John Alfred Leach MBE was a British table tennis player, coach, and author. He began competing at a relatively old age, 17, before serving in World War II. During the war, he greatly elevated his game and, in 1946, achieved a world ranking. In 1949, Leach became Great Britain's second World Champion singles player. After winning the title, he achieved widespread fame within the United Kingdom, appearing on television and writing for News of the World. Two years later, Leach added a second singles title. In 1953, he was part of the team that won Great Britain's first, and as of 2023 only, team World Championship. He also won 13 bronze and silver World championship medals between 1947 and 1955. As of 2014, Leach is just one of 11 players from any country to win two singles championships.
