Royal Medal winners

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.

Sir Humphry Davy, 1st Baronet, (17 December 1778 – 29 May 1829) was a Cornish chemist and inventor who invented the Davy lamp and a very early form of arc lamp. He is also remembered for isolating, by using electricity, several elements for the first time: potassium and sodium in 1807 and calcium, strontium, barium, magnesium and boron the following year, as well as for discovering the elemental nature of chlorine and iodine. Davy also studied the forces involved in these separations, inventing the new field of electrochemistry. Davy is also credited to have been the first to discover clathrate hydrates in his lab.
In 1799 he experimented with nitrous oxide and was astonished at how it made him laugh, so he nicknamed it "laughing gas" and wrote about its potential anaesthetic properties in relieving pain during surgery.Davy was a baronet, President of the Royal Society (PRS), Member of the Royal Irish Academy (MRIA), Fellow of the Geological Society (FGS), and a member of the American Philosophical Society (elected 1810). Berzelius called Davy's 1806 Bakerian Lecture On Some Chemical Agencies of Electricity "one of the best memoirs which has ever enriched the theory of chemistry."

Wilhelm Siegmund Feldberg (19 November 1900 – 23 October 1993) was a German-British physiologist and biologist.

Albert Karl Ludwig Gotthilf Günther , also Albert Charles Lewis Gotthilf Günther (3 October 1830 – 1 February 1914), was a German-born British zoologist, ichthyologist, and herpetologist. Günther is ranked the second-most productive reptile taxonomist (after George Albert Boulenger) with more than 340 reptile species described.

Archibald "Archie" Howie (born 8 March 1934) is a British physicist and Emeritus Professor at the University of Cambridge, known for his pioneering work on the interpretation of transmission electron microscope images of crystals. Born in 1934, he attended Kirkcaldy High School and the University of Edinburgh. He received his PhD from the University of Cambridge, where he subsequently took up a permanent post. He has been a fellow of Churchill College since its foundation, and was President of its Senior Combination Room (SCR) until 2010.
In 1965, with Hirsch, Whelan, Pashley and Nicholson, he published the seminal text Electron Microscopy of Thin Crystals. He was elected to the Royal Society in 1978 and awarded their Royal Medal in 1999. In 1992 he was awarded the Guthrie Medal and Prize. He was elected an Honorary Fellow of the Royal Society of Edinburgh in 1995. He was head of the Cavendish Laboratory from 1989 to 1997.

Antoine Jérôme Balard (30 September 1802 – 30 April 1876) was a French chemist and one of the discoverers of bromine.

Andrew Russell Forsyth, FRS, FRSE (18 June 1858, Glasgow – 2 June 1942, South Kensington) was a British mathematician.
