Pyke came to public attention when he escaped from internment in Germany during [[World War I]]. He had travelled to Germany under a false passport, and was soon arrested and interned.{{sfn|Pyke|2002|loc=''passim''}} During the [[Second World War]], Pyke proposed the newly invented material, [[pykrete]], for the construction of the ship ''[[Project Habakkuk|Habakkuk]]''.<ref name="ODNB">{{cite ODNB |last= Morris |first= Peter JT |url= http://www.oxforddnb.com/view/article/92810 |title= Pyke, Geoffrey Nathaniel Joseph (1893β1948) |edition= revised | year =2004 |accessdate= 7 September 2009|doi= 10.1093/ref:odnb/92810 }}</ref> == Early life == Pyke's father, [[Lionel Edward Pyke]], was a Jewish lawyer who died when Pyke was only five, leaving his family with no money. His mother quarrelled with relatives and made life "hell" for her children. She sent Pyke to [[Wellington College, Berkshire|Wellington]], then a [[Independent school (UK)|public school]] mainly for the sons of Army officers. At his mother's insistence, Pyke maintained the dress and habits of an [[Orthodox Judaism|Orthodox Jew]]. He became an [[atheist]] when he was thirteen.<ref>{{Cite book |last=Hemming |first=Henry |url=https://www.lander.odessa.ua/doc/HenryHemming.pdf |title=The Ingenious Mr. Pyke |publisher=Public Affairs |year=2015 |isbn=978-1-61039-578-6 |location=The United States}}</ref> The persecution he suffered instilled in him a hatred of and contempt for "[[The Establishment]]".{{sfn|Perutz|2002|p=85}} After two years at Wellington, he was withdrawn, tutored privately and then admitted to [[Pembroke College, Cambridge]], to study law.{{sfn|Pyke|2002|pp=16β17}} == First World War == At the outbreak of the First World War, Pyke quit his studies to become a [[war correspondent]]. He persuaded the editor of the [[Daily Chronicle (United Kingdom)|Daily Chronicle]] to send him to Berlin. He used the passport obtained from an American sailor by travelling via Denmark.{{sfn|Lampe|1959|p=21}} In Germany, he conversed with local Germans, and eavesdropped on other people's conversations, witnessing the mobilisation of Germans for war with the [[Russian Empire]].{{sfn|Pyke|2002|pp=31β43}} In early October, 1914, after six days in Germany, Pyke was arrested in his bed-sitting room, and was taken away leaving a letter written in English on his desk.{{sfn|Lampe|1959|p=22}} Confined to a small cell in solitary confinement, he believed that he might not be executed after all; remarking that "the German government was not going to waste 4[[British one penny coin (pre-decimal)|d]] on my keep if it was going to be faced with burial expenses on the fifth day".{{sfn|Pyke|2002|p=73}} During captivity, he reflected on hunger: {{blockquote|Hunger{{spaced ndash}}real hunger{{spaced ndash}}not your going without afternoon tea, or no-eggs-at-breakfast sort of affair{{spaced ndash}}can, when a man is utterly without occupation, make life one continual aching weary desire. If the desire is not satisfied, or does not abate of its own accord (as it very often does), it can have disastrous effects on a man's mind. It has been known to make men think very seriously about the rights of property, and a few have become so unbalanced as to become socialists.{{sfn|Pyke|2002|p=74}}}} During confinement, Pyke longed for books, writing material and socialising. When allowed out for exercise, he moved around the yard and exchanged words with other inmates. He pieced together poems from memory β ''[[Ifβ|If]]'' by [[Rudyard Kipling]] and ''[[Jabberwocky]]'' by [[Lewis Carroll]] β and recited them loudly in the darkness. During this time, Pyke questioned his sanity.{{sfn|Pyke|2002|pp=90β94}} In January 1915, he was transferred to another prison where he was able to mix with other prisoners and buy newspapers, learning that thousands of foreigners had passed through this prison for a period of quarantine before being transferred to the [[Ruhleben internment camp|internment camp at Ruhleben]]. Five days later, he was transferred to a third prison in [[Moabit]], and then to the internment camp at Ruhleben.{{sfn|Pyke|2002|pp=94β103}}{{Refn | group = "lower-alpha" |Lampe gives very few details of Pyke's time in prison, although he mentions a period of 112 days of solitary confinement β 16 weeks.{{sfn|Lampe|1959|p=23}} This is longer than Pyke's 13 weeks{{sfn|Pyke|2002|p=94}} to which might be added a further 10 days at other prisons.