Emanuel Lasker was a German chess player, mathematician, and philosopher. He was the second World Chess Champion, holding the title for 27 years, from 1894 to 1921, the longest reign of any officially recognised World Chess Champion in history. In his prime, Lasker was one of the most dominant champions, and he is still generally regarded as one of the strongest players in history.

The fifth World Chess Championship was held in New York City, Philadelphia, and Montreal, and was contested from 15 March to 26 May 1894. Holder William Steinitz lost his title to challenger Emanuel Lasker, who was 32 years his junior.
