Joseph Davis 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 the help of 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 world championships from 1927 to 1946, and he is the only undefeated player in World Snooker Championship history. In 1935, he scored the championship's first century break. A professional English billiards player from the age of 18, Davis was World Billiards Champion four times between 1928 and 1932. He was the first person to win world championship titles in both billiards and snooker. After his 1946 victory, Davis no longer played in the World Snooker Championship but he participated in other tournaments and exhibition matches until 1964, winning four News of the World Snooker Tournament titles. He also continued to wield considerable influence over the professional game through his chairmanship of the professional players' association, his co-ownership of the Leicester Square Hall venue, and his negotiation of television contracts. His younger brother, Fred Davis, was the only person to defeat Joe Davis in a competitive snooker match without receiving a start. In 1955, Davis was the first player to make an officially recognised maximum break. He collapsed whilst watching his brother Fred play Perrie Mans in the semi-final of the 1978 World Snooker Championship. During his convalescence, Davis contracted a chest infection which led to his death on 10 July that year.
