John Desmond Bernal FRS[3] (b. 10 May 1901, Nenagh, Co. Tipperary, Ireland, d. London, 15 September 1971) was one of Britain’s best known and most controversial scientists, called "Sage" by his friends, and known for pioneering X-ray crystallography in molecular biology.

His family was Irish, of mixed Italian and Spanish/Portuguese[4] Sephardic Jewish origin on his father's side (his grandfather Jacob Genese, properly Ginesi, had adopted the family name Bernal of his paternal grandmother around 1837).[3] His father Samuel Bernal had been raised as a Catholic in Limerick and after graduating from Albert Agricultural College spent 14 years in Australia before returning to Tipperary to buy a farm Brookwatson near Nenagh where Bernal was brought up. His American mother, née Elizabeth Miller, whose mother was from Antrim, was a graduate of Stanford University and a journalist and had converted to Catholicism.[5][6]
Bernal was educated in England first, for one term, at Stonyhurst College which he hated. Because of this he was moved to Bedford School at the age of thirteen. There, according to Goldsmith, for five years from 1914-1919 he found it 'extremely unpleasant' and most of his fellow students 'bored him' though his younger brother Kevin who was also there was 'some consolation'[7] and Brown claims "he seemed to adjust easily to life" there.[8] In 1919 he went to Emmanuel College, Cambridge University with a scholarship.[9][10]
At Cambridge Bernal studied both mathematics and science for a BA degree in 1922, which he followed by another year of natural sciences. He taught himself the theory of space groups, including the quaternion method; this became the mathematical basis of a lengthy paper on crystal structure for which he won a joint prize with Ronald G.W. Norrish in his third year. Whilst at Cambridge he also became known as "Sage", a nickname given to him about 1920 by a young woman working in C. K. Ogden's Bookshop at the corner of Bridge Street.[11]
After graduation, Bernal began research under Sir William Bragg at the Davy Faraday Laboratory at the Royal Institution[12] in London. In 1924 he determined the structure of graphite and also did work on the crystal structure of bronze.[12] His strength was in analysis as much as experimental method, and his mathematical and practical treatment of determining crystal structure was widely studied, though he also developed an X-ray spectro-goniometer.[13]
In 1927 he was appointed as the first lecturer in Structural Crystallography at Cambridge, becoming the assistant director of the Cavendish Laboratory in 1934. Here he started applying his crystallographic techniques to organic molecules, starting with oestrin and sterol compounds including cholesterol in 1929, forcing a radical change of thinking among sterol chemists.[14] While at Cambridge, he analysed vitamin B1 (1933), pepsin (1934), vitamin D2 (1935), the sterols (1936), and the tobacco mosaic virus (1937).[12] He also worked on the structure of liquid water, showing the boomerang shape of its molecule (1933). It was in his research group in Cambridge that Dorothy Hodgkin started her research. Together, in 1934, they took the first X-ray photographs of hydrated protein crystals using the trick of bathing the crystals in their mother liquor, giving one of the first glimpses of the world of molecular structure that underlies living things.[15] Max Perutz arrived as a student from Vienna in 1936 and started the work on haemoglobin that would occupy him most of his career.
However, Bernal was refused fellowships at Emmanuel and Christ's and tenure by Rutherford, who disliked him,[16] and in 1937, Bernal became Professor of Physics at Birkbeck College, University of London, a department which had been brought to the first rank by Patrick Blackett. The same year he was elected as a Fellow of the Royal Society[3]. After the second world war he established Birkbeck's Biomolecular Research Laboratory in two Georgian houses in Torrington Square with 15 researchers. Aaron Klug worked on ribonuclease whilst Andrew Booth developed some of the earliest computers to help with the computation. Rosalind Franklin joined from King's College and did pioneering work on viruses until her early death in 1957.
