Robert Samuel McLaughlin (1871-1972)
A famous industrialist and philanthropist, "Colonel Sam" McLaughlin was a founder of the automotive industry in Canada. Involved in the manufacture of carriages and sleighs for his family business, he foresaw the importance of the automobile and adapted his McLaughlin Carriage Works for automotive production. He partnered with Buick Motor Company in 1907 and later with Chevrolet. In 1918, his companies were incorporated into General Motors of Canada. His shrewd business skills led to a vice-presidency at the American parent company, confirming his strong ties with this industrial giant, and his leadership of it in both countries.
