The ever developing Harry Lembourn story

I first became aware of the existence of the Lembourn story late 2014 when I copied a multi-volume scrap-book with clippings from Danish newspapers and mainly from Nationaltidende.

From “Nationaltidende”s coverage of the Lembourn case and his contacts with the French assistant military attaché Captain Sorne. This photo in the paper on 11 January 1929 shows Danish and French officers enjoying an informal lunch somewhere in Denmark. Could be in Tondern Garrison. Harry Lembourn marked by cross.

Thereafter I started a full scale research into the case. After having read the massive Danish War Office personnel case file on Captain Lembourn, the biased Danish Foreign Office and Danish Berlin Legation case files as well as the contemporary press coverage in both other Danish and German newspapers, I became ever more aware that the decisions of Danish authorities were neither straightforward nor fair. And I was left in no doubt about the pain the events and Danish reactions caused the family. What really made me keenly aware of the family’s both pain, anger and loyalty was Thordis Lembourn’s search in vain for fairness and justice in a mid-1930s letter to the Danish Prime Minister Stauning.

The files highlighted the degree of miscarriage of justice inflicted on Lembourn by panicky Danish authorities eager to appease the rearming Germany in a sacrifice of not only this awkward “spy”, but also the destructive effects on the ad hoc defence of the returned province of South Jutland that Captain Lembourn had been so imprudently active in supporting.

Background of events and what I now know or must conclude happened:

(I have to emphasise that most of the book I now write, is describing the development and workings of the Danish Armed Forces activities in the 1920sas a not formal, but by Germany suspected de facto ally of France. The narrative will have a special emphasis on the creation of the South Jutland defence plan and forces and consideration of direct naval co-operation in the Baltic Sea)

The general background and framework of Lembourn’s case was the following: Within six weeks after the end of fighting on 11 November 1918, Copenhagen had become the main base for Entente forces’ (mainly Royal Navy) intervention in the present Baltic States to push the Germans out and help defending against the Reds.

By 1920 this objective had been achieved, and even if Copenhagen Harbour remained important for the Western Powers, it was now mainly related to French support to Poland in its war against Soviet Russia. By spring-summer 1920 the Allied guaranteed plebiscites in North Schleswig led to the return of South Jutland to Denmark, and the new Liberal Government from May onwards was especially grateful towards France for her clear, but ineffective, support for Denmark keeping control of the city of Flensburg.

The new Danish Defence Laws of 1922 with deep budget reductions became built on the premise and strategy of a de facto alliance framework based on the collective security obligations of the League of Nations. The potential enemies of the tacit alliance were the non-League-members Germany and Soviet Russia, and all defence planning and exercises the next years were based on direct Danish military and naval cooperation with Britain and France.

The fluent French speaker Harry Lembourn benefited directly by spending the next couple of years on detachment to the French Army.

During his time as a young regimental subaltern during the war, Lembourn had played the active batchelor officer and gentleman, using his quarters at his 22nd Infantry Battalion barracks at the Copenhagen Citadel as his base. During 1917 and 1918, when he had become the battalion adjudant, he had much time in town, where he improved his dancing skills at the Tango, which had reached the Danish Capital from Paris just before the war. However, now in his mid thirties and approaching promotion to captain, Lembourn must have decided it was time for a change. In April 1923, during his last year in France, he met the 19 years old Norwegian girl Thordis Svane during his Easter holidays in Nice. They got married 16 months later in Tondern.

During his two years on exchange training in France, Lembourn served the first year from November 1921 with the 158th Infantry Regiment in Strasbourg. He was then authorised to follow the last 8 months of the second year of the course of L’École spéciale militarie de St Cyr, the famous French Military Academy, followed by September and October 1923 with a tank regiment before returning to Denmark.

A few moths after his return to Denmark Lembourn joined 2nd Infantry Battalion on 1 April 1924 in the new Danish Army Garrison in the South-Western Jutland town of Tondern (Tønder). On 18 August he married Thordis.

With its large German population group, the town remained very much on the frontline between Danish and German. At the 1920 winter referendum, 77 percent of Tondern’s population had voted for Germany. In the struggle against German influence, Lembourn, who was always eager and working hard to please his peers, became active on two fronts. Firstly he became the leading promoter of French language and culture as head of the local Alliance Française, and secondly he offered his service as weapons instructor for the new volunteer defence organisation Jydske Værn (the Jutland Guard). The latter was natural to him as he had previously worked in Copenhagen instructing the likewise volunteer Kongens Livjægerkorps (The Royal Life Rifle Corps), which had its depot at the Citadel, his battalion barrachs. The Chairman of the Board of sponsors, etc., of Jydske Værn was the veteran leader of the Danish county and city community, Bank Director R.P. Rossen.

