Ken Tyrrell
Besides Formula One cars, Cooper offered a series of Formula Junior cars. These were the T52, T56, T59, and T67 models. Ken Tyrrell ran a very successful team with John Love and Tony Maggs as his drivers. Following the demise of Formula Junior, Ken Tyrrell tested Jackie Stewart in a Formula Three car, a Cooper T72. This test at the Goodwood Circuit marked the start of partnership which dominated motorsport later on.
