Peter Lymburner Robertson (1879– September 28, 1951) was a Canadian inventor, industrialist, salesman, and philanthropist who popularized the square-socket drive for screws, often called the Robertson drive. Although a square-socket drive had been conceived decades before (having been patented in 1875 by one Allan Cummings of New York City, U.S. Patent 161,390), it had never been developed into a commercial success, because the design was difficult to manufacture, and Robertsons efficient manufacturing technique using cold forming for the screws head is what made the idea a commercial success.[1] He produced his screws (patented in Canada in 1909) in his Milton, Ontario factory starting in 1908. The brand has been sold over the years,[2] and the manufacturing for the present corporation (Robertson Inc.) is done in Jiaxing, Zhejiang, China; but the Milton, Ontario, building is still a head office.[3] Robertson also wrote a book (short title The Remedy, 1932)[4] which suggested a strategy to end the Great Depression. It discussed topics including national debts, currencies, and the gold standard.