}} At Ruhleben, Pyke met fellow graduates from [[Oxford University|Oxford]] and [[Cambridge University|Cambridge]]. They supplied him with extra clothes, food, books and other amenities. Pyke soon became ill and he nearly died of [[double pneumonia]] and food poisoning, but recovered in summer. Despite illness, he thought about the possibility of escape and repeatedly questioned fellow inmates.{{sfn|Lampe|1959|pp=24β29}} Most were pessimistic about escape, but an Englishman, Edward Falk, agreed despite the low success rate of other attempts. Pyke compiled statistical data on previous escapes, and together with Falk, made a decision to escape,{{sfn|Lampe|1959|pp=24β29}} following a regime of calisthenic exercise to prepare.{{sfn|Lampe|1959|pp=24β29}} On the afternoon of 9 July 1915, Pyke and Falk crept into a hut and hid under tennis nets, using glare from the sunset to blind the patrolling guard. Successful, they waited until dark and climbed over the perimeter fences.{{sfn|Lampe|1959|pp=24β29}}{{Refn|group="lower-alpha"|These details only appear in the 2002 reprint, Pyke did not reveal his escape method in the original work published during the war.{{sfn|Pyke|2002|p=150, footnote}}}} Pyke and Falk took a tram into Berlin, buying clothes and camping equipment and then traveled west. Within {{convert|80|mi|km}} of the Dutch border, they decided to walk,{{sfn|Lampe|1959|pp=24β29}} traversing [[barbed wire]] fences and [[Bog|quagmire]]. Approaching the border, they consumed what remained of their food and discarded their equipment apart from some rope made from string, deciding to cross the [[Netherlands|Dutch frontier]]. As they rested, they were discovered by a soldier and tried to talk their way out of the encounter, only to discover the soldier was Dutch and they were already {{convert|50|yd}} inside the Netherlands.{{sfn|Pyke|2002|pp=207β14}} From here, made their way to [[England]]. Pyke visited his news editor to confess that his mission had failed. However, the editor told Pyke that the story of his escape, based on a long telegraph report Pyke had sent from Amsterdam, had become one of the biggest [[Fleet Street]] [[Scoop (term)|scoops]] of the war. Pyke was the first Englishman to get into Germany and out again, and he was encouraged to write a series of articles for the ''Chronicle''.<ref>{{cite news | title = Englishmen Escape From German Camp; Amazing "Walking Tour" From Berlin | publisher = [[The Manchester Guardian]] | page = 4 | date = 26 July 1915 | id = {{ProQuest|475890080}} }}</ref> Pyke refused, citing lost interest in being a war correspondent.{{sfn|Lampe|1959|p=29}} He divided his time between lecturing on his experiences<ref>{{Citation | title = The Chelsea Fair | newspaper = [[The Times]] | date = 15 June 1918 | page = 4 column A}}.</ref> and writing for the [[Cambridge Magazine]], edited by [[Charles Kay Ogden]].<ref name="ODNB" /> Pyke arranged for some food parcels to be sent to friends in Ruhleben; the boxes contained details of his method of escape concealed in false bottoms.

The building is on the corner of Newnham Road and Malting Lane and overlooks the [[Mill Pond]] and [[Sheep's Green]].]] {{main|Malting House School}} Between the First and Second World Wars, Pyke attempted a number of money-making schemes, speculating on the [[commodity market]], using his own system of financial management and working through a number of different [[stockbroker]]s to avoid attention and higher stock broking charges.{{sfn|Lampe|1959|pp=35β36, 51β53}} The Pykes had a son, David Pyke (1921β2001), and Pyke became preoccupied by the question of his son's education. In October 1924, to create an education that differed from his own and promoted curiosity whilst equipping young people to live in the twentieth century,{{sfn|Hemming|2014|pp=120β121}} he set up an infants' school in his Cambridge home. His wife, Margaret, was a strong supporter of the school and its ideas. Pyke recruited a psychologist, [[Susan Sutherland Isaacs]], to run the school, and although Pyke had many original ideas regarding education, he promised her that he would not interfere. Pyke continued with his city speculations which funded the Malting House School. {{blockquote |The greater his gains, the more he invested until he began to see himself and the people who ran the Great Ormond Street office as a gang of economic corsairs, youthful Bloomsbury intellectual buccaneers slashing through the City and coming away with all its money, and with it endowing a worthwhile work. Certainly, no individual in the strange company ever made any noticeable personal profit, and Pyke's high salary was always paid immediately into the Malting House account.