize in Physiology or Medicine, administered by the Nobel Foundation, is awarded yearly for outstanding discoveries in the fields of life sciences and medicine. It is one of five Nobel Prizes established in his will in 1895 by Swedish chemist Alfred Nobel, the inventor of dynamite. Nobel was interested in experimental physiology and wanted to establish a prize for scientific progress through laboratory discoveries. The Nobel Prize is presented at an annual ceremony on 10 December, the anniversary of Nobel's death, along with a diploma and a certificate for the monetary award. The front side of the medal displays the same profile of Alfred Nobel depicted on the medals for Physics, Chemistry, and Literature. The reverse side is unique to this medal. The most recent Nobel prize was announced by Karolinska Institute on 1 October 2018, and has been awarded to American James P. Allison and Japanese Tasuku Honjo – for their discovery of cancer therapy by inhibition of negative immune regulation.
Christiaan Eijkman was a Dutch physician and professor of physiology whose demonstration that beriberi is caused by poor diet led to the discovery of antineuritic vitamins (thiamine). Together with Sir Frederick Hopkins, he received the Nobel Prize for Physiology or Medicine in 1929 for the discovery of vitamins.
Hopkins was born in Eastbourne, Sussex, and educated at the City of London School completing his further study with the University of London External Programme and the medical school at Guy's Hospital which is now part of King's College London School of Medicine.
Eastbourne is a town, seaside resort and borough in the non-metropolitan county of East Sussex on the south coast of England, 19 miles (31 km) east of Brighton. Eastbourne is immediately to the east of Beachy Head, the highest chalk sea cliff in Great Britain and part of the larger Eastbourne Downland Estate.
The City of London School, also known as CLS and City, is an independent day school for boys in the City of London, England, on the banks of the River Thames next to the Millennium Bridge, opposite Tate Modern. It is a partner school of the City of London School for Girls and the City of London Freemen's School. All three schools receive funding from the City's Cash. It is a member of the Headmasters' and Headmistresses' Conference (HMC).
Guy's Hospital is an NHS hospital in the borough of Southwark in central London. It is part of Guy's and St Thomas' NHS Foundation Trust and one of the institutions that comprise the King's Health Partners, an academic health science centre.
After graduating, Hopkins then taught physiology and toxicology at Guy's Hospital from 1894 to 1898. In 1898, while attending a meeting of the Physiological Society, he was invited by Sir Michael Foster to join the Physiological Laboratory in Cambridge to investigate the chemical aspects of physiology. Biochemistry was not, at that time, recognised as a separate branch of science. He was a lecturer in chemical physiology at Emmanuel College in March 1900, when he received the academic rank Master of Arts (MA) honoris causa.He earned a doctorate in physiology (D.Sc) from the University of London in July 1902, and at the same time was given a readership in biochemistry at Trinity College. . While at Cambridge he was initiated into Freemasonry . In 1910 he became a Fellow of Trinity College, and an Honorary Fellow of Emmanuel College. In 1914 he was elected to the Chair of Biochemistry at Cambridge University, thus becoming the first Professor in that discipline at Cambridge. His Cambridge students included neurochemistry pioneer Judah Hirsch Quastel and pioneer embryologist Joseph Needham.
Biochemistry, sometimes called biological chemistry, is the study of chemical processes within and relating to living organisms. Biochemical processes give rise to the complexity of life.
Emmanuel College is a constituent college of the University of Cambridge. The college was founded in 1584 by Sir Walter Mildmay, Chancellor of the Exchequer to Elizabeth I.
The University of London is a collegiate federal research university located in London, England. As of October 2018, the university contains 18 member institutions, central academic bodies and research institutes. The university has over 52,000 distance learning external students and 161,270 campus-based internal students, making it the largest university by number of students in the United Kingdom.
