Life and career
Hauser was a native of Sarreguemines, Moselle. During childhood, Hauser and his brother Jean-Loup were members of a band, 'The Tigers'. They held concerts in France, Belgium, Germany and Luxembourg. Later, in the 1970s, Hauser became a rally driver. He also had a career as a marketing consultant and was a keen adopter of new technologies. This lead into his work designing treasure hunts.

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.
- On The Trail Of The Golden Owl (1993) was Hauser's first treasure hunt. He started to think about it in the late 1970s, and launched it in May 1993. As of 2018, the Golden Owl has not been located, and the hunt is ongoing.
- Cryptique (1996), a series of online treasure hunts commissioned by Microsoft France, for the launch of MSN. Four were published in 1996; the last two in the series were canceled at the last moment.
- Book of Orval Treasury (1997).
- Treasure hunts for Paris-Match (Michel Lafon, 1997).
- Hunting allergens (1998), an internal non-public hunt for pharmaceutical company Schering-Plough.
- The Treasure of Malbrouck (1999), a hunt commissioned by the General Council of Moselle to celebrate the reconstruction and public opening of the Castle of Manderen (former Malbrouck Castle). At the request of the organizers, the riddles were themed around the castle, Malbrouck, and Moselle.
- Venice (2000) for Cryo Networks. Twelve treasure hunts were planned, intended to be released online one after another, as soon as the previous one was resolved. Only the first two were published, as Cryo Networks decided to close the game. The riddles of this hunt, although calibrated to last for two months each, were rather hard to solve.
- The Mystery of the Victoria (2000), commissioned by Junior Science & Vie magazine. The first fifteen young researchers who had given the correct answer to the riddles were invited, with their families, to the castle of Thury, where they were given the opportunity to compete to unearth a chest containing the treasure, hidden in the park.
- Treasure Hunt 2001 (2001), a large online treasure hunt conducted in eight languages. It was launched at 00:01 GMT on 1 January 2001. The developers spent lot of time on design, implementation, graphic development and the interface.
- Goal : Treasure (2003) for PlayJam, a TV show created by the Canal Satellite group.
Hauser was also the creator of the online "Game of the Cistes". Players hide treasures somewhere in France, and then create riddles that conceal the location. Other players online can try to find them.
