The First World War turned existing scientific and industrial capabilities towards new wartime demands. Germany organised raw-material supplies and recruited researchers for military work. Britain expanded factories and research support. France developed radiology services for wounded soldiers, while the United States established the National Research Council in 1916, before entering the fighting. This was not one team or one invention: governments, researchers, companies and workers had to make different institutions cooperate. [1] [3] [5] [8] [13]
The results included better care and more destructive power—not an uncomplicated story of progress. Medical teams improved access to X-rays and developed ways to supply transfusions. Chemical warfare created new injuries. Factory workers faced dangerous conditions, and some scientists died before they could continue their research. A useful wartime development does not establish that the war was necessary to obtain it or that its benefits outweighed the losses. [6] [7] [11] [15] [17]
Prequel Part 4 followed the decisions that widened the crisis of 1914 into war. Part 5 follows what happened to knowledge and skilled work once the fighting began. The principal period is 1914–1918, examined through selected European and American examples rather than a complete account of every front. We ask how expertise reached a hospital, factory or government office, who controlled its use, and what could survive after the emergency ended.

24 January 1915: The Scientist Had Arrived. The Room Was Not Ready.
Writing to her daughter Irène from Poperinghe, Marie Curie explained why work could not yet begin. The hospital needed a shelter for the radiology car and a partition to create a suitable room within a larger ward. Curie and the equipment were present, but the place in which they would work still required alteration. The letter survives in a published translation reproduced by the American Institute of Physics. [1]
This is not the moment usually chosen to represent scientific achievement. There is no new discovery and no announcement of a prize. Yet the delay exposes the last part of a connection that stories about great minds can miss. Knowledge had reached the hospital without yet becoming a service the hospital could use.
The people preparing the space were not peripheral to that service. Their work made it possible for a medical technique to enter the treatment of particular patients. Nothing in this observation reduces Curie’s contribution. It explains why her contribution needed other contributions around it.
We will return to that unfinished room. First, we must go back to the opening months of the war, when an established discovery encountered an organisation that had not prepared to use it on the necessary scale.
August 1914: The Discovery Was Older Than the Emergency
Curie’s later account describes gathering available apparatus, establishing radiology stations and instructing volunteers in August and September 1914. With Red Cross help, she equipped a car that could carry an X-ray installation to hospitals. It was a response to inadequate provision, not the invention of X-rays during the fighting. [1]
In her 1921 book, La Radiologie et la Guerre, Curie explicitly began with Röntgen’s discovery in 1895 and the medical work developed before the war. The new emergency changed the demand for a technique whose foundations already existed. [7]
This distinction belongs at the centre of our thesis. A sudden expansion in use is not necessarily a sudden invention. A society may possess knowledge for years while providing only limited opportunities to apply it. Crisis can expose that gap and concentrate attention on closing it.
It does not follow that the crisis was the only possible way to close the gap. The hospital needed a useful service because people were injured; the service’s usefulness cannot make those injuries desirable. We can explain the urgency that changed the organisation without treating the catastrophe as a necessary investment.
13 August 1914: Germany Needed to Know What It Had
On 13 August, the Prussian War Ministry established the War Raw Materials Department, usually known by its German initials, KRA. Walther Rathenau became its head following proposals associated with him and Wichard von Moellendorff. The department addressed the supply of materials on which military production depended. [3]
In a lecture delivered in December 1915, Rathenau recalled the first difficulty: officials needed a usable estimate of available stocks, while industrial opinions differed sharply. His account describes an urgent survey of suppliers as a way to establish the broad position. It was the recollection of a participant explaining his undertaking, not an independent audit of everything it achieved. [2]
The task was intellectual without being a laboratory experiment. A country could possess metal, chemicals and factories yet lack a reliable picture of where supplies were located or how long they would last. Gathering information changed what officials could decide.
It did not create more material merely by counting it. The survey made the shortage more intelligible. Substitution, purchasing, production and allocation remained further tasks, each requiring different knowledge and authority.
