80-724: Max Ferdinand Perutz OM CH CBE FRS (19 May 1914 – 6 February 2002) was an Austrian-born British molecular biologist , who shared the 1962 Nobel Prize for Chemistry with John Kendrew , for their studies of the structures of haemoglobin and myoglobin . He went on to win the Royal Medal of the Royal Society in 1971 and the Copley Medal in 1979. At Cambridge he founded and chaired (1962–79) The MRC Laboratory of Molecular Biology (LMB), fourteen of whose scientists have won Nobel Prizes. Perutz

160-501: A 1,000-ton model, and that it was expected to take eight men fourteen days to build it. The Chief of Combined Operations (CCO) responded that Churchill had invited the Chiefs of Staff Committee to arrange for an order to be placed for one complete ship at once, with the highest priority, and that further ships were to be ordered immediately if it appeared that the scheme was certain of success. The Canadians were confident about constructing

240-502: A certain amount of deck covering might be ripped off, but could be repaired by some kind of flexible matting. It would be more difficult to deal with bomb holes in the centre portion, though the roof over the aircraft hangars would be made blast proof against 1,000 kg bombs. Bernal considered that no one could say whether the larger Habakkuk II was a practical proposition until a large-scale model could be completed and tested in Canada in

320-491: A chemistry undergraduate at the University of Vienna and completed his degree in 1936. Made aware by lecturer Fritz von Wessely of the advances being undertaken at the University of Cambridge into biochemistry by a team led by Gowland Hopkins , he asked Professor Mark , who was soon to visit Cambridge, to make inquiries of Hopkins about whether there would be a place for him. Mark forgot, but had visited J.D. Bernal , who

400-532: A completed ship in 1944. By May the problem of cold flow had become serious and it was obvious that more steel reinforcement would be needed, as well as a more effective insulating skin around the vessel's hull. This caused the cost estimate to grow to £2.5 million. In addition, the Canadians had decided that it was impractical to attempt the project "this coming season". Bernal and Pyke were forced to conclude that no Habakkuk vessel would be ready in 1944. Pyke

480-486: A floating island could be made of ice. A German scientist, A. Gerke from Waldenburg, had proposed the idea and carried out some preliminary experiments on Lake Zurich in 1930. The idea was a recurring one: in 1940 an idea for an ice island was circulated around the Admiralty , but was treated as a joke by officers, including Nevil Shute , who circulated a memorandum that gathered ever more caustic comments. The document

560-677: A grant from the Rockefeller Foundation to continue his research. The application was accepted in January 1939 and with the money Perutz was able to bring his parents from Switzerland to England in March 1939. On the outbreak of World War II, Perutz was rounded up along with other persons of German or Austrian background , and sent to Newfoundland (on orders from Winston Churchill). After being interned for several months he returned to Cambridge. Because of his pre-War research into

640-663: A mixture of water and woodpulp that when frozen was stronger than plain ice, was slower-melting and would not sink. Developed by his government group and named after Pyke, it has been suggested that Pyke was inspired by Inuit sleds reinforced with moss. This is probably apocryphal, as the material was originally described in a paper by Mark and Hohenstein in Brooklyn. Pykrete could be machined like wood and cast into shapes like metal, and when immersed in water formed an insulating shell of wet wood pulp on its surface that protected its interior from further melting. However, Perutz found

720-471: A naval officer, Lieutenant Commander Douglas Adshead-Grant , who was provided by Perutz with rods of ice and pykrete packed with dry ice in thermos flasks and large blocks of ice and pykrete. Grant demonstrated the comparative strength of ice and pykrete by firing bullets into both blocks: the ice shattered, but the bullet rebounded from the pykrete and hit the Chief of Imperial General Staff Sir Alan Brooke in

800-740: A neck ribbon (as a necklet ), while women wear theirs on a ribbon bow pinned to the left shoulder, and aides-de-camp may wear the insignia on their aiguillettes . Since 1991, the insignia must be returned upon the recipient's death. number appointment There have been no honorary members of the Order of Merit since the death of the last such member, Nelson Mandela , in December 2013.

