My name is Claus, born in 1963 at Eschweiler on the River Inde and now living with my wife in Köln. Pronounce my first name like "clouds" without "d"!

I am a teacher for mathematics, physics and business informatics at the NBBK in Haus Rheinfrieden, a commercial college for physically disabled persons. My secondary school was the Städtische Gymnasium Eschweiler, a municipal gymnasium, and I studied first mathematics and then teaching at secondary schools at RWTH Aachen University and the University of Paderborn. All these places are situated in North Rhine-Westphalia in Germany in the European Union. My mother tongue is Eischwiele Platt, a Ripuarian dialect. --CJKG (talk) 08:47, 2 March 2014 (UTC)