An Inventory Became a Question of Power
The KRA worked through a combination of state direction and industrial organisations. The German Historical Museum records conflict between priority for armaments and the concerns of authorities responsible for civilian supplies. Coordination did not mean that every need could be met simultaneously. [3]
Rathenau’s lecture also included requisitioning resources from occupied territory among the ways supplies were obtained. His enthusiastic account of national mobilisation must therefore be read alongside the coercion involved. Material reaching a German factory could have been removed from people whose consent had not been sought. [2]
This changes the meaning of an efficient organisation. Efficient for whom, and for which purpose? A department can make a military supply system work better while worsening the position of civilians or an occupied population. Administrative competence does not determine whether the objective it serves is just.
The example also rules out a simple national contrast in which Germany failed because it could not organise expertise. It did organise expertise. The later academic persecution examined in the main series damaged a country with substantial capabilities, not a country that had never learned to coordinate them.
4 October 1914: Reputation Entered the War Too
The manifesto known as the Appeal of the Ninety-Three defended Germany’s conduct and rejected accusations concerning Belgium. Its signatories included prominent figures from scholarship and the arts. Max Planck, Fritz Haber and Adolf von Harnack were among the scientists and institutional leaders associated with the appeal. [4]
The text demonstrates another way intellectual authority could be mobilised. An accomplished scientist’s name could lend credibility to claims about military events, responsibility and national character. The prestige came from one kind of work; the assertions concerned another.
A signature was not independent verification of everything the document asserted. The manifesto’s denials must not be adopted as findings simply because distinguished people endorsed them. Nor does one appeal establish that every scholar held the same view. It records a consequential public intervention by its particular signatories.
Our main series asked how governments listened to scientific advice. Here, the question runs in the opposite direction: how did intellectuals use their authority when judging the government’s cause? Technical distinction did not exempt them from the need to examine evidence outside their own expertise.
A Research Institute Acquired a Different Assignment
The Kaiser Wilhelm Institute for Physical Chemistry and Electrochemistry was placed under military control and redirected towards wartime research. Its institutional history records the death of physicist Otto Sackur in a laboratory explosion in 1914. The demands of mobilisation changed both the work and the risks inside an establishment founded before the war. [5]
The institute subsequently became a centre for chemical-warfare research and protection against chemical attack. Scientists drawn into its wartime projects included James Franck and Otto Hahn. Richard Willstätter contributed to protective equipment. These were organised research relationships, not merely an isolated chemist offering an idea to the army. [5]
Franck’s name connects this prequel with the main series, where we encountered his later protest against Nazi persecution and his participation in the 1945 report on atomic policy. That later history should not be read backwards as proof of one unchanging position throughout his life. People’s choices must be examined in the circumstances in which they made them.
Nor does naming participants assign everyone identical responsibilities. Designing, administering, advising and authorising are different actions. The institution’s military role establishes the setting; individual conduct requires evidence at the individual level.
22 April 1915: A New Attack Did Not Produce a Quick Peace
At Ypres on 22 April 1915, German forces carried out a large-scale chlorine attack against a sector held by French Territorial and Algerian troops. Canadian troops nearby also became involved in the fighting, and another attack struck their positions two days later. This was a major escalation in chemical warfare, not the first appearance of every kind of chemical irritant in military history. [6]
The Haber Institute’s history describes Haber’s expectation that chemical attack might break the trench deadlock and help bring the war to a rapid conclusion in Germany’s favour. That expectation must be distinguished from what followed: the war continued, and chemical warfare expanded. [5] [18]
A weapon can create a severe local crisis without delivering the political or military ending its advocates predict. The opposing side can adapt, acquire protection or respond with weapons of its own. A successful release of a harmful agent and a successful strategy for ending a war are not the same result.
The people exposed were not simply evidence in a contest between competing research programmes. They experienced the consequence that the technical system had been organised to produce. An account of the achievement that stops at the laboratory door excludes what made the undertaking a weapon.