960-430: A problem: ice flows slowly, in what is known as plastic flow , and his tests showed that a pykrete ship would slowly sag unless it was cooled to −16 °C (3 °F). To accomplish this the ship's surface would have to be protected by insulation, and it would need a refrigeration plant and a complicated system of ducts. Perutz proceeded to conduct experiments on the viability of pykrete and its optimum composition in

1040-415: A runway and hollowed out to shelter aircraft. From New York Pyke sent the proposal via diplomatic bag to COHQ, with a label forbidding anyone apart from Mountbatten from opening the package. Mountbatten in turn passed Pyke's proposal on to Churchill , who was enthusiastic about it. Pyke was not the first to suggest a floating mid-ocean stopping point for aircraft, nor even the first to suggest that such

1120-514: A secret location underneath Smithfield Meat Market in the City of London . The research took place in a refrigerated meat locker behind a protective screen of frozen animal carcasses. The decision was made to build a large-scale model at Jasper National Park in Canada to examine insulation and refrigeration techniques, and to see how pykrete would stand up to artillery and explosives. Large ice blocks were constructed at Lake Louise, Alberta , and

1200-559: A silver nine-pointed breast star with the image of Minerva at its centre, along with a "straw-coloured" sash worn across the chest from the right shoulder. The motto of the Order would be "Omnia posthabita scientiae" (in Latin , 'Everything comes after science'). Once the King's proposal was made public, however, arguments within intellectual circles over who would be most deserving of the new order grew so heated that George ultimately dropped

1280-400: A small prototype was constructed at Patricia Lake, Alberta , measuring 60 by 30 feet (18 metres by 9 metres), weighing 1,000 tons and kept frozen by a one-horsepower motor. The work was done by conscientious objectors who did alternative service of various kinds instead of military service. They were never told what they were building. Bernal informed COHQ that the Canadians were building

1360-608: A vessel for 1944. The necessary materials were available to them in the form of 300,000 tons of wood pulp, 25,000 tons of fibreboard insulation, 35,000 tons of timber and 10,000 tons of steel. The cost was estimated at £700,000. Meanwhile Perutz had determined via his experiments at Smithfield Market that the optimum structural properties were given by a mixture of 14 per cent wood pulp and 86 per cent water. He wrote to Pyke in early April 1943 and pointed out that if certain tests were not completed in May, there would be no chance of delivering

1440-569: Is a reference to the project's ambitious goal: Behold ye among the heathen, and regard, and wonder marvellously: for I will work a work in your days, which ye will not believe, though it be told you. Habakkuk 1:5 David Lampe, in his book, Pyke, the Unknown Genius , states that the name was derived from Voltaire 's Candide and was misspelled by Pyke's Canadian secretary. However, the word does not actually appear in Candide , so this

1520-587: Is an order of merit for the Commonwealth realms , recognising distinguished service in the armed forces, science, art, literature, or the promotion of culture. Established in 1902 by Edward VII , admission into the order remains the personal gift of its Sovereign—currently Edward VII's great-great-grandson Charles III —and is restricted to a maximum of 24 living recipients from the Commonwealth realms, plus honorary members. While all members are awarded

1600-469: Is probably inaccurate. In early 1942 Pyke and Bernal called in Max Perutz to determine whether an icefloe large enough to withstand Atlantic conditions could be built up fast enough. Perutz pointed out that natural icebergs have too small a surface above water for an airstrip, and are prone to suddenly rolling over. The project would have been abandoned if it had not been for the invention of pykrete ,

1680-631: The Dominions of the British Empire became independent countries within the empire, equal in status to the UK, the Order of Merit continued as an honour open to all these realms and, in many, became a part of their newly developing national honours systems. The order's statutes were amended in 1935 to include members of the Royal Air Force and, in 1969, the definition of honorary recipients

1760-488: The King's College laboratory of Sir John Randall . This report contained X-ray diffraction images taken by Rosalind Franklin that proved to be crucial in coming to the double-helix structure. Perutz did this without Franklin's knowledge or permission, and before she had a chance to publish a detailed analysis of the content of her unpublished progress report. Later this action was criticised by Randall and others, in view of

