Sorry for the late reply, I’ve been too busy the last few months… This man is a well-known figure in Dutch Martial Arts and played a role in the “pioneering” days of Martial Arts in this country. He is also well known for his fantastic stories, ultra bold claims, giving away of Dan certificates and strange stunts (he once bulldozered the office of a newspaper that wrote negatively about him).
It bugs me that this man got an entry on Wikipedia. I should really drop a message on the discussion page. He even got his “biography” published that was written by a dopesmoking reggae DJ. I have the book but haven’t read it yet, it seems well written but besides that is just another (and apparently) successful) attempt for Prince Dschero Khan AKA Gerard Karel Meijers to spawn his propaganda. Many of the claims in the book about monks in Asia, a monastery in Indonesia, military background in Indonesia, etc are probably hard to refute. So much time has passed and, personally, I don’t know any Indonesian. This is what I do know:
As for his martial arts mastery: he trained in Kuntao (kung fu that came to the Netherlands by Indonesia), ju jutsu/judo and Karate. He never achieved a black belt in the Japanese arts (at that time there was only one MA organization over here, so this is a fact) and later awarded himself a black belt in Kempo (a term used to designate Kuntao). His tenth degree is from master Huang Sian Teh from Taiwan. His organisation is called the World Chinese Martial Arts Federation. The MA orgs in Taiwan are, from what I heard, quite lenient in the styles they acknowledge. Apparently they acknowledge kempo/kuntao. Both the master and his organisation seem legit. See wikipedia: http://en.wikipedia.org/wiki/World_Chinese_Martial_Arts_Federation
You can find a pic of his 12th degree certificate and pics of him teaching in Taiwan on this site:
I strongly doubt if the ever did any examination for this org.
His military claims. The only thing I have to refute his claims is his military number that contains his date of birth, which makes him 7 years younger. He couldn’t fight in the KNIL if the was only 10 years old. He has served in the Korean war and in no other war. He has not a single award for bravery. (from an old dutch newspaper article).
Now for his claim to be a descendant of Djengiz Khan. Djengiz Khan apparently slept with 200 to 300 women (this is legend, but might contain a grain of truth), so there should be quite a few descendants running around in Asia. It must be said: he DID get an audience with the government of Mongolia. The embassy of Mongolia said: “there is no royal family of Mongolia, there hasn’t been since 1924”.
Does this make him a total fraud? It’s just how you look at it. He was, from what I have been told, a proficient martial artist and a good teacher (these were the pre-UFC pre-Muay Thai days). He has some good students still active.
Feel free to post any questions about this may if you have any. I have quite a bit of material about him at home.