Denmark had no standing army, only a training-mobilisation force, and the fact that nationalist militias just south of the border openly prepared to retake most or all of North Schleswig made it self-evident to both the War Office and the local Danish leaders that something had to be done to make certain that a German local militia coup would meet some Danish resistance. Such a coup made by volunteer militia might not trigger an effective League of Nations reaction as surely as a regular invasion.

One pool of locally available trained manpower for defence against such a coup was Danes that had served in the Prussian Army during the Great War. To employ these veterans the War Office authorised the establishment of a Sønderjysk Landstorm (South Jutland Militia) on the basis on mobilised veterans of whom 60-70 % were considered pro-Danish. The only other potential defence force was the small volunteer corps that Lembourn helped training.

The other officer is his 2nd Infantry Battalion and Tondern Garrison commander, Lieutenant Colonel Obel in the old French style grey uniform. Obel later tried to defend Lembourn by giving (accurate) evidence on Lembourns personality, but soon had to stop trying as being vulnerable himself to accusations.

The driving force of the “Guard” that Lembourn instructed in weekends was the far right-wing political activist, Captain Max Arildskov, who had served in the Danish volunteer company in the Baltic Wars of Independence in 1919, but the formal leader of the volunteer guard project was the strong personality, Bank Director R.P. Rossen.

Events in 1928
Lembourn’s attitude profile matched that of a normal Danish regular officer of the period: uncritically National Conservative, anti-German, anti-Socialist, but otherwise with no interest in political issues … or in anything else beyond being considered to be a good army officer and a gentleman. This profile of Lembourn is not only clear from all Danish sources, it was repeated by Ernst Friedrich, Lembourn’s intellectual prison friend in Gollnow Fortress in 1930-31. When reading the Lembourn correspondence, it is it his honorable – but naïve – trustfulness that stands out, including and especially during his fact-finding visit to Berlin in late spring 1928. He was not a man with a strong, independent mind. He just worked hard and loyally to do what his respected peers wanted done.

I have now come to the firm conclusion that when Harry Lembourn choose to speak rather than trying to protect his contacts by silence, he spoke and wrote the truth, because he was incapable of doing otherwise.

According to Lembourn it was the strong willed Rossen that convinced him to make a short visit to Berlin seek information about German nationalist militias such as the large Stahlhelm that openly challenged Danish control of “North Schleswig”. This information was confirmed by the German press after Lembourn’s arrest when it wrote that Jydske Værn had been noted to seek information from Germany for some time.

Lembourn knew Rossen both as chairman of the board of Jydske Værn and as the long-serving local leading agent (“tillidsmand”) of the Tondern part of the Danish General Staff intelligence network, an understanding which was probably still true even if the Bank Director was now also working for the French. However, what is clear is that even if Lembourn later recognized that his report ended up with French Intelligence via the Military Attaché, Captain Sorne (which he seems to have seen as natural – he was later shown his report during his visit to Paris in spring 1933), he assumed that Rossen had sent him to Berlin to organize fact-finding for Denmark about the threat from the large German paramilitary militias, and especially the very large Stahlhelm organisation.

Harry Lembourn had only very limited confidence in himself, and therefore always sought guidance from those formally in command or strong personalities around him to be able to live up to their expectations. Thus he was very easy to manipulate and control.

During the later interrogation by German authorities Lembourn learned that Sorne’s activities and organisation had been monitored by German counter-intelligence from the start.

The local leader of the Danish General Staff Intelligence and French Intelligence representative in Tondern, the veteran Danish community leader Bank Director Rasmus Peter Rossen, who convinced Lembourn to make the recruiting visit i April 1928. (Photo probably from around 1920: Dansk Centralbibliotek for Sydslesvig, Flensborg)

Rossen probably deliberately gave Lembourn the false impression that he would be working direct for Denmark. At the same time Rossen deliberately blocked Lembourn’s idea to contact the Danish Intelligence head, Captain Hother Styrmer, himself as that would make clear that Danish Intelligence had not officially authorised the trip. Rossen told Lembourn that Styrmer knew of the trip and wanted him to make it, so there was no need for a direct contact. This later made it possible for Styrmer to deny any knowledge of Lembourn and his activities.

