In 1934, the late Percy Shaw almost crashed while driving home from the pub on a foggy night in West Yorkshire, in England.

He was saved when his headlights were reflected in the eyes of a cat and it gave him a brilliant idea. He invented reflective studs for the road and called them cat’s eyes.

Percy’s great-niece, Glenda Shaw remembers the eccentric inventor.