1915: Britain’s Problem Was Also a Production Problem
Britain’s prewar armaments industry had been organised around naval requirements, export orders and a relatively small regular army. The demands of the Western Front required a different scale of supply. Existing establishments expanded, and the shortages associated with the 1915 shell crisis were followed by the Ministry of Munitions and a much larger factory programme. [8]
The central difficulty was not that nobody knew what artillery ammunition was. Known products had to be made in sufficient quantities, with dependable quality, and delivered where needed. More scientific knowledge could help, but expanding an output also required equipment, materials, transport and trained people.
A contract could establish demand without instantly creating those resources. A new building could stand ready while workers or machinery were still unavailable. Increasing one part of the undertaking might reveal a different shortage elsewhere.
This is the wartime extension of the factory story in Prequel Part 2. An experimental result becomes useful through a working organisation. In an emergency, the same connection must be made under tighter time constraints, with far greater consequences when the organisation fails.
The Government Needed Workers—and Restricted Their Choices
The Munitions of War Act of 1915 allowed factories to be designated controlled establishments and restricted workers’ ability to leave through certificates and tribunals. Compulsory dispute procedures and restrictions on strikes formed part of the wartime system. The parliamentary history records that strikes nevertheless continued. An instruction issued by the state did not guarantee universal compliance. [9]
Women entered munitions work in greatly increased numbers. Historic England’s research identifies both the expansion of their employment and the dependence of many factories on their labour. Parliamentary records also show disputes over pay and concern about how the employment of women and less-skilled workers would affect established wage arrangements. [8] [9]
The resulting mobilisation was not simply a queue of people freely volunteering to perform the same work under unchanged conditions. Government authority and workplace bargaining shaped what could be required, what was paid and how an employee could seek a different position.
A national production total can conceal these differences. It measures material completed, not whether those who made it gained security or control over their lives. A society can discover that a previously excluded group is capable of demanding work without automatically granting that group equal standing.
5 December 1917: More Hours Could Produce Less
By December 1917, Lord Sydenham was asking the House of Lords what had been done with the findings of the Health of Munition Workers Committee, appointed in 1915. He cited investigations in which shorter working hours had maintained or improved output and asked whether recommendations on rest and excessive labour were being implemented. [10]
The government’s reply acknowledged revised recommendations and described further changes still under consideration. The exchange did not establish that every workplace had already adopted the proposed limits. It documented the distance between producing evidence, accepting its significance and changing practice. [10]
The findings challenged an attractive but inadequate calculation: multiply people by hours and assume output rises proportionately. People are not machines whose productive contribution continues unchanged as their working day lengthens. The investigations concerned particular jobs and conditions; they do not supply one universal numerical rule for every workplace.
Scientific inquiry was being applied to the organisation of labour itself. Yet even evidence framed in terms of greater production could meet delay. A government could mobilise researchers to discover how work should be organised and still struggle to make its factories follow the implications.
The Danger Did Not Remain at the Front
Factory expansion brought serious hazards. Historic England records 108 deaths in the April 1916 explosion at Faversham and 134 in the disaster at Chilwell. These were deaths associated with production, not casualties caused by enemy soldiers attacking the workers. The distinction places the cost inside the supply undertaking itself. [11]
Counting those losses does not establish that every workplace was equally dangerous or that every accident had the same cause. It establishes that producing the means of war could kill people before the products reached the battlefield. Output alone cannot measure how safely an organisation accomplished its task.
Nor should subsequent production be treated as an answer to the families affected. A factory might resume work and fulfil its orders without reversing a death. Continuity of output and recovery for the people who supplied the labour are different outcomes.
The connection with our original question becomes clearer. A government assembling expertise also needed to protect and sustain the people doing the work. Acquiring additional labour was not an adequate substitute for understanding why existing workers were being injured, exhausted or killed.
1916: Research Support Became an Institutional Responsibility
Returning to Britain’s research organisation, the Department of Scientific and Industrial Research was established as a department in 1916. The Science Museum Group’s institutional record describes its responsibilities for supporting research in universities and technical colleges, developing research organisations and encouraging practical application. Grants and fellowships were among its instruments. [12]
This addressed a problem different from purchasing more of an existing product. Some investigations needed support before anyone could specify the final commercial result. A department could provide a continuing route through which proposed work was considered, instead of leaving every investigator to find an exceptional personal connection.