Lembourn’s fateful two weeks visit to Berlin from late April 1928 to mid-May was conducted in the direct and unsophisticated amateurish way that mirrored both his trustful personality and the extremely short time available. In a local cinema Lembourn (pretending to be the English leather tradesman Mr. Brown from Copenhagen) befriended the local typist Ms Stegelmann. After the cinema followed a drink in a beer-restaurant, and Lembourn convinced her that she should seek information about the German armed forces. The recruitment of such an source of information was the purpose of the trip to Berlin. Contact was established to Denmark and she was sent a list of questions from Sorne going far beyond Lembourns missions. The agreed funds were cabled, probably cabled by Rossen.The sum (500 DKK) paid her and any assistants and covered expenses for buying a camera and a type-writer. The sum equals 2,000-2,500 UK£ today. Rossen might have got the money from the French.

The typist hired an assistant (Mr. Riek) to get the information for the list of questions about possible German violations of the Versailles Treaty. He did so by openly entering the Reichministerium (The National Defence Ministry in Berlin) to seek answers to the questions. The ministry security authorities got suspicious, replied with false information and involved the police. Policemen followed Riek back to Ms. Stegelmann, a convicted criminal, and soon identified Mr. Brown as Harry Lembourn. In spite of Lembourn’s fact-finding “espionage” being uncovered by the police during the Berlin visit, he reached home before being apprehended.

Lembourn noticed later that these German militias that he saw as his main task were not only seen as a menace to South Denmark; the new German Defence Minister considered them a threat to the German State. The open way all happened supports Lembourn’s constant later statements that he did not see his action as anything but legitimate “fact-finding”. It surprised him that it was considered to be espionage. He had not been alert to the content of the questionnaire from Sorne.

The report developed for Rossen was passed-on, and Lembourn had second hand information (but no confirmation) that it had been read by the head of Danish General Staff Intelligence before it ended-up with Capitain Sorne. Sorne was a logical recipient. By 1928 it was clear to all, including the French Intelligence, that Germany had become active in breaking the arms control limitations of the Versailles Peace Treaty after the formal control organization had been disbanded after Germany became a League of Nation Member.

When Lembourn arrived back in Tondern mid-May from Berlin, the 70 years old Bank Director was ill, on 15 June he died, and on 20 June Harry and Thordis crossed the Border for a tourist trip to the North-Frisian Island of Sylt together with other officer families from the Tondern Garrison.

What Lembourn presented as a legitimate and innocent find-finding for Denmark guided by list of questions that he must have been given by Rossen (from the French) could be seen as a clumsy attempt of recruiting foreign agents to seek sensitive information about Germany, and the visit could not have been made at a worse time. In January 1928 the so-called Lohmann scandal about a secret armament program led first of the replacement of the Reich Defence Minister Otto Gessler. On 30 September that year it was followed by the dismissal of the Reichmarine Chief, Admiral Hans Zenker. It was at a time when the Germans had not yet decided what to do with the arrested hapless amateur spy recruiter Lembourn. The character of his effort were apptly outlined by the Berlin paper 8-Uhr-Abendblatt headline (“Eight O’clock Evening Paper”) on 28. June: Solch eine plumpen Spion hat es wohl nie gegeben (“Never before such a clumsy spy”).

During the investigation in mid-January 1929 of Lembourn’s claim that he had acted on behalf of the General Staff Intelligence Section that claim was rejected as incorrect as was the specific claim that the section operated a post-box together with the French Assistant Military Attaché in Copenhagen. The denial of knowledge of Lembourn’s mission was easy as it was standard and sound procedure that only the recruiting leading border zone agent (here the now deceased Rossen) was supposed to know the identity of the agent. For reasons of security (and probably also deniability when something went wrong as here) there was no reason why the General Staff should know the identities of agents not tasked and financed directly be its intelligence section.

Captain Hother Styrmer, the head of the General Staff Intelligence Section, who needed information for his ongoing comprehensive analysis of the threat from the German paramilitary militias. During the winter 1929 investigation of Lembourn’s allegations of working for Danish Intelligence neither he or his superiors found reason to explain how the service was organised and worked with decentralised responsibility for border zone operations. When he had been made aware of the use of Lembourn in May 1928, he wrote to Colonél Burin des Roziers to warn against any further involvement of the captain. That letter was later shown to Lembourn during his spring 1933 visit to Paris to seek French support.

