Today’s Gutenberg Gem is Edward Lasker, a rather colorful individual in the history of chess. He won the championship of Paris in 1912, in London in 1914, the New York City championship in 1915 and the Chicago championship in 1916, and then went on to become an International Master at the age of 75. He also wrote one of the first English language texts on Go. He should not be confused with his cousin, Emanuel Lasker, who was world chess champion from 1894-1921, and he liked to play Go too.
