Klaus Wilhelm Heinrich Teuber[1] (25 June 1952 – 1 April 2023) was a German board game designer best known as the creator of Catan.

Teuber was inducted into the Origin Awards Hall of Fame by the AAGAD (Academy of Adventure Gaming Arts & Design) in 2004.

[9] Teuber graduated from high school and did military service, then studied chemistry, then completed his intermediate diploma (receiving a degree in chemistry[1]),[9] then joined his father's 65-employee dental laboratory business which fell into large problems, and his father fell ill.[10] "When I had trouble in my former profession and needed a mental vacation, I read a book about witches and decided to make a game that follows the story first.

[15][2] He took four years to develop the island-settling game; his major breakthrough was when he introduced hexagonal tiles instead of using squares to represent wood, ore, brick, wool, and wheat.

[3][8] Catan has been credited with launching a new more "social" era for board games, introducing bargaining and bartering among players as part of the strategy to win.

[3] The family game business was incorporated as Catan GmbH in 2002 and his sons Benjamin and Guido are directors while his wife Claudia and his daughter also have roles as bookkeeper and tester.

Teuber won the award, Spiel des Jahres (Game of the Year), for Barbarossa in 1988,[3] Adel Verpflichtet (Hoity Toity) in 1990, Drunter und Drüber (Wacky Wacky West) in 1991, and Die Siedler von Catan (The Settlers of Catan) in 1995,[2][4] winning the award four times.
