Ralph H. Fowler
Born in Bristol, he was educated at Blundell's School and graduated from Trinity College, Cambridge as third wrangler in the mathematics tripos before turning to physiology. While still an undergraduate at Trinity College, he derived in 1909 what came to be known as the Langmuir equation. This is closely related to Michaelis-Menten kinetics. In this paper, Hill's first publication, he derived both the equilibrium form of the Langmuir equation, and also the exponential approach to equilibrium. The paper, written under the supervision of John Newport Langley, is a landmark in the history of receptor theory, because the context for the derivation was the binding of nicotine and curare to the "receptive substance" at the neuromuscular junction.
Hill made many exacting measurements of the heat released when skeletal muscles contract and relax. A key finding was that heat is produced during contraction, which requires investment of chemical energy, but not during relaxation, which is passive. His earliest measurements used equipment left behind by the Swedish physiologist Magnus Blix, Hill measured a temperature rise of only 0.003 °C. After publication he learned that German physiologists had already reported on heat and muscle contraction and he went to Germany to learn more about their work. He continually improved his apparatus to make it more sensitive and to reduce the time lag between the heat released by the preparation and its recording by his thermocouple.
Hill is regarded, along with Hermann Helmholtz, as one of the founders of biophysics.
While a student he had enrolled in the Officers Training Course; he was a crack shot. In 1914, at the outbreak of World War I, Hill because the musketry officer of the Cambridgeshire Regiment. The British made no effort to make use of their scientists. At the end of 1915, while home on leave he was asked by Horace Darwin from the Ministry of Munitions to come for a day to advise them on how to train anti-aircraft gunners. On site, Hill immediately proposed a simple two mirror method to determine airplane's heights. Transferred to Munitions, he realized that the mirrors could measure where smoke shells burst and if he fit this data with the equations describing a shell's flight they could provide accurate range tables for anti-aircraft guns. To measure and compute he assembled a team of men too old for conscription, Ralph H. Fowler (a wounded officer), and lads too young for service including Douglas Hartree and Arthur Milne. Someone dubbed his motley group "Hill's Brigands", which they proudly adopted. Later in the war they also worked on locating enemy planes from their sound. He sped between their working sites on his beloved motorcycle. At the end of the war Major Hill issued certificates to more than one hundred Brigands. He was awarded an OBE.
Hill returned briefly to Cambridge in 1919 before taking the chair in physiology at the Victoria University of Manchester in 1920 in succession to William Stirling. Using himself as the subject —he ran every morning from 7:15 to 10:30 — he showed that running a dash relies on energy stores which afterwards are replenished by increased oxygen consumption. Paralleling the work of German Otto Fritz Meyerhof, Hill elucidated the processes whereby mechanical work is produced in muscles. The two shared the 1922 Nobel Prize in Physiology and Medicine for this work. Hill introduced the concepts of maximal oxygen uptake and oxygen debt in 1922.
In 1923 he succeeded Ernest Starling as professor of physiology at University College London, a few years later becoming a Royal Society Research professor there, where he remained until retirement in 1951. In 1933, he became with Lord Beveridge and Lord Rutherford a founder member and vice-president of the Academic Assistance Council (which in 1936 became the Society for the Protection of Science and Learning). By the start of the Second World War, the organisation had saved 900 academics (18 of whom went on to win Nobel Prizes) from Nazi persecution. He prominently displayed in his laboratory a toy figure of Adolf Hitler with saluting arm upraised, which he explained was in gratitude for all the scientists Germany had expelled, some of whom were now working with him. Hill believed that "Laughter is the best detergent for nonsense".
In 1935 he served with Patrick Blackett and Sir Henry Tizard on the committee that gave birth to radar. He was also biological secretary of the Royal Society; William Henry Bragg was president. Both had been frustrated by the delay in putting scientists to work in the previous war. The Royal Society collated a list of scientists and Hill represented the Society at the Ministry of Labor. When the war came Hill led a campaign to liberate refugee scientists who had been interned. He served as an independent Member of Parliament (MP) for Cambridge University from 1940 to 1945. In 1940 he was posted to the British Embassy in Washington to promote war research in the still neutral United States. He was authorized to swap secrets with the Americans, but this could not work: how do you place a value on another's secret? Hill saw the answer and persuaded the British to show the Americans everything they were working on (except for the atomic bomb). The mobilization of Allied scientist was one of the major successes in the war.
After the war he rebuilt his laboratory at University College and vigorously carried on research. In 1951 his advocacy was rewarded by the establishment of a Biophysics Department under his leadership. In 1952 he became head of the British Association for the Advancement of Science and Secretary General of the International Union of Scientific Organizations. He was President of the Marine Biological Association from 1955 to 1960. In 1967 he retired to Cambridge where he gradually lost the use of his legs. He died "held in the greatest affection by more than a hundred scientific descendants all over the world".
