I have heard that Bernard Boyer, former Matra engineer, died on 19th March at 83 years old. He was responsible, amongst others, for the Matra with which Jackie Stewart won his first World Championship in 1969. He also raced quite successfully in Formula Junior, including driving a Lotus 18 in 1960 for the EdGer team with Henri Grandsire. I met him quite a few times when it appeared that I owned his old car. I understand that after he retired from designing F1 cars, he continued working for Matra, but on missiles!
