Louis George Duffus (13 May 1904 in Melbourne, Australia – 24 July 1984 in Johannesburg, South Africa) was a South African cricketer who became the country's most respected writer on the game.
He was educated in Johannesburg, being awarded a Bachelor of Commerce degree.
He was a fine athlete and baseballer, as well as a cricketer.
He was a right-handed batsman and occasional wicketkeeper, who played in five first-class matches for Transvaal between 1923/24 and 1934/35.
Meanwhile, he had established himself as a cricket journalist, accompanying the South African national side on their 1929 tour of England and supplying copy for a number of British papers.
Thereafter, until South Africa were barred from Test cricket some forty years later as a result of apartheid, he hardly missed a Test match in which they were involved.
He covered more than one hundred in all.
His Wisden obituary described him as "conscientious, generous and very fair, with a delightful manner and a nice turn of phrase".During the 1935 South African tour of England he was summoned from the press box to field as a substitute against Glamorgan.
He caught Dyson at slip, which helped in ensuring the tourists' victory in front of a large Swansea crowd.
He was proud that Wisden mentioned this in its match report.
He had not been far from selection for the touring party, having played in a trial match in the previous December.
He compiled and edited Volume 3 of the official history of South African cricket, covering the years from 1927 to 1947.
He also wrote on rugby union and was a war correspondent during World War II.
He was also the sports editor of the Johannesburg Star.He achieved a degree of fame in the medical world in 1970 when, though a haemophiliac, he had a hip operation in Oxford.
