Hon'inbō Shūho

Hon'inbō Shūho (本因坊 秀甫; 1838 – October 14, 1886), born as Murase Shūho (村瀬 秀甫), was a professional Japanese Go player who was an important figure in the popularization of the game. He was the first Japanese Go player to have a reputation in the Western world. At a time when he was thought to be the best player in Japan, he taught the game to chemist Oskar Korschelt, a visitor from Germany. Korschelt later was the first person to popularize Go to a notable degree in a non-Asian country. Shūho is also credited with the innovation of time limits being imposed on a game of Go.