Hopkins had for a long time studied how cells obtain energy via a complex metabolic process of oxidation and reduction reactions. His study in 1907 with Sir Walter Morley Fletcher of the connection between lactic acid and muscle contraction was one of the central achievements of his work on the biochemistry of the cell. He and Fletcher showed that oxygen depletion causes an accumulation of lactic acid in the muscle. Their work paved the way for the later discovery by Archibald Hill and Otto Fritz Meyerhof that a carbohydrate metabolic cycle supplies the energy used for muscle contraction.
Archibald Vivian Hill, known as A. V. Hill, was an English physiologist, one of the founders of the diverse disciplines of biophysics and operations research. He shared the 1922 Nobel Prize in Physiology or Medicine for his elucidation of the production of heat and mechanical work in muscles.
Otto Fritz Meyerhof was a German physician and biochemist who won the Nobel Prize in Physiology and Medicine in 1922.
In 1912 Hopkins published the work for which he is best known, demonstrating in a series of animal feeding experiments that diets consisting of pure proteins, carbohydrates, fats, minerals, and water fail to support animal growth. This led him to suggest the existence in normal diets of tiny quantities of as yet unidentified substances that are essential for animal growth and survival. These hypothetical substances he called "accessory food factors", later renamed vitamins.It was this work that led his being awarded (together with Christiaan Eijkman) the 1929 Nobel Prize in Physiology for Medicine.
During World War I, Hopkins continued his work on the nutritional value of vitamins. His efforts were especially valuable in a time of food shortages and rationing. He agreed to study the nutritional value of margarine and found that it was, as suspected, inferior to butter because it lacked the vitamins A and D. As a result of his work, vitamin-enriched margarine was introduced in 1926.
World War I, also known as the First World War or the Great War, was a global war originating in Europe that lasted from 28 July 1914 to 11 November 1918. Contemporaneously described as "the war to end all wars", it led to the mobilisation of more than 70 million military personnel, including 60 million Europeans, making it one of the largest wars in history. It is also one of the deadliest conflicts in history, with an estimated nine million combatants and seven million civilian deaths as a direct result of the war, while resulting genocides and the 1918 influenza pandemic caused another 50 to 100 million deaths worldwide.
Hopkins is credited with the discovery and characterisation in 1921 of glutathione extracted from various animal tissues.At the time he proposed that the compound was a dipeptide of glutamic acid and cysteine. The structure was controversial for many years but in 1929 he concluded that it was a tripeptide of glutamic acid, cysteine and glycine. This conclusion agreed with that from the independent work of Edward Calvin Kendall.
Hopkins was elected a Foreign Associate of the National Academy of Sciences (USA) in 1924.During his life, in addition to the Nobel Prize, Hopkins was awarded the Royal Medal of the Royal Society in 1918 and the Copley Medal of the Royal Society in 1926. Other significant honours were his election in 1905 as a Fellow of the Royal Society (FRS), Great Britain's most prestigious scientific organisation; his knighthood by King George V in 1925; and the award in 1935 of the Order of Merit, Great Britain's most exclusive civilian honour. From 1930 -1935 he served as president of the Royal Society and in 1933 served as President of the British Association for the Advancement of Science.
In 1898 he married Jessie Anne Stephens (1861–1937); they had one son and two daughters, one of whom, Jacquetta Hawkes, became a prominent archeologist.
He died on 16 May 1947 in Cambridge and is buried at the Parish of the Ascension Burial Ground in Cambridge, with wife Lady Jessie Ann Hopkins.
Frederick Sanger was a British biochemist who twice won the Nobel Prize in Chemistry, one of only two people to have done so in the same category, the fourth person overall with two Nobel Prizes, and the third person overall with two Nobel Prizes in the sciences. In 1958, he was awarded a Nobel Prize in Chemistry "for his work on the structure of proteins, especially that of insulin". In 1980, Walter Gilbert and Sanger shared half of the chemistry prize "for their contributions concerning the determination of base sequences in nucleic acids". The other half was awarded to Paul Berg "for his fundamental studies of the biochemistry of nucleic acids, with particular regard to recombinant DNA".