In 1913 he married Margaret Keynes (1885-1974), daughter of the economist John Neville Keynes, and sister of the economist John Maynard Keynes and the surgeon Geoffrey Keynes. They had two sons and two daughters:
On 9 September 2015 an English Heritage Blue plaque was erected at Hill's former home, 16 Bishopswood Road, Highgate, where he had lived from 1923-1967. Since then the house had been divided into flats and owned by Highgate School, where Hill was a Governor from 1929-1960. It has now been sold, redeveloped and renamed as Hurstbourne. In Hill's time, according to his grandson Nicholas Humphrey, regular guests at the house included 18 exiled Nobel laureates, his brother-in-law, the economist John Maynard Keynes, and friends Stephen Hawking and Sigmund Freud. After-dinner conversations in the drawing room would inevitably involve passionate debates about science or politics. “Every Sunday we would have to attend a tea party at grandpa’s house and apart from entertaining some extraordinary guests, he would devise some great games for us, such as frog racing in the garden or looking through the lens of a (dissected) sheep’s eye.” Sir Ralph Kohn FRS who proposed the Blue plaque, said: “The Nobel Prize winner A. V. Hill contributed vastly to our understanding of muscle physiology. His work has resulted in wide-ranging application in sports medicine. As an outstanding Humanitarian and Parliamentarian, he was uncompromising in his condemnation of the Nazi regime for its persecution of scientists and others. A. V. Hill played a crucial role in assisting and rescuing many refugees to continue their work in this country.”

The 1926 Alabama gubernatorial election took place on November 2, 1926, in order to elect the Governor of Alabama. Democratic incumbent William W. Brandon was term-limited, and could not seek a second consecutive term.1940 Cambridge University by-election
The Cambridge University by-election, 1940 was a parliamentary by-election for the British House of Commons constituency of Cambridge University on 23 February 1940. Cambridge University was a two-member constituency.Archibald Hill Carmichael
Archibald Hill Carmichael (June 17, 1864 – July 15, 1947) was an American Democratic politician who represented Alabama's 8th congressional district in the United States House of Representatives from November 1933 to January 1937.Bernard Katz
Sir Bernard Katz, FRS (26 March 1911 – 20 April 2003) was a German-born Australian physician and biophysicist, noted for his work on nerve physiology. He shared the Nobel Prize in physiology or medicine in 1970 with Julius Axelrod and Ulf von Euler. He was knighted in 1969.Central governor
The central governor is a proposed process in the brain that regulates exercise in regard to a neurally calculated safe exertion by the body. In particular, physical activity is controlled so that its intensity cannot threaten the body’s homeostasis by causing anoxic damage to the heart muscle. The central governor limits exercise by reducing the neural recruitment of muscle fibers. This reduced recruitment causes the sensation of fatigue. The existence of a central governor was suggested to explain fatigue after prolonged strenuous exercise in long-distance running and other endurance sports, but its ideas could also apply to other causes of exertion-induced fatigue.
The existence of a central governor was proposed by Tim Noakes in 1997, but a similar idea was suggested in 1924 by Archibald Hill.
In contrast to this idea is the one that fatigue is due to peripheral ‘limitation’ or ‘catastrophe’. In this view, regulation by fatigue occurs as a consequence of a failure of homeostasis directly in muscles.Edward B. Almon
Edward Berton Almon (April 18, 1860 – June 22, 1933) was an American, and a Democratic member of the United States House of Representatives who represented northwest Alabama's 8th congressional district.Hill equation (biochemistry)
In biochemistry and pharmacology, the Hill equation refers to two closely related equations that reflect ligands binding to macromolecule. The distinction between the two equations is whether they measure occupancy (the fraction of a macromolecule saturated by ligand) or response (the physiological output of the system, such as muscle contraction). Both equations are a function of the ligand concentration. As the Hill equation is formally equivalent to the Langmuir isotherm, it is sometimes referred to as the Hill-Langmuir equation. The International Union of Basic and Clinical Pharmacology (IUPHAR) has proposed to cement this subtle distinction and define separately the Hill-Langmuir equation, which reflects occupancy of receptors by ligands, and the Hill equation, which reflects (cellular or tissue) response to the ligand. This article will use the IUPHAR convention, to allow more clarity. A slight, yet subtle, distinction is made between the Hill-Langmuir equation, which reflects occupancy of receptors by ligands, and the Hill equation, which reflects (cellular or tissue) response to the ligand.
The Hill-Langmuir equation was originally formulated by Archibald Hill in 1910 to describe the sigmoidal O2 binding curve of haemoglobin.The binding of a ligand to a macromolecule is often enhanced if there are already other ligands present on the same macromolecule (this is known as cooperative binding). The Hill-Langmuir equation is useful for determining the degree of cooperativity of the ligand(s) binding to the enzyme or receptor. The Hill coefficient provides a way to quantify the degree of interaction between ligand binding sites.The Hill equation (for response) is important in the construction of dose-response curves.Ijaw languages
The Ijaw languages (), also spelt Ịjọ, are the languages spoken by the Ijo people in southern Nigeria.John Sparkman
John Jackson Sparkman (December 20, 1899 – November 16, 1985) was an American jurist and politician from the state of Alabama. A Southern Democrat, Sparkman served in the United States House of Representatives and the United States Senate from 1937 until 1979. He was also the Democratic Party's nominee for Vice President in the 1952 presidential election.
