Sir Sandford Fleming

Born 7 Jan 1827; died 22 Jul 1915 at age 88.Scottish surveyor and leading railway engineer who divided the world into time zones. He emigrated at age 17 years to Quebec, Canada, on 24 Apr 1845, as a surveyor. Later he became one of the foremost railway engineers of his time. While in charge of the initial survey for the Canadian Pacific Railway, the first Canadian railway to span the continent, he realized the problems of coordinating such a long railway. This lead him to the idea of time zones, which contribution to the adoption of the present system of time zones earned him the title of "Father of Standard Time." Fleming also designed the first Canadian postage stamp. Issued in 1851, it cost three pennies and depicted the beaver, now the national animal of Canada.