{{sfn|Lampe|1959|pp=51β52}}|Lampe}} The [[Malting House School]] was based on the theories of the American philosopher and educationist [[John Dewey]]. It fostered the individual development of children; children were given great freedom and were supported rather than punished. The teachers were seen as observers of the children, who were seen as research workers. For a short time, The Maltings was a critical if not a commercial success; it was visited by many educationists and it was the subject of a film documentary. Pyke had ambitious plans for the school and began to interfere with the day-to-day running, whereupon Susan Isaacs left The Maltings.<ref name = drummond >{{cite web |url = http://ecrp.uiuc.edu/v2n1/drummond.html |title = Comparisons in Early Years Education: History, Fact, and Fiction |work = Early Childhood Research and Practice |first = Mary Jane |last = Drummond |author-link = Mary Jane Drummond |access-date = 30 June 2008 |archive-date = 18 May 2008 |archive-url = https://web.archive.org/web/20080518011041/http://ecrp.uiuc.edu/v2n1/drummond.html |url-status = dead }}</ref> In 1927, Pyke lost all his money and became [[bankrupt]].{{sfn|Lampe|1959|pp=35β36, 51β53}} The Malting House School was forced to close, Margaret Pyke had to take a job as a headmistress's secretary; she left Geoffrey although they were never divorced. Already suffering from periodic fits of [[clinical depression|depression]] and burdened with huge debts to his brokers, he withdrew from normal life altogether and survived on donations from close friends. === Work against antisemitism === In 1934, Pyke opposed the wave of antisemitism in [[Nazi Germany]], citing humanitarian reasons. Pyke campaigned for Christian leaders to make simultaneous public statements condemning the Nazis, raising money to set up an organisation to combat anti-Semitism. He wrote a number of magazine articles on the irrationality of prejudice and started work on a book.{{sfn|Lampe|1959|pp=61β63}} In his published letters and articles, Pyke insisted that it was necessary to collect data and this struck a chord with other thinkers who would β giving full credit for the germ of an idea to Pyke β go on to establish the [[Mass Observation]] project that set out to document the lives of ordinary Britons.{{sfn|Hemming|2014|pp=168β171}} === Voluntary Industrial Aid for Spain === During the [[Spanish Civil War]], Pyke founded the [[Voluntary Industrial Aid for Spain]] (VIAS) organisation, {{sfn|Hemming|2014|pp=173β182}} encouraging individuals with little money to contribute their time and skills instead. This was opposed by trade unionists who believed that unpaid work might set a dangerous precedent, {{sfn|Hemming|2014|pp=173β182}} but Pyke persisted.{{sfn|Hemming|2014|pp=173β182}} By October 1938, twenty-five vehicles had been sent to Spain including two mobile blood transfusion units,{{sfn|Hemming|2014|pp=173β182}} and by the end of the war, more than seventy vehicles had been contributed.{{sfn|Hemming|2014|pp=173β182}} Organised by [[Trade Union]]s, workers were, with the assistance of sympathetic employers who lent the use of machines and premises, able to produce useful items of equipment.<ref>{{Citation | title = Engineers And Spanish War | newspaper = [[The Times]] | date = 7 April 1938 | page = 11 column A}}.</ref><ref>{{Citation | title = Workers' Aid For Spain | newspaper = [[The Guardian]] | place = Manchester, UK | date = 2 June 1938 | page = 6}}.</ref> Pyke also invented a [[sidecar|motorcycle sidecar]] to carry medical supplies or a patient. He raised funds to pay for American-built [[Harley-Davidson]] motorcycles that were then plentifully available second-hand, and persuaded workers to make the sidecars free of charge with the results being sent out to Spain.{{sfn|Lampe|1959|p=66}}{{sfn|Archives of the Trades Union Congress}} Pyke also assisted in arranging for the manufacture of mattresses for the Spanish government,<ref>{{cite web | url = http://contentdm.warwick.ac.uk/cdm/singleitem/collection/scw/id/8814/rec/4 | title = Letter: Voluntary Industrial Aid | work = Warwick Digital Collections | first = Geoffrey | last = Pyke | access-date = 8 July 2017}}</ref> for the collection of redundant horse-drawn [[plough]]s for Spanish farmers, and bundles of [[hand-tool]]s for use by labourers. He published aggressive propaganda brochures pointing out that British workers were not to consider their contributions a form of charity while Spanish people were fighting and dying for their fellow workers.