Brian Raubenheimer was born in Pietermaritzburg in KwaZulu-Natal. He was an amateur racing driver and manufactured the Mini Marcos kit car under licence in South Africa.
In 1965 he tried to enter his 1962 Lotus 20 Formula Junior into the South African Grand Prix but could not get the budget together to pay for a suitable engine.
The following year he entered the South African F1 Championships with a Ford 105E motor installed. He did not appear at the South African Grand Prix at East London on January the first. He was also missing from the round at Killarney a week later.
He finally made an appearance at Easter Grand Prix on the 11th April at the Roy Hesketh Circuit. Unfortunately he retired from the first heat with engine trouble which spelt the end to his weekend.
In June he contested the Natal Winter Grand Prix at Roy Hesketh once again retiring after 37 laps of the 66 lap race. He next entered the Pat Fairfield Trophy also at Roy Hesketh and also retiring again after spinning out of heat 2.
With that he decided that he had had enough of F1 and retired occasionally making appearances in saloon and sports cars racing a 1.3 Mini-Marcos with Jem Marsh at the Rand Daily Mail Nine Hours in 1967. They finished 15th overall.
He currently farms in the Pietermaritzburg area.
