The first world chess champion Wilhelm Steinitz was born on May 14, 1836.

Unbeaten in match play for 32 years from 1862 to 1894, the Austrian was also a writer and theoretician who prominently influenced the development of the game.

"The first essential for an attack is - the will to attack!"

"Steinitz was the first to realize that chess, despite being a complicated game, obeys some common principles. Up to his time, people had just been playing chess, Steinitz began to study it,” Vladimir Kramnik in 2005.
