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.

Snooker is a cue sport played on a rectangular billiards table covered with a green cloth called baize, with six pockets, one at each corner and one in the middle of each long side. First played by British Army officers stationed in India in the second half of the 19th century, the game is played with twenty-two balls, comprising a white cue ball, fifteen red balls, and six other balls—a yellow, green, brown, blue, pink, and black—collectively called the colours. Using a cue stick, the individual players or teams take turns to strike the cue ball to pot other balls in a predefined sequence, accumulating points for each successful pot and for each time the opposing player or team commits a foul. An individual frame of snooker is won by the player who has scored the most points. A snooker match ends when a player reaches a predetermined number of frames.
