Charles Sydney Barlow (10 May 1905 – 1 June 1979) was a South African businessman, conservationist and philanthropist who built up Barlow Rand into one of South Africa's biggest companies. In his youth, he was also a sportsman: as a cricketer he made two first-class appearances for Somerset County Cricket Club in 1925 and 1926, and as a rugby union player he won four Blues at Cambridge University from 1923 to 1926, captaining the side in his final year.
