Sandford Fleming wanted to make the world a less chaotic place, and for everyone to agree on one thing; what time it was.
Historically, regions used solar time to set their own clocks. But after missing a train because the time had been printed as p.m instead of a.m, Fleming proposed a 24 hour clock, centered on Greenwich and with the world divided into 24 time zones.
The concept was adopted at the International Prime Meridian Conference in 1884, attended by 25 nations.
Fleming was also known for helping build the Intercontinental Railway, serving as chief engineer of the Canadian Pacific Railway, and designing Canada’s first postage stamp.
Google’s doodle on 7 January, the 190th anniversary of his birth, was in honour of his legacy.
