Johannes Blum Collection


Number of interviews: > 1100

Number of recordings: > 1200

Kazerne Dossin digitised the interviews and converted them to MP4.

The research files consist of both paper and digital documents, which were merged by Kazerne Dossin into a digital file.

Among those interviewed are Jewish camp survivors, Jewish and non-Jewish resistance fighters, political prisoners, hidden children, hidden adults, hostages, refugees, survivors of the Rwandan genocide, Spanish Civil War volunteers, anti-fascists and children of members of these groups of witnesses. Most of the witnesses lived in Belgium during and post-war.


In 1987, Johannes Blum started recording testimonies of Holocaust survivors in Belgium, and from 1993 he made audiovisual recordings. Over the years, he interviewed more than 1,100 people, some of them several times. For each interview, Johannes Blum also compiled a research file, including copies of documents, newspaper clippings, photos of the witness, (scans of) historical photos, written testimonies, publications and obituaries. In 2003, Johannes Blum contacted the Jewish Museum of Deportation and Resistance, the predecessor of Kazerne Dossin. His collection was then transferred to the archives of the JMDR. Kazerne Dossin continues to digitise the recordings and research files.

During the Second World War, millions of people lost their lives in German concentration camps. There were survivors, but they are slowly dying out. Soon there will be no more people who can testify at first hand about the horrors of the camps. Their memories – however horrific – must never disappear.


A book has been published and a documentary made

The five-part documentary by Luckas Vander Taelen records the story of fifteen Flemish Holocaust survivors and imprisoned resistance fighters.

De laatste getuigen is a five-part documentary made in 1991 by Luckas Vander Taelen for VTM. It is a timeless document that has lost nothing of its power even 20 years later. In the series we see how the filmmaker and fourteen Belgian survivors return to the concentration camps where they were held during the Second World War. Seven of them are Jews, the other seven were arrested and deported by the Nazis and their accomplices because of their political convictions and acts of resistance.

Luckas Vander Taelen spoke extensively with these last witnesses of the Nazi horror, first here in Belgium and then during a journey to the camps where they had been imprisoned for months or years during the war. They returned to Dachau, Ravensbrück, Natzweiler, Mauthausen, Buchenwald, Gross-Rosen, Bergen-Belsen, Auschwitz-Birkenau and other places.


They testify about their experiences, from the moment they were picked up, their deportation, arrival and life in the camps, and later their liberation and return to Belgium. The result is one of the most striking and penetrating documents about this terrible period in our country’s history.

During the recording, a fifteenth witness was added: Samuel Hejblum, a Jew, was deported to the Auschwitz-Birkenau camp on 5 August 1942. There he worked for a fortnight in a special commando who was in charge of the first gas chambers. His duties included carrying the bodies to the crematoria. Later, he also had to empty the goods wagons that brought the Jews from all over Europe to Auschwitz and sort out their meagre possessions. This is a unique testimony from one of the few survivors of a Sondercommando.

“Were films made during the war?”, people often ask you when you say that you have been researching Dutch film in the Second World War for years. Yes, you name it, it was made in the Netherlands during that time: feature films, documentaries, propaganda films, animated films, advertising films and youth films.

For his research into The Dutch Film Industry during the Second World War, Egbert Barten interviewed the following people:

H.N.J. Beekman, F.P. van den Berg, Joop van Essen, A.C.J. Holla (2x), mw. Hornecker, Frits Kahlenberg, Jan Koelinga (2x), A.W.H. Kommer, R.J. Meijer (3x), E. van Moerkerken, Th.E. van Putten (2x), Gerard Saan, B.P. Wijnberg (2x).

Dr. E.J.W. Verwey, curator of the RUU, took the initiative to research the Philips commando in the Vught concentration camp after a reunion of people who had been involved. 
Verwey himself had also been in the camp. Via Prof. von der Dunk, student W. Velema was found willing to carry out the research and write a doctoral thesis on the subject.
Braakman, Laman Trip, Peeters and De Wit were interviewed together. At the time, they were involved in the leadership of the Command and thus had to deal with the daily practice of ‘Vught’. A more general discussion is also held with Philips and Rathenau about the Philips group in the period 1940-45. F. Philips, at the time of the interview president of the Board of Directors of NV Philips, was director of the Philips factories in Eindhoven. Rathenau was involved with the Jewish (SOBU) workshop of Philips, among other things. At the time of the interview, he was Professor of Mathematics and Physics at the Municipal University of Amsterdam.

Camp Westerbork in the eastern part of the Netherlands was the last station for more than 100,000 Dutch Jews to be deported to the Nazi death camps. Over 80% of Dutch Jews were deported, the highest percentage in Western Europe. The emotion and tragedy of the story is enhanced by the remarkable photographs and films of Rudolf Breslauer, camp photographer and filmmaker. This is the first documentary film ever made about this Nazi transit camp in the Netherlands, with a large series of interviews with survivors who played an important and prominent role in the camp, such as youth leaders, about the hospital, religious life, entertainment and other elements of life in the camp. Among the interviewees is the non-Jewish Dutchman Adrianus van As, head of the distribution office in Camp Westerbork.

Witnesses of Theresienstadt

With a dozen filmed interviews, this project contributes to the knowledge and image of the Jews deported from the Netherlands and their memories of the German concentration camp Theresienstadt in the present Czech Republic. Theresienstadt was mainly a transit camp for Jews, who were mostly sent to the extermination camps. The interviewees are Jews who were deported from the Netherlands to the camp in 1943 and 1944 and stayed in the camp for short or long periods of time (or even twice) during the last two years of the Second World War. The following questions are central to the interviews: How did the eyewitnesses experience Theresienstadt and which elements played a decisive role in their survival strategies? How did the prisoners cope and what gave them their strength?


The approximately 5000 Jews from the Netherlands in Theresienstadt were a very heterogeneous group. About half of them were German-speaking and as Austrian or German emigrants or refugees they had a completely different history than the Jews born in the Netherlands. There were also several groups of privileged Jews (such as the ‘Barneveld group’ and the ‘Mussert Jews’), while other categories (such as the Jews on the ‘Puttkammer list’) had a much less protected status.


It is often said about the Dutch group that they were conspicuous in Theresienstadt for their unwillingness to work, their maladjustment and their passive resistance. These characteristics, attributed mainly to Dutch prisoners, were mentioned indirectly in the interviews with survivors, but were not automatically confirmed by the respondents.
