More Canadian Inventions

The paint roller was invented about 1940 in Toronto by Norman Breakey, but he died before being able to patent his invention. The first paint roller patent was held by American Richard Croxton Adams.
The pager was invented by Alfred J. Gross, a Toronto-based wireless communications pioneer, during 1949. Gross is also often credited as the inventor of the walkie-talkie, a distinction he sometimes shares with fellow Canadian Donald Hings, who is also credited for having created the two-way radio during 1939.
The first internet search engine, Archie (Archive without the V), was created by Alan Emtage at McGill University about 1988.
Basketball was invented by Canadian James Naismith, born in Ontario and educated at McGill University, but he did not invent it in Canada. He invented the sport while working as a physical education instructor at a YMCA in Massachusetts during 1891.

The first electric wheelchair was developed by George Klein, during 1953. The Ontario-born inventor also developed aircraft skis, the M29 Weasel army snowmobile/ATV, the microsurgical staple gun, the ZEEP nuclear reactor, a scientific language for snow and more.

Five Canadian Inventions

Here are a few things many do not know were invented in Canada.
Peanut Butter - Although American agricultural pioneer George Washington Carver is often credited for inventing peanut butter, the first patent for the spreadable substance was actually given to Montreal, Canada’s Marcellus Gilmore Edson in 1884.
IMAX - Canadian filmmakers Graeme Ferguson and Roman Kroitor first pioneered the technology of high-resolution images on huge screens at Montreal’s Expo ’67.
Hockey Mask - No surprise with this one. The hockey mask, which has helped keep many a goaltender’s face intact, was first worn regularly by Montreal Canadiens player Jaques Plante in 1959.
World Time Zones - Canadian railroad engineer Sandford Fleming came up with the idea of creating 24 time zones across the entire globe, which would form “international standard time.” In 1884 at the International Meridian Conference in Washington, D.C., his ideas were eventually adopted worldwide.

Trivial Pursuit - During 1979, Montreal Gazette picture editor Chris Haney and sports journalist Scott Abbott came up with Trivial Pursuit, which became the biggest phenomenon in game history, with over 100 million copies of the game sold.
