Mathias Wüllenweber founded ChessBase back in 1986. His ideas about restructuring chess knowledge with the help of computers and chess databases were groundbreaking. He was the first to develop a digital database with thousands of chess games, nowadays a standard tool for every chess player, at that time a formidable weapon. Many more ideas followed: ChessBase, a chess database program, the chess engine Fritz, playchess.com, the biggest chess server in the world, and last but not least, Ludwig, a program which composes, writes and arranges music for you.

Mathias Feist is also a programmer and one of the brains behind the Fritz engine. Today, improving the engine is more and more difficult, but Mathias is keen on doing just that. He also plays a crucial role in the development of all Chessbase interfaces and thus is the man to ask when it comes to explaining certain software features.