Establishing that route did not guarantee wise decisions or instant discoveries. Administrators needed to judge proposals, researchers needed time to carry them out, and someone had to decide how the results could be used. The institution made those decisions possible within an organised framework; it did not settle them in advance.
The wartime setting also did not mean that every research question was reducible to a weapon. Industrial and educational capacity could matter over a longer period. Keeping those purposes connected with immediate demands was a continuing problem, not a choice solved merely by naming a department.
1916: America Organised Research Before Entering the Fighting
The National Academy of Sciences organised the National Research Council in 1916. George Ellery Hale helped secure cooperation among scientific societies, universities, industry and government agencies. Wilson approved the preliminary plan on 24 July. The country was still neutral in the European war; scientific preparedness and belligerency did not begin on the same date. [13]
The cooperation involved organisations that already existed. Bringing them into a common undertaking was not the same as creating every laboratory or transferring every researcher into a single federal establishment. The council supplied a means to connect dispersed capabilities.
This is an earlier answer to the question that opened the main series. America’s 1941 research mobilisation did not appear without institutional precedents. The First World War provided experience in coordinating expertise, although the later scale and arrangements still required new decisions.
It would be equally misleading to turn the council into the sole organiser of all American technical work. A coordinating institution operates among other institutions with their own authority and responsibilities. Cooperation can enlarge what they accomplish without making them interchangeable.
6 April 1917: Entry Into War Did Not Complete the Mobilisation
Wilson’s proclamation of 6 April 1917 announced a state of war between the United States and Germany following the congressional resolution. This changed the political circumstances of research and production. It did not instantly complete the projects that a wartime government could now authorise. [14]
The Academy’s history records one revealing delay: a programme of four plants for nitric-acid production, authorised in June 1917 after investigations by several agencies, was not completed until after the war. The record distinguishes the decision to obtain capacity from having that capacity available in time. [13]
A project can therefore belong to a war’s history without having contributed its intended output before the fighting stopped. Money spent and buildings begun are evidence of effort. They are not proof of a delivered military effect.
This is a useful restraint on technological storytelling. Later knowledge of a programme’s achievements makes it tempting to place all of them inside its founding moment. A more accurate account asks when each capability became usable and what was still missing when decisions had to be made.
A Trained Person Could Be Assigned to the Wrong Work
Curie’s postwar account describes radiology specialists initially mobilised into duties unrelated to their expertise. It also recalls physicists guarding bridges and railways before some were redirected into radiological work. The problem was not simply an absence of educated people. Some existed but were being used in places that did not make the best use of their preparation. [7]
An institution can make that mistake without anyone having forgotten how to read a qualification. The authority assigning personnel may not know which hospital needs them; the hospital may not know whom to request. Each office can possess part of the information while the connection remains missing.
Correcting the assignment is not a discovery in physics. It can nevertheless determine whether physical knowledge reaches a patient. The distinction explains why communication and administrative judgement belong within the history of scientific capability.
We should not infer that every specialist should always be exempt from other duties or that a country could meet every competing need. The narrower lesson is that counting trained people does not establish what they are able to contribute. Their assignments and the information connecting those assignments matter.
1917–1918: The Expert Needed to Become a Teacher
Curie reported that the radiology school she helped organise trained about 150 women operators from 1917 to the war’s end. They received assignments, principally in services away from the armies, although some went to military services at their own request. The number describes her account of this training effort, not every radiology worker in France. [7]
Teaching altered the scale of what could be sustained. A service dependent on one expert’s presence cannot be everywhere that expert is needed. Training others can make additional installations useful and reduce the dependence on a single person’s availability.
The students were not merely copies of an expert’s hands. They needed to recognise a problem, understand the apparatus and work with medical colleagues. Repetition without judgement would leave them poorly prepared when an unfamiliar difficulty arose.
That is the educational connection running through this book. Institutions preserve knowledge partly by enabling other people to use and question it. Recruiting an accomplished researcher helps with today’s work; preparing new practitioners helps determine whether the work can continue when that researcher is elsewhere.
