In the early 1900's, Milton inventor and businessman Peter Lymburner Robertson (1879-1951) established the Robertson Manufacturing Company in the town of Milton and began producing the Robertson screw and screwdriver - at the time, a unique square recess impression in the head of a screw. It was a revolutionary change in the fastener industry. The first patent was issued in 1909 and the last patent expired 55 years later in 1964. His firm was the largest employer in Milton for more than 50 years. Robertson screws and screwdrivers carry his name to this day.An innovator, industrialist and astute businessman, Robertson's products became widely used, from the wooden bodyworks of Henry Ford's model T to ships built by the British Navy in WWII. Robertson Manufacturing Company also became one of the first firms in the fastener business to pre-package screws and nails. Robertson's 40-year career transformed the Haldimand Country farm boy into a millionaire-philanthropist. He remained in control of his company until his death in 1951.