His Guthrie lecture of 1947 concentrated on proteins as the basis of life, but it was Perutz, still at Cambridge, who picked up Linus Pauling's leads. In the early '60s, Bernal returned to the subject of the origin of life - analysing meteorites for evidence of complex molecules - and to the topic of the structure of liquids, which he talked about in his Bakerian lecture in 1962.
In the early thirties Bernal had been arguing for peace, but the Spanish civil war changed that. With the outbreak of World War II in 1939, Bernal joined the Ministry of Home Security, where he brought in Solly Zuckerman to carry out the first proper analyses of the effects of enemy bombing and of explosions on animals and people. Their subsequent analysis of the effects of bombs on Birmingham and Hull showed that city bombing produced little disruption and production was only affected by direct hits on factories. A supper of scientists in Soho generated a multi-author book Science in War produced in a month by Allen Lane, one of the guests, arguing that science should be applied in every part of the war effort.[17]
From 1942 he and Zuckerman served as scientific advisers to Lord Louis Mountbatten, the Chief of Combined Operations.[12] Bernal was able to argue on both sides of Project Habbakuk, Pyke's proposal to build huge aircraft landing platforms in the North Atlantic made of ice. He rescued Max Perutz from internment, getting him to perform experiments in a meat store freezer below Smithfield Meat Market.[18] This project indirectly marked his divergence from Zuckerman, when he was recalled from a joint tour of the Middle East investigating the cooperation of army and air force, although the tour established Zuckerman's reputation as a military scientist.[19]
After the disaster of the Dieppe raid, Bernal was determined that these mistakes not be repeated in Operation Overlord, and demonstrated the advantages of an artificial harbour to the participants of the Quebec Conference in 1943 as the only British scientist present. But his main contribution to the Normandy landings was the detailed mapping of the beaches which had to be done without attracting any German attention.[20] His extensive knowledge of the area stemmed from a combination of research in English libraries and personal experience (he had visited Arromanches on previous holidays) combined with the results of aerial surveys that had to spread over much of France.[21]
At Bernal's memorial service, Zuckerman controversially downplayed Bernal's part in the Normandy landings saying that he was not cleared for the highest levels of security.[22] Given Bernal's Marxist and pro-Soviet sympathies it is perhaps remarkable that there has never been any suggestion that he fed any information in that direction.[23] But Brown provides strong evidence[24][25] of Bernal's decisive contributions to the preparation and the success of the invasion.
After helping orchestrate D-Day with work on the structure of the proposed landing sites as well as the bocage countryside beyond, Bernal landed, according to C. P. Snow, at Normandy on the afternoon of D-Day+1 in the uniform of an Instructor-Lieutenant RN to record the effectiveness of the plans. He also assisted boats floundering on the rocks using his knowledge of the area but said: I committed the frightful solecism of not knowing which was port and which side was starboard".[26]
His 1929 work The World, the Flesh and the Devil has been called "the most brilliant attempt at scientific prediction ever made" by Arthur C. Clarke.[27] It is famous for having been the first to propose the so-called Bernal sphere, a type of space habitat intended for permanent residence. The second chapter explores radical changes to human bodies and intelligence and the third discusses the impact of these on society.
In The Social Function of Science (1939) he argued that science was not an individual pursuit of abstract knowledge and that the support of research and development should be dramatically increased. Eugene Garfield, originator of the Science Citation Index, said "his idea of a centralized reprint center was in my thoughts when I first proposed the as yet nonexistent SCI in Science in 1955."[28]
Science in History (1954) is a monumental four-volume attempt to analyse the interaction between science and society. The Origin of Life (1967) gives the current ideas from Oparin and Haldane onwards.
