Academics of the University of Sheffield

Sir Hans Adolf Krebs, FRS (, German: [hans ˈʔaːdɔlf ˈkʁeːps] ; 25 August 1900 – 22 November 1981) was a German-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 nearly all organisms, including humans, other than anaerobic microorganisms, namely the citric acid cycle and the urea cycle. The former, often eponymously known as the "Krebs cycle", is the sequence of metabolic reactions that allows cells of oxygen-respiring organisms to obtain far more ATP from the food they consume than anaerobic processes such as glycolysis can supply; and its discovery earned Krebs a Nobel Prize in Physiology or Medicine in 1953. With Hans Kornberg, he also discovered the glyoxylate cycle, 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.

Simon Walker (24 January 1958 – 26 February 2004) was a British historian of late-medieval England. Born in Kuala Lumpur, Malaysia, he was educated at Charterhouse School and Magdalen College, Oxford. He was awarded a Prize Fellowship of All Souls College, Oxford where he completed his D.Phil thesis on John of Gaunt. In 1984 he was appointed to a lectureship at the University of Sheffield, and was subsequently promoted to Reader. In 1999 he was appointed a vice-warden of All Souls and gained an Extraordinary Research Fellowship at the College.Walker's work focused on late-medieval political history, more specifically on the relations between nobles and retainers within the framework often referred to as bastard feudalism. His best-known work, The Lancastrian Affinity, 1361–1399 (1990), explored the retinue of John of Gaunt. Walker died of cancer in 2004.

Sir Andrew Watt Kay (14 August 1914 – 1 February 2011) FRSE, FRCPSG, FRCSEd was a Scottish academic surgeon who was Regius Professor of Surgery at the University of Glasgow from 1964 to 1981. He developed the augmented histamine test, which bore his name, and was widely used in the investigation and treatment of peptic ulcer disease. He was knighted for services to surgery. From 1972 to 1974 he served as president of the Royal College of Physicians and Surgeons of Glasgow.
