Sir Sandford Fleming FRSC KCMG (January 7, 1827 – July 22, 1915) was a Scottish Canadian engineer and inventor. Born and raised in Scotland, he emigrated to colonial Canada at the age of 18. He promoted worldwide standard time zones, a prime meridian, and use of the 24-hour clock as key elements to communicating the accurate time, all of which influenced the creation of Coordinated Universal Time.[1] He designed Canada’s first postage stamp, produced a great deal of work in the fields of land surveying and map making, engineered much of the Intercolonial Railway and the first several hundred kilometers of the Canadian Pacific Railway, and was a founding member of the Royal Society of Canada and founder of the Canadian Institute (a science organization in Toronto).

By 1871, the strategy of a railway connection was being used to bring British Columbia into federation and Fleming was offered the chief engineer post on the Canadian Pacific Railway. Although he hesitated because of the amount of work he had, in 1872 he set off with a small party to survey the route, particularly through the Rocky Mountains, finding a practicable route through the Yellowhead Pass. One of his companions, George Monro Grant wrote an account of the trip, which became a best-seller.[9] In June 1880, Fleming was dismissed by Sir Charles Tupper, with a $30,000 payoff.[8][10] It was the hardest blow of Fleming’s life, though he obtained a promise of monopoly, later revoked, on his next project, a trans-pacific telegraph cable.[8] Nevertheless, in 1884 he became a director of the Canadian Pacific Railway and was present as the last spike was driven.
