Jan was born in Tilburg in The Netherlands in 1947. Ever since he was a little boy he has been interested in puzzling problems. This enthusiasm has never let go. The interest has developed and for the past few years he has concentrated on archiving the posted puzzles in the news group alt.brain.teasers and developing puzzles. He loves reading, collecting books and puzzles, and basically having a lot of fun.