1840-661: The Lieutenant Governor of Nova Scotia , stated that the Order of Merit was the highest civilian award for merit a Canadian could receive. Some orders of precedence are as follows: Order of wear Project Habakkuk Project Habakkuk or Habbakuk (spelling varies) was a plan by the British during the Second World War to construct an aircraft carrier out of pykrete , a mixture of wood pulp and ice , for use against German U-boats in

1920-467: The Quebec Conference in 1943 Lord Louis Mountbatten brought a block of pykrete along to demonstrate its potential to the admirals and generals who accompanied Winston Churchill and Franklin D. Roosevelt . Mountbatten entered the project meeting with two blocks and placed them on the ground. One was a normal ice block and the other was pykrete. He then drew his service pistol and shot at

2000-539: The Royal Academy of Arts , advised against the new order, primarily because of its selection process. It was Victoria's son Edward VII who eventually founded the Order of Merit on 26 June 1902 (the date for which his coronation had been originally scheduled ) as a means to acknowledge "exceptionally meritorious service in Our Navy and Our Army, or who may have rendered exceptionally meritorious service towards

2080-746: The Royal Society in 1971, appointed a Member of the Order of the Companions of Honour in 1975, received the Copley Medal in 1979 and became a Member of the Order of Merit in 1988. Perutz was made a Member of the German Academy of Sciences Leopoldina in 1964, received an Honorary doctorate from the University of Vienna (1965) and received the Wilhelm Exner Medal in 1967. He was elected to EMBO Membership in 1964. The European Crystallographic Association established

2160-644: The University of York . Gisela was a refugee from Germany (she was a Protestant whose own father had been born Jewish). He died on 6 February 2002 and his ashes were interred with his parents Hugo Perutz and Dely Perutz in the Parish of the Ascension Burial Ground in Cambridge. Gisela died on 17 December 2005 and her ashes were interred in the same grave. Member of the Order of Merit The Order of Merit (French: Ordre du Mérite )

2240-675: The MRC. In his later years, Perutz was a regular reviewer/essayist for The New York Review of Books on biomedical subjects. Many of these essays are reprinted in his 1998 book, I wish I had made you angry earlier . In August 1985, The New Yorker published his account of his experiences as an internee during World War II, titled "That Was the War: Enemy Alien". Perutz won the Lewis Thomas Prize for Writing about Science in 1997. A collection of Perutz's correspondence

2320-666: The Max Perutz Prize, named in his honour. In 1980, Perutz was invited to deliver one of the six lectures for the Royal Institution Christmas Lectures on The Chicken, the Egg and the Molecules . In 1942, Perutz married Gisela Clara Mathilde Peiser (1915–2005), a medical photographer. They had two children, Vivien (b. 1944), an art historian; and Robin (b. 1949), a professor of chemistry at

2400-592: The Order of Merit is open to the citizens of 15 countries, each with their own system of orders, decorations, and medals, the order's place of precedence varies from country to country. While, in the United Kingdom, the order's postnominal letters follow those of Knights and Dames Grand Cross of the Order of the Bath , membership in the Order of Merit itself gives members no place in any of the orders of precedence in

As protein crystals were difficult to obtain, he used horse haemoglobin crystals, and began his doctoral thesis on its structure. Haemoglobin was a subject which was to occupy him for most of his professional career. He completed his Ph.D. under Lawrence Bragg in 1940. He applied to Kings and St. John's colleges, and became a member of Peterhouse , on

2800-564: The advancement of Art, Literature and Science". All modern aspects of the order were established under his direction, including the division for military figures. From the outset, prime ministers attempted to propose candidates or lobbied to influence the monarch's decision on appointments. But, the Royal Household adamantly guarded information about potential names. After 1931, when the Statute of Westminster came into effect and

2880-468: The basis of scientific research and, in molecular biology at least, they are not necessarily subject to revision either. For Perutz, Kuhn's notion that science advances in paradigm shifts that are subject to social and cultural pressures is an unfair representation of modern science. These criticisms extended to scientists who attack religion, in particular to Dawkins. Statements which offend people's religious faith were for Perutz tactless and simply damage

