My partner, Christopher Hanson-Abbott, who has died aged 92, devoted much of his life to making the world a safer place. A pioneer of vehicle safety technology, he introduced reversing alarms from Japan to Britain and later helped develop broadband reversing alarm technology that has saved countless lives worldwide.
Born in Alexandria, Egypt, Chris was the son of Clifford Hanson-Abbott, an RAF officer, and Edna (nee Johnson), a good club golfer.
