William Groom

1923 – 1999   Soldier, Inventor

Born in Petrolia, Ontario, Groom enlisted as a Private in the Canadian Army in World War 2. After the war, he rose through the ranks over a long career and retired a senior officer. Following his retirement, he was hired by Canada Post as a computer expert and was central to the development of the Canadian postal code system, helping to streamline and automate the mail requirements of a rapidly growing nation. It was at his suggestion that the repeating capital letter-number format was adopted; although less convenient, the intent was to reduce errors by forcing users to slow down and pay attention to detail.  He spent many years working with the Boy Scouts and as a volunteer swimming instructor for disabled youth.