2960-649: The basis that it served the best food. He was elected an Honorary Fellow of Peterhouse in 1962. He took a keen interest in the Junior Members, and was a regular and popular speaker at the Kelvin Club, the college's scientific society. When Hitler took over Austria in 1938, Perutz's parents managed to escape to Switzerland, but they had lost all of their money. As a result, Perutz lost their financial support. With his ability to ski, experience in mountaineering since childhood and his knowledge of crystals, Perutz

However, Frederic Leighton , President of

3120-592: The cabinet minister Leopold Amery . Pyke worked at Combined Operations Headquarters (COHQ) alongside Bernal and was regarded as a genius by Mountbatten. Pyke conceived the idea of Habakkuk while he was in the United States organising the production of M29 Weasels for Project Plough , a scheme to assemble an elite unit for winter operations in Norway, Romania and the Italian Alps. He had been considering

3200-449: The changes in the arrangement of the crystals in the layers of a glacier, he was asked for advice on whether if a battalion of commandos were landed in Norway, could they be hidden in shelters under glaciers. His knowledge on the subject of ice then led to him being recruited for Project Habakkuk in 1942. This was a secret project to build an ice platform in the mid-Atlantic, which could be used to refuel aircraft. To that end he investigated

3280-559: The creation of a prototype on Patricia Lake , Jasper National Park , in Alberta , Canada, the project was shelved due to rising costs, added requirements, and the availability of longer-range aircraft and escort carriers which closed the Mid-Atlantic gap that the project was intended to address. Geoffrey Pyke was an old friend of J. D. Bernal and had been recommended to Lord Louis Mountbatten , Chief of Combined Operations , by

3360-535: The crucial argument was that the rapidly increasing range of land-based aircraft rendered floating islands unnecessary." The Habakkuk design received criticism, notably from Sir Charles F. Goodeve , Assistant Controller of Research and Development for the Admiralty during the Second World War. In an article published after the war Goodeve pointed out the large amount of wood pulp that would be required

3440-507: The death of thousands more innocent people, driving us into a world of escalating terror and counter-terror. I do hope that you can use your restraining influence to prevent this happening." Perutz was elected a Fellow of the Royal Society (FRS) in 1954 . In addition to the Nobel Prize for Chemistry in 1962, which he shared with John Kendrew for their respective studies of the structures of haemoglobin and myoglobin, Max Perutz received

3520-414: The first block. It shattered and splintered. Next he fired at the pykrete to give an idea of the resistance of that kind of ice to projectiles. The bullet ricocheted off the block, grazing the trouser leg of Admiral Ernest King , and ended up in the wall. Sir Alan Brooke 's diaries support this account, telling how Mountbatten brought two blocks, one of ice and one of pykrete. After first shooting at

3600-441: The full-size vessel would cost more money and machinery than a whole fleet of conventional aircraft carriers. (The sunken remains of the metal parts of the boat remain there to this day.) NRC President C. J. Mackenzie later said British promoters of Habakkuk were so intimidated by Prime Minister Churchill that they kept this information from him until Mackenzie's next visit to Britain. Mountbatten later listed several reasons why

3680-424: The ice, with a warning to beware of splinters, Mountbatten said "I shall fire at the block on the right to show you the difference". Brooke reported that "the bullet rebounded out of the block and buzzed round our legs like an angry bee". Max Perutz gave an account of a similar incident in his book I Wish I Made You Angry Earlier . A demonstration of pykrete was given at Combined Operations Headquarters (COHQ) by

3760-633: The idea, though he briefly reconsidered it in 1789; on 6 February of that year, he revised the design of the order, with the breast star to have sixteen points, the motto to be the Latin for "Learning improves character" and with membership to include distinguished scientists. Following the Battle of Trafalgar in 1805, First Lord of the Admiralty Charles Middleton, 1st Baron Barham and William Pitt exchanged correspondence concerning

3840-414: The last person so honoured. Honorary members form another group, to which there is no numerical limit, though such appointments are rare; individuals from countries in the Commonwealth of Nations that are not headed by King Charles are therefore considered foreigners, and thus are granted only honorary admissions, such as Nelson Mandela (South Africa) and Mother Teresa (India). Upon admission into

