By the early 20th century, Go had spread throughout the German and Austro-Hungarian empires. In 1905, Edward Lasker learned the game while in Berlin. When he moved to New York, Lasker founded the New York Go Club together with (amongst others) Arthur Smith, who had learned of the game while touring the East and had published the book "The Game of Go" in 1908. Lasker's book "Go and Go-moku" (1934) helped spread the game throughout the US, and in 1935, the American Go Association was formed. Two years later, in 1937, the German Go Association was founded. World War II put a stop to most Go activity, but after the war, Go continued to spread.