Born in Morgan County, Alabama, Sparkman established a legal practice in Huntsville, Alabama after graduating from the University of Alabama School of Law. He won election to the House in 1936 and served as House Majority Whip in 1946. He left the House in 1946 after winning a special election to succeed Senator John H. Bankhead II. While in the Senate, he helped establish Marshall Space Flight Center and served as the chairman of several committees.
Sparkman served as Adlai Stevenson II's the running mate in the 1952 presidential election, but they were defeated by the Republican ticket of Dwight D. Eisenhower and Richard Nixon.
Known as a segregationist proponent during the Civil Rights era, Sparkman was a regular voter against civil rights legislation and condemned the "judicial usurpation" of the Supreme Court decision of Brown v. Board of Education, Sparkman signed the 1956 Southern Manifesto, which pledged opposition to racial integration and promised to use "all lawful means" to fight the ruling that put court power behind the integration of public institutions.
He became the longest-serving Senator from Alabama in 1977. Sparkman chose not to seek re-election in 1978 and retired from public office the following year.Keynes family
The Keynes family ( KAYNZ) is an English family that has included several notable economists, writers, and actors, perhaps the most famous of which was the economist John Maynard Keynes.List of Nobel laureates affiliated with University College London
University College London (UCL) is one of the two founding colleges of the University of London. There have been 33 Nobel Prize laureates amongst UCL’s alumni and current and former staff. UCL has the most Nobel affiliations among colleges and schools of the University of London, which has produced as many as 72 Nobelists till 2010.List of Nobel laureates in Physiology or Medicine
The Nobel Prize in Physiology or Medicine (Swedish: Nobelpriset i fysiologi eller medicin) is awarded annually by the Swedish Karolinska Institute to scientists and doctors in the various fields of physiology or medicine. It is one of the five Nobel Prizes established by the 1895 will of Alfred Nobel (who died in 1896), awarded for outstanding contributions in chemistry, physics, literature, peace, and physiology or medicine. As dictated by Nobel's will, the award is administered by the Nobel Foundation and awarded by a committee that consists of five members and an executive secretary elected by the Karolinska Institute. While commonly referred to as the Nobel Prize in Medicine, Nobel specifically stated that the prize be awarded for "physiology or medicine" in his will. Because of this, the prize can be awarded in a broader range of fields. The first Nobel Prize in Physiology or Medicine was awarded in 1901 to Emil Adolf von Behring, of Germany. Each recipient receives a medal, a diploma and a monetary award that has varied throughout the years. In 1901, von Behring received 150,782 SEK, which was equal to 7,731,004 SEK in December 2008. The award is presented in Stockholm at an annual ceremony on 10 December, the anniversary of Nobel's death.Laureates have won the Nobel Prize in a wide range of fields that relate to physiology or medicine. As of 2009, 8 Prizes have been awarded for contributions in the field of signal transduction by G proteins and second messengers, 13 have been awarded for contributions in the field of neurobiology and 13 have been awarded for contributions in intermediary metabolism. In 1939 Gerhard Domagk, a German, was not allowed by his government to accept the prize. He later received a medal and diploma, but not the money. As of 2018, the prize has been awarded to 216 individuals, twelve of them were women: Gerty Cori (1947), Rosalyn Yalow (1977), Barbara McClintock (1983), Rita Levi-Montalcini (1986), Gertrude B. Elion (1988), Christiane Nüsslein-Volhard (1995), Linda B. Buck (2004), Françoise Barré-Sinoussi (2008), Elizabeth H. Blackburn (2009), Carol W. Greider (2009), May-Britt Moser (2014) and Tu Youyou (2015).
There have been nine years in which the Nobel Prize in Physiology or Medicine was not awarded (1915–1918, 1921, 1925, 1940–1942). There were also five years for which the Nobel Prize in Physiology or Medicine was delayed for one year. The Prize was not awarded in 1914, as the Nobel Committee for Physiology or Medicine decided that none of that year's nominations met the necessary criteria, but was awarded to Robert Bárány in 1915 and counted as the 1914 prize. This precedent was followed for the 1922 prize awarded to Archibald Hill and Otto Fritz Meyerhof in 1923,, the 1926 prize awarded to Johannes Fibiger in 1927, the 1938 prize awarded to Corneille Heymans in 1939,, and the 1943 prize awarded to Henrik Dam and Edward Adelbert Doisy in 1944.Walter Morley Fletcher
Sir Walter Morley Fletcher, (21 July 1873 – 7 June 1933) was a British physiologist and administrator. Fletcher graduated from Trinity College, Cambridge and was most significant in his administration of the Medical Research Council (MRC) during the interwar years. Under his guidance, the MRC focused its funding on basic scientific research at the expense of clinical research but he made Britain a leader in biomedical research in the period.