Late January 2018 I have found convincing evidence in the surviving intelligence files of the Danish State Archives that Styrmer actually had pre-knowledge of Rossen’s initiative, even if he may not have known Lembourn’s name before he was sent: On 17 May 1929 Styrmer completed a comprehensive analysis of the German militias with a focus on the Stahlhelm-organisation. It was the military intelligence section’s key analytic work of the year, and its text make clear that its main source foundation was information collected in spring 1918.

Thus Lembourn was probably correct when he never accepted that he only worked for France. But he did understand that his report was shared with the French, which he must have seen as natural considering both the security and defence policy since the war and his own service experience.

The Bank Director’s contact with French Military Intelligence might either have been direct – with Capitaine Sorne or his boss Colonel Burin de Roziers in Brussels – or via the Danish Captain Daniel Bruun. Bruun, a former Foreign Legionaire, seems to have been responsible for a French intelligence network in North Schleswig after the Great War, and Rossen had been on his contacts list as early as 1912. If this theory is right, the trusting Lembourn (he was consider as törich (simple-minded) by the Germans) was sent to Berlin by Rossen to recruit an agent and with the incurred costs paid by French money via Rossen, but still believing that he worked directly for Denmark. If so, it would not be the last time an agent would be cheated into working for a different state than he believed. That theory would explain why the French paid Lembourn a lifelong pension.

The intervew with Capitaine Sorne in Berlingske Tidende,s on 11 January 1929. He had served as the local Copenhagen assistant of the French Military Attaché for more than two years. He underlined in the interview that his mouth was closed: he acted under orders, but he had nothing to hide, being only a small piece of the game.

Lembourn’s arrest was most probably the result of information from hostile German citizens of Tondern and not the German central counter-intelligence authorities based on his activities in Berlin. The arresting Flensburg policeman was known to be anti-Danish.

Nothing much happened during the first months after his arrest – probably because his efforts had been so amateurish – and there were rumours that he would be released, even if it was clear to the Germans that Lembourn had been tasked by France. Then, in late autumn, however, it became clear that the German authorities would use the case against Lembourn to emphasize it as part of the unacceptable Danish defence cooperation with Germany main great power enemy, France.

From the year before the events: Harry’s parents’ – Poul and Maria’s – Golden Wedding Anniversary on 2 October 1927 celebrated at Nyråd east of Vordingborg. The celebration took part in the house of his son-in-law, “Bryggerhuset”, on Nyråd Hovedgade 90 (Photo: From Christian Lembourn and his father’s collection).

Just prior to the court proceedings started, German intelligence received (formally incorrect) information that Denmark was close to joining the (in reality non-existing) French-Polish Military Alliance against Germany. Rumours of the de facto Danish-French intelligence co-operation seem to have been picked up or simply suspected by the Germans. The alleged key Danish contribution would be the full subordination of Danish Intelligence to the French. This false information was most likely what triggered a trial meant to send a clear warning to Denmark to drop any cooperation against Germany.

Throughout the court proceedings the Germans also acted and ruled on the false information collected through their investigation that Lembourn had served in the French Army during the war.

The Berliner Morgenpost found on the day after the Leipzig Court ruling that it was not only extraordinary hard. It would make the misled spies tragic heroes. The latter certainly did not happen to Lembourn.

On receiving information about Lembourn’s sentence (and weeded information from the court proceedings) the Danish authorities started a witch-hunt in vain for any contacts that Lembourn might have had in the central authorities in Copenhagen. As Rossen had died, Lembourn’s role for him remained unknown.

The inherently provocative act of basing a defence of South Jutland on anti-German motives was quickly addressed by first the dissolution of the planned mobilization and use of units of Danish minded veterans and soon followed by pressure to dissolve Max Arildskov’s “Jutland Guard”.

However, the most important signal of understanding of the German warning was the total destruction of the future of Lembourn to discourage others. However the “Generalauditør” Victor Pürschel (the chief legal advisor and official of the Defence Minister) made absolutely clear in 1929 and later that a 1888 Supreme Court ruling against the Government (the Finance Ministry) in a similar case blocked the legal option of removing Lembourn’s salary and later pension. Then the retired Danish Captain Christian Sarauw, who had had a key role developing French intelligence against Germany, had claimed his pension after returning to Denmark after serving two years of his twelve years penitentiary sentence. Both the Intermediate and Supreme Courts had ruled clearly in Sarauws favour that no foreign court ruling could be used as basis for the Danish administrative decision such as removing an officer’s pension.