Sir Andrew Fielding Huxley was an English physiologist and biophysicist. He was born into the prominent Huxley family. After graduating from Westminster School in Central London, from where he won a scholarship to Trinity College, Cambridge, he joined Alan Lloyd Hodgkin to study nerve impulses. Their eventual discovery of the basis for propagation of nerve impulses earned them the Nobel Prize in Physiology or Medicine in 1963. They made their discovery from the giant axon of the Atlantic squid. Soon after the outbreak of the Second World War, Huxley was recruited by the British Anti-Aircraft Command and later transferred to the Admiralty. After the war he resumed research at The University of Cambridge, where he developed interference microscopy that would be suitable for studying muscle fibres.
Sir Hans Adolf Krebs was a German-born British biologist, physician and biochemist. He was a pioneer scientist in the study of cellular respiration, a biochemical process in living cells that extracts energy from food and oxygen and makes it available to drive the processes of life. He is best known for his discoveries of two important sequences of chemical reactions that take place in the cells of humans and many other organisms, namely the citric acid cycle and the urea cycle. The former, often eponymously known as the "Krebs cycle", is the key sequence of metabolic reactions that provides energy in the cells of humans and other oxygen-respiring organisms; and its discovery earned Krebs a Nobel Prize in Physiology or Medicine in 1953. With Hans Kornberg, he also discovered the glyoxylate cycle, which is a slight variation of the citric acid cycle found in plants, bacteria, protists, and fungi. Krebs died in 1981 in Oxford, where he had spent 13 years of his career from 1954 until his retirement in 1967 at the University of Oxford.
Edward Calvin Kendall was an American chemist. In 1950, Kendall was awarded the Nobel Prize for Physiology or Medicine along with Swiss chemist Tadeusz Reichstein and Mayo Clinic physician Philip S. Hench, for their work with the hormones of the adrenal gland. Kendall did not only focus on the adrenal glands, he was also responsible for the isolation of thyroxine, a hormone of the thyroid gland and worked with the team that crystallized glutathione and identified its chemical structure.
Alexander Robertus Todd, Baron Todd of Trumpington was a Scottish biochemist whose research on the structure and synthesis of nucleotides, nucleosides, and nucleotide coenzymes gained him the Nobel Prize for Chemistry.
Sir Walter Norman Haworth FRS was a British chemist best known for his groundbreaking work on ascorbic acid while working at the University of Birmingham. He received the 1937 Nobel Prize in Chemistry "for his investigations on carbohydrates and vitamin C". The prize was shared with Swiss chemist Paul Karrer for his work on other vitamins.
Sir Ernst Boris Chain, FRS was a German-born British biochemist, and a 1945 co-recipient of the Nobel Prize for Physiology or Medicine for his work on penicillin.
The Sir William Dunn Professorship of Biochemistry is the senior professorship in biochemistry at the University of Cambridge. The position was established in 1914 by the trustees of the will of Sir William Dunn, banker, merchant and philanthropist.
Juda Hirsch Quastel, was a British-Canadian biochemist who pioneered diverse research in neurochemistry, soil metabolism, cellular metabolism, and cancer.
Norman Wingate (Bill) Pirie FRS, was a British biochemist and virologist who, along with Frederick Bawden, discovered that a virus can be crystallized by isolating tomato bushy stunt virus in 1936. This was an important milestone in understanding DNA and RNA.
Sir William Bate Hardy, FRS was a British biologist and food scientist. The William Bate Hardy Prize is named in his honour.
Dorothy Mary Moyle Needham FRS was an English biochemist known for her work on the biochemistry of muscle. She was married to biochemist Joseph Needham.
Malcolm Dixon was a British biochemist.
Adolphe Guillaume Vorderman was a Dutch physician and scientist whose extensive and scrupulous study of the link between polished rice and Beriberi in the Dutch East Indies in 1897 helped lead to the discovery of vitamins. Adolphe Vorderman was a great-grandfather of British television presenter Carol Vorderman.
Gerrit Grijns, was a Dutch researcher and co-discoverer of vitamin B1 (thiamine) as the successor to the later Nobel Prize winner Christiaan Eijkman.