{{sfn|Lampe|1959|p=67}}{{sfn|Archives of the Trades Union Congress}} To answer a shortage of [[dressing (medical)|bandages and dressings]] in Spain, he suggested that sun-dried [[sphagnum moss|peat moss]] sewn into [[muslin]] bags could be used as a substitute for cotton dressings. Soon, moss collected by volunteers in Britain was on its way to Spain.{{sfn|Lampe|1959|pp=67β68}}{{sfn|Archives of the Trades Union Congress}} == Second World War== === Spying on Nazi Germany === In 1939, before the outbreak of [[World War II|the Second World War]], Pyke considered the problem of finding out what the [[German people]] actually thought of the [[Nazi]] regime. His idea was to perform an [[opinion poll]] in secret by sending volunteers to Germany to interview ordinary people. He would train the volunteers personally. The plan was that the interviewers should pose as golfers on a tour of Germany and that interviews should be informal, with the questions being inserted into everyday conversation; the first German city to be targeted would be [[Frankfurt]]. Pyke travelled to Frankfurt where he met [[Peter Raleigh]]. Raleigh suggested that there were enough of Pyke's golfers in Germany to challenge the Frankfurt golf club to a match. Pyke concluded that this would be an excellent idea, and put this new plan into action. By 21 August, Pyke had ten interviewers working in Germany. On 25 August, following hints from contacts at the [[Foreign Office]], Pyke recalled all his agents and they arrived back in England over the following few days.{{sfn|Lampe|1959|pp=70β77}} Pyke's original idea had been to present Hitler with an account of the true feelings of the German people, but this did not materialise with the outbreak of war. Raleigh and [[Patrick Smith (BBC World Service)|Patrick Smith]] did make a broadcast on the newly formed [[BBC World Service]] in which they contrasted the mood in Germany with that in London, and Pyke prepared a report for the [[War Office]].{{sfn|Lampe|1959|pp=77β78}} Pyke tried to generate interest in his opinion poll results and in repeating the exercise in Germany using people from neutral countries. He got little support, but did attract the attention of [[Conservative Party (UK)|Conservative]] [[Member of Parliament]] [[Leo Amery]]. Amery did think that Pyke's idea was worthwhile and privately convinced others including [[Clement Attlee]] and Sir [[Stafford Cripps]]. Pyke's friends concluded that nothing would come of the scheme and persuaded Pyke to let the matter drop.{{sfn|Lampe|1959|pp=79β80}} === Military inventions === Pyke then wrote on [[grand strategy]] and worked on a number of ideas for practical inventions. Inspired by the sight of barrage balloons, he conceived the idea of using them to mount microphones allowing the location of aircraft to be ascertained by triangulation. Pyke was unaware that the development of [[radar]] provided a much better means of achieving this effect.{{sfn|Lampe|1959|pp=81β83}} ==== Operation Plough / First Special Service Force ==== [[File:Screw Propelled Weasle Prototype.jpg|thumb|right|A screw-propelled prototype of the Weasel (probably an Armstead snow motor fitted on a Fordson tractor together with a lightweight driver's cabin)]] [[File:M29 Weasel 3.jpg|thumb|right|The M29 Weasel eventually produced]] With the [[Operation WeserΓΌbung|invasion of Norway]], Pyke considered the problem of transporting soldiers rapidly over snow. He proposed the development of a [[screw-propelled vehicle]] based on an old patent called the Armstead snow motor. This consisted of a pair of lightweight cylinders, shaped like very large artillery shells, to support the weight of the vehicle. These cylinders have a spiral flange that digs into the snow; when the cylinders turn (in opposite directions), the vehicle is propelled forwards.{{sfn|Lampe|1959|pp=91β95}}<ref>{{cite web | url = http://vimeo.com/2638558 | title = Armsted Snow Motors Product Demo | access-date = 24 January 2013 | work = Vimeo | date = 26 December 2008 | quote = The Armstead Snow Motor Company put out this product demo in 1924.