Little Mo — the first woman to complete the calendar Grand Slam, a champion cut short by tragedy.

Maureen Connolly was born on 17 September 1934 in San Diego, California. Nicknamed 'Little Mo' (after the battleship USS Missouri), she was a prodigious talent who won 9 Grand Slam singles titles before the age of 20. In 1953 she became the first woman to complete the calendar Grand Slam. Tragically, a horse-riding accident in 1954 ended her playing career. She subsequently worked in coaching and died of cancer in 1969 aged just 34. She is widely regarded as one of the greatest players of all time despite her brief career.
