Paul Régis Hauser (27 February 1947 – 23 April 2009) was a French writer and puzzle designer, famous as the creator of numerous treasure hunts, including On the Trail of the Golden Owl, under the pseudonym Max Valentin.
[3][2] Hauser wrote books about his professional activities in communications, as well as about popular subjects, such as remarks on women,[4] and funny or unusual graffiti.
From 1993 to 2001, Hauser created many treasure hunts, in print and online, often under the pseudonym "Max Valentin".
All his treasure hunts were solved or halted by their producers/publishers during his lifetime, with the exception of On The Trail Of The Golden Owl.
[10] Players hide treasures somewhere in France, and then create riddles that conceal the location.