}}</ref> Pyke envisaged that a small force of highly mobile soldiers could occupy the attentions of many enemy soldiers who would be required to guard against possible points of attack. Initially, Pyke's idea was rejected. Then, in October 1941, [[Louis Mountbatten, 1st Earl Mountbatten of Burma|Louis Mountbatten]] replaced [[Roger Keyes]] as Chief of [[Combined Operations (United Kingdom)|Combined Operations]]. This changed the character of the department and Mountbatten allowed unusual talents and ideas. [[Conservative Party (UK)|Conservative]] [[Member of Parliament]] [[Leo Amery]] wrote to Mountbatten recommending that Pyke's Norway scheme, originally rejected by Keyes, be re-examined and that Mountbatten should take Pyke onto his staff.{{sfn|Lampe|1959|pp=87β88}} Mountbatten valued Pyke's ideas, and for liberalising other staff, eventually adopted the plan. The scheme became [[Operation Plough]].{{sfn|Lampe|1959|p=97}} When presented to [[Prime Minister]] [[Winston Churchill]], he noted in the minutes of the meeting:{{cquote|Never in the history of human conflict will so few immobilize so many.{{sfn|Lampe|1959|p=111}}|Churchill quoted by Lampe}} Pyke's snow vehicle project was superseded by Canadian development of the Weasel tracked personnel carrier, produced first for the [[United States|American]]-[[Canada|Canadian]] [[commando|commando unit]] the [[First Special Service Force]], which trained first for Norway but was actually deployed in Italy. The US built hundreds of these as the [[M29 Weasel|M29]] vehicle.<ref>{{cite web | url = http://www.soc.mil/swcs/museum/fssf.shtml | title = First Special Service Force | work = US Army JFK Special Warfare Museum | access-date = 3 January 2008 | archive-url = https://web.archive.org/web/20070807055238/http://www.soc.mil/swcs/museum/fssf.shtml | archive-date = 7 August 2007}}</ref> ==== Project Habakkuk ==== {{Main|Project Habakkuk}} In April 1942, Pyke was presented with the problem of how to prevent the icing of ships in Arctic waters. He took the problem to [[Max Perutz]] at the [[Cavendish Laboratory]], [[University of Cambridge|Cambridge]]; Pyke knew that Perutz had previously worked on the physical properties of snow with regard to the difficulties of Operation Plough. Perutz proposed a solution and in a footnote his memorandum noted that: {{blockquote|It is not only this country but the whole world which, as compared with knowledge of other natural phenomena, lacks knowledge of snow and ice. This is fortunate, for whoever gets there first may get a great advantage.{{sfn|Lampe|1959|p=110}}|Perutz quoted by Lampe}} In September 1942, Pyke sent a 232-page memorandum to Mountbatten detailing his ideas.{{Sfn | Lampe | 1959 | p = 127}} It suggested a number of uses for ice and for [[super cooled water]] (water that has been cooled below its freezing point while remaining liquid) and the suggestion of the construction of gigantic [[aircraft carrier]]s from ice that was either frozen naturally or artificially. Whereas conventional aircraft carriers were restricted to relatively small, specialised aircraft, these could launch and land conventional fighters and bombers. As such, they could provide air cover for convoys in mid-Atlantic, staging posts for long flights over seas or as launch pads for [[Normandy Landings|amphibious assaults on France]] or [[Operation Downfall|Japan]]. A biography of Pyke by David Lampe indicates that he had decided to use ice reinforced with wood fibres, but other accounts make it clear that this is not the case.{{sfn|Perutz|1948}} Pyke was not the first to suggest a floating mid-ocean stopping point for aircraft, nor the first to suggest that such a floating island could be made of ice, German scientist Dr. A. Gerke of Waldenburg in Germany proposed the idea and carried out some preliminary experiments in Lake Zurich in 1930.<ref>{{citation |date = 27 February 2008 |publication-date = October 1932 |title = Ice Island in Mid-Atlantic Proposed |journal = [[Modern Mechanix]] |issn = 0025-6587 |format = Weblog |url = http://blog.modernmechanix.com/ice-island-in-mid-atlantic-proposed/ |access-date = 18 February 2009 |archive-date = 24 September 2019 |archive-url = https://web.archive.org/web/20190924082936/http://blog.modernmechanix.com/ice-island-in-mid-atlantic-proposed/ |url-status = dead }}</ref><ref> {{Citation |magazine=[[Popular Science]]|issn=0161-7370|date=September 1932|title=Ocean Airports of Artificial Ice |publisher=[[Bonnier Corporation]] |volume=121|number=3|location=[[Harlan, Iowa]], U.S. |page=33 |access-date=3 March 2019|url=https://books.google.com/books?id=FygDAAAAMBAJ&q=Gerke+von+Waldenburg&pg=PA33 |format=Online at [[Google Books]]}} </ref> Pyke's memorandum included a couple of cover notes. The first requested that Mountbatten should read the suggestions himself before allowing it to fall into the hands of "that damned fool Lushington".