Beatrice Shilling OBE PhD MSc CEng was a British aero-engineer and racing driver. As a young girl she developed a love of fast cars combined with a remarkable aptitude for mechanics and engineering. She bought her first motorbike aged just 14. At a time when it was extremely unusual for a woman, she worked as an apprentice at an electrical engineering company, before going to Manchester University to study engineering - one of only two women to do so. Aside from her trailblazing career, she was a succesful motorbike racer, becoming the fastest ever woman racer at the famed Brooklands circuit. As part of our celebration of International Women's Day 2020, we would like to share the story of her most famous invention.