At the time of Lembourn’s sentence, Pürschel had just lost the position of leader of the Conservative Party group in the Lower House of Parliament (Folketinget). Both he and his post-Second World War successor as the chief legal officer of the Defence Forces kept underlining that depriving Lembourn of his pension was illegal.

The Danish Minister Herluf Zahle. He did his best from the arrest to undermine Harry Lembourn’s position and have him punished in Denmark as severely as possible as a human sacrifice to appease his German hosts.

The warning implied by the Lembourn arrest war clearly received even before the start of the trial. The Danish Minister in Berlin, Herluf Zahle, begged the German authorities that it would be closed to the public not to harm Danish-German relations too much. Zahle had always been a strong believer in a complete and unquestioned proactive subordination of Denmark to German security interests. From Lembourn’s arrest he never doubted that the Germans were right and worked hard to have Lembourn sacrificed to underline his country’s full and unquestioning subordination to German interests and power. During the war he had been the Foreign Affairs Minister, Erik Scavenius’, trusted assistant in negotiations meant to ensure a smooth and bloodless transfer of part of Denmark to German occupation if that had been considered necessary by the German Navy. From Lembourn’ sentence on 9 January Herluf Zahle had made clear that Denmark would do nothing to have the extremely harsh sentence of 5 years penitentiary reduced. He would only do so when the German Foreign Ministry explicitly asked him to do so on 21 February, and thereafter he would work to seek proof of Lembourn’s guilt. The legal approach closed, the Government used the 1929 supplementary state budget to remove Lembourn’s pension and thus proving to Germany that Denmark had got the message. The decision was justified by the claim that by working for French Intelligence Lembourn had violated the requirements of his employment contract.

Where the German Court prosecutor had accepted that Lembourn had acted from ideological motives, the Danish authorities rejected that notion and ruled that the money send by France to pay for expenses in Berlin was pay so that Lembourn acted out of greed and thus dishonourably.

During the next 25 years bureaucratic stonewalling succeeded in blocking repeated Lembourn family and legal supporters’ attempts to question the spring 1929 decision.

No wonder that Harry, his wife and later generations of the family found and find it difficult to understand what happened then and later; namely:

1) How Lembourn could believe that he worked for the Danish General Staff Intelligence and the Danish Intelligence leader could claim without lying that it had no positive knowledge of any such affiliation. That would always be the situation as all border agents were recruited and controlled locally until 1937.
2) That Germany had given Denmark a clear warning by giving the hapless Lembourn an initially brutally hard prison sentence for his amateur attempt to set-up spying against violations of the Versailles Treaty that had already openly acknowledged and accepted of the German and international press.
3) That Denmark found it necessary to send the message that she had learnt by firing Harry Lembourn, removing his pension and continuing a campaign to destroy him, ignoring normal rules of law in a Kafka-like regime to uphold the effects during the following years. The officials even rejected to revisit the decision after the German defeat in 1945 (probably because the same civil servants were still in key positions).

Even in April 1946 the War Minister rejected Lembourn’s request to see the text of his 1929 sentence, because Denmark had promised Germany in 1929 not to do so. (Document from the Øhlenschlæger family collection, inherited from Harry’s youngest sister, “Alix” (Alice))

The trusting and always loyal Lembourn walked blindly into a mine-field that he still failed to see as such even after it had exploded in his face. He gave the Germans the chance to use him as an effective warning against Denmark and his own country an easy and way of proving that it surrendered. His family lost its home: the married quarters flat in the Tondern Barracks. His captain’s norm and position as company commander in the Tondern Garrison was immediately occupied by the promotion of Erik Jonstad-Møller, who as Major-General was to become the first commander of the new Danish volunteer Home Guard in 1948, where Lembourn sought – but failed to be allowed – a position.

The anti-military, anarchist, German trouble-maker Ernst Friedrich would use much of his late 1931 book on his time in Gollnow Fortress Prison in Pomerania in a vain attempt to support his Danish military gentleman friend’s case. Here their last beer together. Lembourn as always dressed as elegantly as possible, and even the anarchist in suit.