{{sfn|Lampe|1959|p=136}} The second, longer, note asked that Mountbatten read the first thirty pages of the memorandum before deciding whether it was worthwhile to continue "It may be gold: it may only glitter. I can't tell. I have been hammering at it too long and am blinded".{{sfn|Lampe|1959|p=128}} Mountbatten handed it to Brigadier Wildman-Lushington, and Lushington with the assistance of [[J. D. Bernal]], concluded that Pyke's main proposals were feasible.{{sfn|Lampe|1959|p=136}}{{sfn|Battersby|2012}} In December 1942, Prime Minister Churchill issued a directive that research on the project should be pressed forward with the highest priority and he expressed the opinion that nature be allowed to do as much of the work as possible.{{sfn|Perutz|1948}}{{sfn|Battersby|2012}} The project to build a large aircraft carrier of pykrete was known as [[Project Habakkuk]], and Pyke was sent to Canada with a personal introduction from [[Winston Churchill]] to [[Mackenzie King]]. While he was away, an Admiralty committee headed by the [[Chief of Naval Construction]] sent a memorandum about Habakkuk to Mountbatten. Pyke returned from Canada. Pyke's original memorandum mentioned other applications for pykrete such as building landing ships for the [[Operation Downfall|prospective invasion of Japan]] and for quickly constructing fortifications at a [[beachhead]] by spraying an existing building with pykrete liquid that would freeze into a thick layer. Many of these ideas relied upon a misplaced faith in the qualities of [[Supercooling|supercooled water]] which he thought could be used as a weapon of war: pumped from a ship it could be used to instantly form bulwarks of ice or even be sprayed directly onto enemy soldiers. However, such ideas were according to [[Max Perutz]], impractical.{{sfn|Perutz|2002|p=90}} In September 1943, Pyke proposed a slightly less ambitious plan for pykrete vessels to be used in support of an [[amphibious assault]]. He proposed a pykrete [[Monitor (warship)|monitor]] {{convert|200|ft}} long and {{convert|50|ft}} wide mounting a single naval [[gun turret]]; this could be self-powered or towed to where it would be used. He also suggested the use of pykrete to make breakwaters and landing stages. At the time, Max Perutz thought the ideas were practical and that the preceding research on pykrete was sufficiently advanced to allow Pyke's plan to be executed.<ref name = "ADM 1/15677">{{Citation| contribution = Proposals and inventions of Mr Geoffrey Pyke; gravity propelled ball bomb, pykrete and power driven rivers| url = http://www.nationalarchives.gov.uk/catalogue/ExternalRequest.asp?RequestReference=ADM1/15677 | number = ADM 1/15677 | title = The Catalogue | publisher = [[The National Archives (United Kingdom)|The National Archives]]}}.</ref> The plan was not put into action, but for the allied [[invasion of Normandy]] a system of preconstructed concrete breakwaters and landing stages called [[Mulberry harbour|Mulberry]] was employed. Pyke's plans hint that he had some knowledge of the Mulberry plans, perhaps through his contacts with [[John Desmond Bernal|Bernal]], who was one of Mulberry's progenitors. ==== Men in pipes ==== In late 1943, Pyke submitted to Mountbatten a memorandum, nearly fifty pages long, explaining his ideas for a solution to the problem of unloading stores from ships where no proper port facilities are available and few roads inland. This circumstance was common in the [[Pacific War]] theatre and fundamental to the 1943 decision to invade France by landing on the beaches of Normandy, with no harbours and a 24-foot tide. Pyke's idea was to use pipes of the type that were used to transport fuel from ship to shore, to move sealed containers that would contain any type of sufficiently small material objects. Pyke suggested that {{convert|4|or|6|in|mm}} pipes would handle smaller equipment and larger objects could be passed through two-foot pipes. Furthermore, there was no reason why the pipes should stop at the shore, they could be extended inland as required. Bernal gave a cautious endorsement to the idea, adding that it would require a great deal of investigation.