What do you think Eugen Nielsen did when the Nazis occupied Norway?
Eugen Nielsen assisted the German security police in all matters pertaining to the Norwegian Freemasons. Starting in the summer of 1940, he was tasked with managing the Freemasons’ assets. He prevented parts of the Freemasons’ assets from being sent to Germany, but in the autumn of 1941, large portions of the Masonic library of 5,400 titles were nevertheless sent to the German security police headquarters in Berlin. Here, the literature was catalogued and studied by scientists - Gegnerforscher - who were to map what the Nazi’s main enemies stood for. In the beginning of the war, studies were made and theses written about what the Freemasons stood for; exhibitions were produced which showed the Freemasons’ secrets and the propaganda against this group was intensified. Later during the war, this research was discontinued as there was more need of the men who worked on this as soldiers.
Parts of the Norwegian Masonic library is still to be found abroad; among other places in the National Library of the Czech Republic.
After the liberation, large quantities of the Freemasons’ assets were discovered in Eugen Nielsen’s Frogner home in Oslo. He was arrested and convicted of treason. He died in 1963.