The most important pieces I used to miss to tell the Harry Lembourn part of the book’s story in a proper way, were family photos from 1919 to Harry’s death, and especially a photo of Thordis from around 1930. The family deserved it after the miscarriage of fairness and justice that you – mainly Harry, Thordis and the two children – have suffered. The more I read and understood, the angrier I have become and the more eager I am to get the story out. The family has now responded, and the grandson Stuart Fry in Australia has sent me some key photos.

The Danish reaction to the Lembourn affair was the start of what ended on 9 April 1940. Zahle, the Danish Berlin Minister was still in the same position twelve years later.

I hope to be able to publish the book early 2019 at the University Press of Southern Jutland in Odense that I normally work with. If the family accepts, the book shall be dedicated to it.

The earlier somewhat similar case of Oluf Wolf:
Wolf had crossed the border from North Schleswig in 1915, and a year later he was recruited by a Dane working for French Intelligence by debriefing deserters and others who arrived from Germany to the Kolding district in Denmark. Those with important information were sent to Copenhagen for further debriefing by the French Military Attaché. He proved to be a very effective agent and focused successfully on collecting intelligence on the Imperial German Navy’s activities in the Baltic Sea and Little Belt. What he collected was also passed-on to the Danish Army Intelligence via its agent in Kolding.

Harry Lembourn’s effective and more lucky predecessor Oluf Wolf, here in the 1930s (Photo in family possession)

Wolf’s and other Entente intelligence activity north of the border were exposed in early 1918 when German Counter Intelligence succeeded in infiltrating a double agent posing as a deserter. All were arrested by the Danish Security Police and interrogated, revealing what happened. The Danish Intelligence Chief denied any knowledge of the source of the information he had been sent by his Kolding agent.

All arrested were were soon released with a warning which the German Minister had to accept to avoid the exposure of his double agent and all the negative reaction to be expected from the anti-German Danish public opinion in a court case Danes working for the Entente.

The German Navy did not forgive or forget the damage done by Wolf’s espionage, and some weeks after he had returned to his farm south of Haderslev in the still German North Schleswig, he was arrested and sent to the Moabit prison in Berlin to await trial for war-time espionage work for an enemy state at the Leipzig Court and then receive his sentence of five to ten years penitentiary. However, after 13½ months Wolf was released, and two years later he was thanked by France be being decorated with the Knight Cross of the Legion of Honour at the country’s Copenhagen legation.

There were many similarities with the Wolf and Lembourn cases. Both worked for both France and Denmark for patriotic reasons. Both were arrested when naïvely going to Germany and thereafter soon sent for investigation to Moabit Prison in Berlin. In both cases Danish Intelligence denied any cooperation with France and any knowledge of the arrested person and his activities.

The main differences were 1) that Wolf’s espionage activities had taken place from Denmark, where Lembourn’s had taken place in Berlin, and 2) that Wolf’s very effective work had really damaged Germany where Lembourn’s amateurish efforts never achieved anything.

The real important differences, however, were in the reactions of the two involved states’ authorities:

* In Wolf’s case the Danish authorities and public opinion felt supported by Allies and made every effort to get the effective spy home. He was given highly qualified legal assistance and full support of the Danish Berlin Minister. Germany was weak and wanted to case to go away.
* In Lembourn’s case the Danish authorities and public opinion wanted to please and appease the authorities of the emerging German power. The Germans should punish the bungling spy as hard as possible, and Denmark would reinforce whatever they did. He was deprived of the chance of getting qualified legal assistance and his country did everything possible to reinforce the case against him.

The story has developed thanks to the assistance of my young historian colleague Dr Kristian Bruhn, who made his growing understanding of the contemporary Danish Intelligence community available.

Siegfried Matlok, the respected veteran leader of the German minority community and former chief editor of “Der Nordschleswiger” found many additional contemporary articles dealing with the “Lembourn Case” in the local newspapers. He made it possible to create a consistent narrative of Lembourn’s actions during his “fact-finding” trip to Berlin late spring 1928.

Different members of the extended and direct family found and supplied copies of documents and photos. First Viggo and Niels Øhlenschlæger and then Christian Lembourn from Danish parts of the extended family. Via Niels Øhlenschlæger and his English relatives, I was contacted by Stuart Fry, Thordis and Harry Lembourn’s grandson, who lives outside Melbourne in Australia.