{{sfn|Lampe|1959|p=164}} Pyke's idea was similar to the cleaning brushes that are sometimes forced along pipes by the pressure of the fluid and to the [[Pipeline inspection gauge|pipeline pigs]] which today are used for cleaning and telemetry. Pyke then proposed that his idea for "Power-Driven Rivers" could be extended to the transport of personnel. The pipes would need to be at least two feet in diameter and the pressures would have to be high. He worked out ideas for supplying the passengers with oxygen and suggested that the problem of [[claustrophobia]] might be alleviated by travelling in pairs and by the use of [[barbiturate]] drugs.{{sfn|Lampe|1959|p=168}} {{blockquote|The whole experience (of riding in a pipe) however should be far less unpleasant, and take very much less time to become used to, than parachute jumping, or being bombed.{{sfn|Lampe|1959|p=168}}|Pyke quoted by Lampe}} Pyke proposed that this system could be used to move people from ship to shore, from island to island, through swamps and over mountains and anywhere where conventional transport was difficult.{{sfn|Lampe|1959|p=168}}<ref>{{Citation | title = Men in Pipeline β The Idea That Was Never Carried Out | newspaper = [[The Guardian]] | place = Manchester, UK | date = 7 March 1951 | page = 8 column G}}.</ref> The idea was never used. == After World War II == After World War II, Pyke's inventions continued. One suggestion for the problems of energy-starved post-war Europe was to propel railway wagons by human muscle power β employing 20 to 30 men on bicycle-like mechanisms to pedal a cyclo-tractor. Pyke reasoned that the energy in a pound of sugar cost about the same as an equivalent energy in the form of coal and that while Europe had plenty of sugar and unemployed people, there was a shortage of coal and oil. He recognised that such a use of human muscle power was in some ways distasteful, but could not see that the logic of arguments about calories and coal were unlikely to be sufficiently persuasive.<ref>{{Citation | series = Europe's Coal Famine | title = I β The Problem Analysed | newspaper = [[The Guardian]] | place = Manchester, UK | date = 20 August 1945 | page = 4 column F}}.</ref><ref>{{Citation | series = Europe's Coal Famine | title = II β A Solution Outlined | newspaper = [[The Guardian]] | place = Manchester, UK | date = 21 August 1945 | page = 4 column F}}.</ref><ref>{{Citation | series = Europe's Coal Famine | title = III β The Organisation of Muscle-Power | newspaper = [[The Guardian]] | place = Manchester, UK | date = 24 August 1945 | page = 4 column F}}.</ref> Pyke was given a commission to look into the problems of the [[National Health Service]] and, characteristically, made his contribution as a part of a [[Dissenting opinion|minority report]].<ref>{{Citation | title = Recruitment And Training of Nurses | newspaper = [[The Times]] | date = 11 September 1947 | page = 5 column F}}.</ref> He remained eager to convey his unconventional ideas, and continued to both write and broadcast them. He campaigned against the death penalty,<ref>{{Citation | title = The Death Penalty | type = letter to the editor | newspaper = [[The Times]] | date = 3 December 1947 | page = 5 column F}}.</ref> and for government support of [[UNICEF]].<ref>{{Citation | title = Helping The Children | type = letter to the editor | newspaper = [[The Times]] | date = 31 January 1948 | page = 5 column E}}.</ref> == Death and legacy == On the evening of Saturday 21 February 1948 in Steele's Road, Hampstead, Pyke shaved his beard and consumed a bottleful of [[sleeping pill]]s. His [[Landlord|landlady]] found his body the following Monday morning.{{sfn|Lampe|1959|pp=205β206}} The coroner gave a verdict of suicide at a moment of mental unbalance.<ref>{{Citation | title = Time |date=March 1948}} mentions that Pyke suffered from leukaemia, but this is not given in other sources.</ref> Before consuming the pills, he had written private letters that made it clear that his death was premeditated.{{sfn|Lampe|1959|loc=Epilogue}} An obituary in ''[[The Times]]'' praised him and lamented his passing, beginning with the words: {{blockquote |The death of Geoffrey Pyke removes one of the most original if unrecognised figures of the present century.<ref>{{Citation | title = Mr Geoffrey Pyke β Fearless Innovator | type = obituary | newspaper = [[The Times]] | date = 26 February 1948 | page = 6 column D}}.</ref>}} John Bernal, who knew Pyke well, wrote: {{blockquote |He remained always the knight-errant, from time to time gathering round him a small band of followers but never a leader of big movements.