November 1917: Blood Could Be Prepared Before the Casualties Arrived
During the fighting at Cambrai in November 1917, the American doctor Oswald H. Robertson used preserved red blood cells at a British casualty clearing station. The U.S. Army’s medical history explains the organisational problem: collecting blood only as casualties arrived limited how much could be done during a rush. Preparing supplies beforehand changed that constraint. [15]
This Robertson should not be confused with the Canadian surgeon Lawrence Bruce Robertson, who also made important wartime contributions to transfusion practice. Neither man invented all the knowledge on which transfusion depended. The history identifies work by several practitioners and earlier laboratory investigators. [15]
The new arrangement connected preparation, preservation, transport and clinical work. The important change was not simply that a doctor knew blood could help a patient. It concerned whether an appropriate supply could be available at the moment of need.
Robertson’s published observations concerned a small group of patients. They cannot be converted into an exact number of lives saved by assuming what would have happened without treatment. The historical significance is substantial without that unsupported calculation. Nor should procedures from a century-old wartime account be treated as present-day medical instructions.
The Supporting Workforce Crossed Continents
The National Army Museum’s collection includes portraits associated with the Chinese Labour Corps in France around 1918. Its catalogue explains that Britain recruited labour from China when skilled and unskilled workers were urgently needed. Their duties were non-combatant, but work in threatened rear areas and on communications routes was not free from danger. [16]
This widens the meaning of the team. A research organisation can help develop useful equipment while people far from its laboratories perform the work required to move, maintain and support the wider war effort. An account restricted to the most celebrated scientists gives an incomplete picture of the capacity being assembled.
It also prevents a national label from becoming a claim that all the work was supplied by the nation appearing on the organisation’s name. People crossed borders under different contracts and conditions. Their contribution deserves recognition without assuming that all participants had equal authority or experienced the undertaking in the same way.
The collection records particular people and a particular organisation; it does not provide a complete account of all Chinese wartime labour. Here, it establishes the essential point that the human infrastructure of the war extended well beyond European factories and battlefields.
10 August 1915: A Research Career Ended at Gallipoli
We return to 1915 to consider a different effect on knowledge. Henry Moseley’s work had helped establish the importance of atomic number in understanding the elements. Serving in the Royal Engineers, he was killed at Gallipoli on 10 August, aged twenty-seven. The research he had completed survived him; his opportunity to continue it did not. [17]
A list of wartime discoveries can make the loss difficult to see. The useful invention has a name and a date. The work a dead person might have undertaken does not appear in the archive as a completed result. It cannot be counted in the same straightforward way.
That does not permit us to assign Moseley an imaginary later discovery or an award he never received. His known achievement demonstrates existing ability; it does not reveal the exact contents of an unrealised future.
Nor is a famous scientist’s death the only loss that matters. People without recognised research careers also possessed relationships, experience and futures. The case makes intellectual interruption visible; it does not establish a ranking in which other deaths become less consequential because no textbook records the victims’ work.
6 February 1918: An Appeal to Stop the Chemical Escalation
On 6 February 1918, the International Committee of the Red Cross appealed for the belligerents to abandon poisonous gases through an agreement. The organisation was intervening not only in the treatment of victims but in the choice of methods producing them. Chemical warfare had become an expanding problem rather than the promised shortcut to peace. [18]
The responses exposed a difficulty. The Entente powers expressed support for an agreement while assigning responsibility to their opponents and making cessation conditional on reciprocal action. An expressed wish to stop did not become a general halt during the war. [18]
Protection and restraint were different tasks. Better protective equipment could reduce some injuries without removing the means of attack. A government might continue harmful activity because it feared stopping first, even while agreeing that universal restraint would be preferable.
This was not a problem chemistry could solve by itself. Scientists could investigate materials and effects. Reaching and enforcing an agreement required political action. The existence of technical expertise enlarged the available means; it did not supply a collective decision about their acceptable use.
