About Heini Mader

German born Swiss engineer who initially got into the sport as Jo Siffert’s mechanic. A keen videographer, he took many videos in the 1960’s and 1970’s which are often now the only video recollection of some events. Mader later worked for Jo Bonnier before Bonnier’s death, and later became a tuner for BMW as well as his Megatron spell. Later ran a racing components firm which still exists and Heini, now in his eighties, is still involved. He visits historic events and also works as a car restorer.