3920-475: The matter; it was recorded in his diary that he met Sir Robert Peel on 16 January 1844 to discuss the "idea of institution of a civil Order of Merit" and, three days later, he conferred with the Queen on the subject. Though nothing came of the idea at the time, the concept did not wither and, more than 40 years later, on 5 January 1888, Prime Minister Robert Gascoyne-Cecil, 3rd Marquess of Salisbury submitted to

4000-638: The melting pykrete in 20 minutes. After attempting to flash freeze leaks with a fire extinguisher and bailing the water with a hand pump, 10 minutes later Hyneman determined that the boat was taking on more water than the pump could remove and they headed back to shore, trailing sloughed portions of newspaper in their wake. They later inferred that it is possible to build a boat out of pykrete, and that pykrete lived up to its purported properties of being bullet-proof, stronger and taking longer to melt than ice. However, they expressed doubt that an aircraft carrier made of pykrete could have survived for long. The conclusion

4080-442: The mid- Atlantic , which were beyond the flight range of land-based planes at that time. The plan was to create what would have been the largest ship ever at 600 metres (1,969 ft) long, which would have been much bigger than even USS Enterprise , the largest naval vessel ever, at 342 metres (1,122 ft) long. The idea came from Geoffrey Pyke , who worked for Combined Operations Headquarters . After promising scale tests and

4160-579: The molecular structure of biological systems. This financial support allowed him to establish the Molecular Biology Unit at the Cavendish Laboratory. Perutz's new unit attracted researchers who realised that the field of molecular biology had great promise; among them were Francis Crick in 1949 and James D. Watson in 1951. In 1953, Perutz showed that diffracted X-rays from protein crystals could be phased by comparing

4240-487: The patterns from crystals of the protein with and without heavy atoms attached. In 1959 he employed this method to determine the molecular structure of the protein haemoglobin , which transports oxygen in the blood. This work resulted in his sharing with John Kendrew the 1962 Nobel Prize for Chemistry . Nowadays the molecular structures of several thousand proteins are determined by X-ray crystallography every year. After 1959, Perutz and his colleagues went on to determine

4320-537: The possible creation of an order of merit, though nothing came of the idea. Later, Queen Victoria , her courtiers , and politicians alike, thought that a new order, based on the Prussian order Pour le Mérite , would make up for the insufficient recognition offered by the established honours system to achievement outside public service, in fields such as art, music, literature, industry and science. Victoria's husband, Albert, Prince Consort , took an interest in

4400-412: The problem of how to protect seaborne landings and Atlantic convoys out of reach of aircraft cover. The problem was that steel and aluminium were in short supply, and were required for other purposes. Pyke decided that the answer was ice, which could be manufactured for just 1% of the energy needed to make an equivalent mass of steel. He proposed that an iceberg, natural or artificial, be levelled to provide

4480-495: The properties of ice as used for ship construction. In the 15 April 2009 episode of the U.S. TV show MythBusters Jamie Hyneman and Adam Savage built a small flat-bottomed boat dubbed Yesterday's News out of a modified version of pykrete, using whole sheets of wet newspaper instead of wood pulp. They successfully piloted the boat in Alaskan waters at a speed of 25 miles per hour (40 km/h), but it began to leak through

4560-478: The prototype constructed in Canada. Perutz wrote that he stayed in Washington D.C. while U.S. Navy engineers evaluated the viability of Habakkuk. He concluded: "The U.S. Navy finally decided that Habakkuk was a false prophet. One reason was [that] the enormous amount of steel needed for the refrigeration plant that was to freeze the pykrete was greater than that needed to build the entire carrier of steel, but

4640-565: The recently invented mixture of ice and woodpulp known as pykrete . He carried out early experiments on pykrete in a secret location underneath Smithfield Meat Market in the City of London . After the War he returned briefly to glaciology, demonstrating how glaciers flow. In 1947, Perutz, with the support of Professor Bragg, was successful in obtaining support from the Medical Research Council (MRC) to undertake research into

4720-447: The reigning monarch of the realms, currently Charles III , with the assistance of his private secretaries; the order has thus been described as "quite possibly, the most prestigious honour one can receive on planet Earth." Within the limited membership is a designated military division, with its own unique insignia; though it has not been abolished, it is currently unpopulated, Louis Mountbatten, 1st Earl Mountbatten of Burma having been