Arriving in Cambridge as a Catholic, Bernal became a socialist as a result of a long night arguing with a friend. As one reviewer says, "This conversion, as complete as St. Paul’s on the road to Damascus, goes some way to account for, but not excuse, Bernal’s blind allegiance for the rest of his life, to the Soviet Union."[29][30] He joined the Communist Party of Great Britain (CPGB) in 1923.[31] His membership evidently lapsed when he returned to Cambridge in 1927 and was not renewed until 1933,[32] and he may have lost his card again shortly after this.[31]
Bernal became a prominent intellectual in political life, particularly in the 1930s. He attended the famous 1931 meeting on the history of science, where he met the Soviets Nikolai Bukharin, and Boris Hessen who gave an influential Marxist account of the work of Isaac Newton. This meeting fundamentally changed his world-view and he maintained sympathy for the Soviet Union and Joseph Stalin. In 1939, Bernal published The Social Function of Science, probably the earliest text on the sociology of science.
After the second world war, although Bernal had been involved in evaluating the effects of atomic attacks against the Soviet Union,[32] he supported the World Congress of Intellectuals for Peace at their congress in Poland in 1948. Afterwards, he wrote a letter to the New Statesman warning that the US was preparing "a war for complete world domination".[33] Consequently, when Bernal was invited to a world peace conference in New York in February 1949, his visa was refused. But he was allowed into France in April for the World Congress of the Partisans of Peace, with Joliot-Curie as president and Bernal as vice-president. The following year the organisation changed its name to the World Peace Council.
On 20 September 1949, after his return from giving a speech strongly critical of western countries at a peace conference in Moscow, the Evening Star newspaper of Ipswich published an interview with Bernal in which he endorsed Soviet agriculture, the "proletarian science" of Trofim Lysenko.[21] The Lysenko affair had erupted in August 1948 when Stalin authorised Lysenko's bogus theory of plant genetics as official Soviet orthodoxy, and refused any deviation. Bernal and the whole British scientific left were damaged by his support for Lysenko's theory, even after many scientists abandoned their sympathy for the Soviet Union.
Under pressure from the burgeoning Cold War, the president of British Royal Society had resigned from the Soviet Academy of Sciences in November 1948.[34] In November 1949, the British Association for the Advancement of Science removed Bernal from membership of its council.[35] Membership in UK radical science groups quickly declined. Unlike some of his socialist colleagues, Bernal persisted in defending the Soviet position on Lysenko. He publicly refused to accept the gaping fissures that the dispute revealed between the study of natural science and dialectical Marxism.[36]
In November 1950, Pablo Picasso, a fellow communist, en-route to a Soviet-sponsored[37] World Peace Congress in Sheffield created a mural in Bernal's flat at the top of No.22 Torrington Square.[38] In 2007 this became part of the Wellcome Trust's collection[39][40] for £250,000.
Throughout the 1950s, Bernal maintained a faith in the Soviet Union as a vehicle for the creation of a socialist scientific utopia. In 1953 he was awarded the Stalin Peace Prize.[41] From 1959-1965 he was president of the World Peace Council.
Bernal had two children (Mike, b.1926 and Egan, b.1930)[2] with his wife Agnes Eileen Sprague (referred to as Eileen),[42] who was a secretary. He married Sprague on 21 June 1922, the day after having been awarded his BA degree. Bernal was 21, Sprague 23. Sprague was described as an active socialist and their marriage 'open' which they both lived up to 'with great gusto'.[43]
In the 1930s he became involved in a long-term relationship with the artist Margaret Gardiner, with whom he had a son Martin Bernal, (born 1937[44]) who became a professor of philosophy and author of the controversial Afrocentric work Black Athena.[45][46] She had had a brief relationship about 1920 with Solly Zuckerman.[25] Gardiner referred to herself as "Mrs. Bernal", though the two never married. Eileen is mentioned as his widow in 1990.[42]
He also had a child (Jane, b.1953) with Margot Heinemann[2] and had a brief intimate relationship with Dorothy Hodgkin, whose scientific research work he mentored.[47]
A fictional portrait of Bernal appears in the novel The Search, an early work of his friend C. P. Snow. He was also said to be the inspiration for the character Tengal in The Holiday by Stevie Smith.
