Percy Shaw (15 April 1890 – 1 September 1976) was an English inventor and businessman. He patented the reflective road stud or “cat’s eye” in 1934, and set up a company to manufacture his invention in 1935. Shaw was educated at Boothtown Board School, and started work as a labourer in a cloth mill at the age of 13. He became apprenticed to a wire drawer, but the low wages on offer were not attractive and he soon took a series of unskilled jobs in local engineering works.
The cat’s eye is a retroreflective safety device used in road marking and was the first of a range of raised pavement markers. It consists (in its original form) of two pairs of glass cylinders with faces at the rear cut, moulded or ground to have three faces at (in three dimensions) 60 degrees to each other. Cat’s eyes are particularly valuable in fog and are largely resistant to damage from snow ploughs. Apart from the evident requirement for toughness, the glass has no other special qualities.