4800-596: The reputation of science, though he did not criticize scientists opposing "demonstrably false" theories such as creationism . He concluded that "even if we do not believe in God, we should try to live as though we did." Within days of the 11 September attacks in 2001, Perutz wrote to British Prime Minister Tony Blair , appealing to him to not respond with military force: "I am alarmed by the American cries for vengeance and concerned that President Bush's retaliation will lead to

4880-514: The results and the honours resulting from this "gift". In an effort to clarify this issue, Perutz later published the report, arguing that it included nothing that Franklin had not said in a talk she gave in late 1951, which Watson had attended. Perutz also added that the report was addressed to an MRC committee created to "establish contact between the different groups of people working for the Council". Randall's and Perutz's labs were both funded by

4960-414: The reverse bears the royal cypher of the reigning monarch in gold. The insignia for the military grouping is distinguished by a pair of crossed swords behind the central disk. The ribbon of the Order of Merit is divided into two stripes of red and blue. The neck ribbon is 50mm in width, while the ribbon bar width is the standard British 32mm size for military or civilian wear. Men wear their badges on

5040-425: The right to use the post-nominal letters OM and wear the badge of the order, the Order of Merit's precedence among other honours differs between countries. In around 1773, George III considered establishing an order of knighthood to be called the "Order of Minerva " with membership restricted to 24 distinguished artists and authors. Knights would be entitled to the post-nominal letters KM , and would wear

5120-535: The shoulder. By the time of the 1943 Quebec Conference the Habakkuk project had won the support of both Churchill and Mountbatten, and was assigned to the National Research Council of Canada because of the cold Canadian winters and Canadians' prior familiarity with ice physics. The small prototype built in 1944 on Patricia Lake near Jasper, Alberta, confirmed the researchers' forecast that

5200-657: The special boat's construction would be expensive and not needed: In addition, Mountbatten himself withdrew from the project. The final meeting of the Habakkuk board took place in December 1943. It was officially concluded that "The large Habbakuk II made of pykrete has been found to be impractical because of the enormous production resources required and technical difficulties involved." The use of ice had actually been falling out of favour before that, and other ideas for " floating islands " had been considered, such as welding Liberty Ships or landing craft together ( Project TENTACLE ). It took three hot summers to completely melt

5280-737: The spring of 1944. He had no doubts about the suitability of pykrete as a material, but said that constructional and navigational difficulties remained to be overcome. The final design of Habakkuk II gave the bergship , as it was called, a displacement of 2.2 million tons. Steam turbogenerators were to supply 33,000 hp (25,000 kW) for 26 electric motors mounted in separate external nacelles (normal, internal ship engines would have generated too much heat for an ice craft). Its armament would have included 40 dual-barrelled 4.5" DP (dual-purpose) turrets and numerous light anti-aircraft guns, and it would have housed an airstrip and up to 150 twin-engined bombers or fighters. According to some accounts, at

5360-474: The structural changes in a number of haemoglobin diseases and how these might affect oxygen binding. He hoped that the molecule could be made to function as a drug receptor and that it would be possible to inhibit or reverse the genetic errors such as those that occur in sickle cell anaemia . A further interest was the variation of the haemoglobin molecule from species to species to suit differing habitats and patterns of behaviour. In his final years Perutz turned to

5440-431: The structure of oxy- and deoxy- haemoglobin at high resolution. As a result, in 1970, he was at last able to suggest how it works as a molecular machine: how it switches between its deoxygenated and its oxygenated states, in turn triggering the uptake of oxygen and then its release to the muscles and other organs. Further work over the next two decades refined and corroborated the proposed mechanism. In addition Perutz studied

5520-507: The study of changes in protein structures implicated in Huntington and other neurodegenerative diseases. He demonstrated that the onset of Huntington disease is related to the number of glutamine repeats as they bind to form what he called a "polar zipper". During the early 1950s, while Watson and Crick were trying to determine the structure of deoxyribonucleic acid (DNA), they were given by Perutz an unpublished 1952 progress report for

