Sir Sandford Fleming (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.
He designed Canada's first postage stamp, left a huge body of surveying and map making, engineered much of the Intercolonial Railway and 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.
