James Paris Lee of Galt (Cambridge) is known for his part in inventing the Lee-Metford and Lee-Enfield Rifles. The question remains if he had a role in inventing the Remington typewriter. The company that made Lee's rifles also made Remington Typewriters. While he's not officially recognized, it's believed that he may have been involved. Often only the main contributors to an idea receive credit even though countless minds are involved.