5600-451: The vessel became more demanding: it had to have a range of 7,000 miles (11,000 km) and be able to withstand the largest waves recorded, and the Admiralty wanted it to be torpedo-proof, which meant that the hull had to be at least 40 ft (12 m) thick. The Fleet Air Arm decided that heavy bombers should be able to take off from it, which meant that the deck had to be 2,000 ft (610 m) long. Steering also raised problems; it

5680-668: Was "Plausible, but ludicrous." In September 2010 the BBC programme Bang Goes the Theory also attempted to recreate a pykrete boat. A rough hull using 5,000 kilograms (11,000 lb) of hemp fibre pykrete was frozen in a coldstore, then launched in Portsmouth Harbour for a planned trip across the Solent to Cowes . The hull immediately started to leak because of the holes that had been cut in its rear to mount an outboard motor;

5760-571: Was accepted as a member of a three-man team to study the conversion of snow into ice in Swiss glaciers in the summer of 1938. His resulting article for the Proceedings of the Royal Society made him known as an expert on glaciers. Lawrence Bragg, who was Professor of Experimental Physics at the Cavendish, thought that Perutz's research into haemoglobin had promise and encouraged him to apply for

5840-585: Was born in Vienna , the son of Adele "Dely" (Goldschmidt) and Hugo Perutz, a textile manufacturer. His parents were Jewish by ancestry, but had baptised Perutz in the Catholic religion. Although Perutz rejected religion and was an atheist in his later years, he was against offending others for their religious beliefs. His parents hoped that he would become a lawyer, but he became interested in chemistry while at school. Overcoming his parents' objections he enrolled as

5920-487: Was enough to affect paper production significantly. He also claimed that each ship would require 40,000 tons of cork insulation, thousands of miles of steel tubing for brine circulation and four power stations, but that for all those resources (some of which could be used to manufacture conventional ships of more effective fighting power) Habakkuk would be capable of travelling at only 6 knots (11 km/h) of speed. His article also contained extensive derisive comments about

6000-422: Was excluded from the planning for Habakkuk in an effort to secure American participation, a decision that Bernal supported. Pyke's earlier disagreements with American personnel on Project Plough , which had caused his removal from that project, were the main factor in this decision. Naval architects and engineers continued to work on Habakkuk with Bernal and Perutz during the summer of 1943. The requirements for

6080-429: Was expanded to include members of the Commonwealth of Nations that are not realms. The order has always been open to women, Florence Nightingale being the first woman to receive the honour, in 1907. Several individuals have refused admission into the Order of Merit, including Rudyard Kipling , A. E. Housman , and George Bernard Shaw . Prince Philip, Duke of Edinburgh , remains the youngest person ever inducted into

6160-648: Was initially projected that the ship would be steered by varying the speed of the motors on either side, but the Royal Navy decided that a rudder was essential. However, the problem of mounting and controlling a rudder over 100 ft (30 m) high was never solved. Naval architects produced three alternative versions of Pyke's original concept, which were discussed at a meeting with the Chiefs of Staff in August 1943: Air Chief Marshal Portal asked about potential bomb damage to Habakkuk III, and Bernal suggested that

6240-498: Was looking for a research student to assist him with studies into X-ray crystallography. Perutz was dismayed as he knew nothing about the subject. Mark countered by saying that he would soon learn. Bernal accepted him as a research student in his crystallography research group at the Cavendish Laboratory . His father had deposited £500 with his London agent to support him. He learnt quickly. Bernal encouraged him to use

6320-436: Was published posthumously in 2009, titled What a Time I Am Having: Selected Letters of Max Perutz . Perutz attacked the theories of philosophers Sir Karl Popper and Thomas Kuhn and biologist Richard Dawkins in a lecture given at Cambridge on 'Living Molecules' in 1994. He criticised Popper's notion that science progresses through a process of hypothesis formation and refutation, saying that hypotheses are not necessarily

6400-508: Was retrieved just before it reached the First Sea Lord 's inbox. The project's code name was often incorrectly spelled Habbakuk in official documents. This may have been Pyke's error. At least one early unsigned document (apparently written by him) spells it Habbakuk. However, post-war publications by people concerned with the project, such as Perutz and Goodeve, all restore the proper spelling, with one "b" and three "k"s. The name
