Claude John Tozer DSO (27 September 1890 – 21 December 1920) was an Australian medical doctor and first-class cricketer who played for New South Wales.
The son of a Bank of New South Wales official, John and Beatrice Tozer (née Charlton), he was educated at Sydney Church of England Grammar School.
A right-handed batsman, Tozer juggled his early cricket career with medical studies at university and as a resident at the Royal Hospital for Women, Paddington.
[6] Tozer was due to play as NSW captain in a match against Queensland on 1 January 1921, but on 21 December, at Lindfield in Sydney, he was shot three times and killed by a depressed married female patient who had fallen in love with him.
[7] At her trial, the woman, Dorothy Mort, was found not guilty on the ground of insanity[8] but was imprisoned in Long Bay Gaol at the Governor's pleasure, and was released nine years later.