11 May 1918: An Emergency Organisation Was Given a Future
Wilson’s Executive Order 2859 requested the continuation of the National Research Council. Its remit linked research in mathematics and the natural sciences with engineering, agriculture, medicine, defence and public welfare. The order sought cooperation among researchers and government services while explicitly preserving encouragement for individual initiative. [19]
The date matters: the war had not yet ended. Officials were already considering how an organisation created for preparedness and military problems might continue to serve beyond the immediate emergency. A postwar inheritance was being shaped before an armistice made demobilisation the urgent question.
The order did not guarantee discoveries or an uninterrupted stream of funding. It established duties and a relationship with the National Academy. Staff, resources and workable cooperation still had to sustain the undertaking.
Its emphasis on individual initiative also identifies a tension within coordination. Bringing people together can prevent unnecessary duplication and connect useful skills. Requiring every investigator to follow an identical plan can close off questions that nobody at the centre anticipated. Organisation has to enable inquiry without assuming that all valuable answers can be ordered in advance.
11 November 1918: The Immediate Task Changed Again
The armistice between Germany and the Allies took effect on the Western Front at eleven in the morning on 11 November 1918. It stopped that fighting; it was not a complete peace settlement or the end of violence everywhere. The National WWI Museum’s account preserves that distinction alongside the relief recorded by people receiving the news. [20]
For the organisations followed here, the end of hostilities created another problem of purpose. A hospital still had patients. A research group might have unfinished work. A factory’s future depended on what would be ordered and who would continue paying for production.
A wartime arrangement could not simply be judged by whether it remained unchanged. Some functions should end when their emergency purpose ended. Others might be adapted for civilian needs. The task was to decide what to preserve, what to dismantle and how to make those changes without abandoning the people affected.
That is the immediate aftermath the next chapter will examine. It belongs between the armistice and the later political catastrophe. Neither a useful laboratory nor the anger of a defeated country had a single, predetermined path from 1918 to 1933.
What the First World War Adds to Our Original Thesis
The evidence changes the comparison between America and Germany in a necessary way. Both could organise substantial expertise, and neither did so in isolation from earlier education, industry and international knowledge. Germany’s later persecution destroyed opportunities within a highly developed scientific society. America’s later mobilisation drew on earlier experience but still required new institutions and decisions.
There was also more than one way to mobilise a mind. A chemist could be assigned to military research, an organiser could collect information about national supplies, and a physician could redesign the relationship between a donor and a patient. These were different contributions to capacity, with different responsibilities and consequences.
The strongest causal account follows the connections: preparation made expertise available; appointments and assignments determined where it went; resources and supporting labour made it usable; political authority decided many of its purposes. Failure at one connection could leave the others insufficient. The hospital without a room and the programme whose plants arrived too late make that limitation concrete.
This chapter has not calculated which research programme contributed the largest share to victory. Nor has it shown that expanding military production necessarily increased overall welfare. A system could become better at meeting wartime demands while consuming resources, exhausting workers and destroying people whose future work would never be recovered.
Those losses cannot be removed from the argument by pointing to a later benefit. Improved care is valuable because people need care; it is not evidence that the injuries were an acceptable way to obtain the improvement. Historical influence and moral justification remain different questions.
The Room After the War
In the opening letter, Curie was waiting for the hospital to make a place for useful work. In her later book, she argued that the radiological organisation developed during the war should support wider civilian care rather than disappear with the emergency. That was an argument about what should follow, not proof that everyone immediately received the proposed service. [7]
The two moments belong together. First, someone had to connect an existing discovery with an urgent need. Afterwards, someone had to decide whether the organisation built for that need would survive in a different form.
The prequel has now followed the creation of research communities, the connection between science and factories, the international relationships supporting them, and their redirection during war. Prequel Part 6 opens with the armistice’s unequal provisions for returning prisoners, then follows food supplies, Versailles, Germany’s new republic, the League of Nations and research support. It asks how a decision on paper became—or failed to become—a journey home, a livelihood or an institution able to continue its work.
Mobilising knowledge could enlarge what a country was able to do. It could not decide whether the purpose was just, protect every person doing the work, or guarantee that the capacity would survive the war that had called it into service.
