John Monckton

John James Monckton (28 October 1938 – 29 June 2017) was an Australian backstroke swimmer who won a silver medal in the 100-metre event at the 1956 Summer Olympics in Melbourne. Although he set multiple world records, he never won an Olympic gold medal.

An apprentice carpenter from the New England region of New South Wales, Monckton appeared to be primed to win gold at the 1956 Olympics. At the national team camp in Townsville before the games, he became the first person to swim 400-metre backstroke in under five minutes. Although it was not a regularly contested event at international level, it was a promising sign for the event to be included for medal competition in the Olympics. He also set world records in the 110- and 220-yard freestyle events.

At the Olympics, Monckton was the fastest qualifier in the heats and semifinal, but was upstaged in the final by teammate David Theile. Monckton continued competing in the hope of reaching a third Olympics in 1964, but retired after his performances began to deteriorate.

He married Maureen Giles, an Australian swimmer at the 1956 Olympics.

He was inducted into the Sport Australia Hall of Fame in 1999.

The Monckton Aquatic Centre in his hometown of Armidale is named for him.
