In the 1930s Japanese influence in Asia was expanding and felt threatening for most Western powers in the region. The Dutch with their presence in the Dutch East Indies were part of this fear. The actual extend of the threat would finally become clear with the start of the war against the Japanese from Pearl Harbour onwards.
In these 1930s the Dutch Military Intelligence already worked on breaking the codes the Japanese used for their international communications. What I was not aware of when I wrote my blog about some artifacts from the Krieger collection (read it here: https://erikscollectables.wordpress.com/2017/03/31/the-krieger-collection-tsubas-and-netsuke/ ) is that Dr. Krieger actually was part of this effort!
A collecting friend has several items in his collection that relate to this subject and he brought this fact to my attention. It is even mentioned in the book by Robert Haslach about the subject. The dutch Naval officer Nuboer asked for the help of Krieger (also a former Naval officer!) in his effort in breaking the Japanese codes in 1934. Nuboer would eventually be successful in his efforts! You can read some more about him here http://resources.huygens.knaw.nl/bwn1880-2000/lemmata/bwn4/nuboer
The friend has in his private collection a Naval uniform of Nuboer and a tropical suit that belonged to Krieger. Here some pictures of the Nuboer uniform.
How Nuboer and Krieger came into contact is not yet clear and subject of further research I want to do. What is clear that the help of a former Naval officer with extensive knowledge of the Japanese and their language was valuable to the Dutch Forces.
This was formalized in 1937. Henri Koot, the head of military intelligence requested his official help. Krieger would become, next to his job as Curator of the Asian department of the Leiden Ethnographical Museum, member of the General Staff of the Army in The Hague. His work would only end after the German occupation in 1940. Due to the secrecy of the job and the subsequent war little is known about this period but it will also be subject of further research!
So even a blog that starts out to be about artifacts and their provenance an unknown (to me) military history link appears, synchronicity?
