Joseph Davis OBE (15 April 1901 – 10 July 1978) was an English professional snooker and English billiards player. He was the dominant figure in snooker from the 1920s to the 1950s and has been credited with inventing aspects of the way the game is now played, such as break-building. With equipment manufacturer Bill Camkin, he drove the creation of the World Snooker Championship by persuading the Billiards Association and Control Council to recognise an official professional snooker championship in 1927. Davis won the first 15 championships from 1927 to 1946 and remains the only undefeated player in World Snooker Championship history. He scored the championship's first century break, in 1930.
