Although Canadians have made more improvements and advances in inventions than individual inventions, Canadian inventors have contributed more than they are generally given credit for. Canadian inventors have contributed to society for hundreds if not thousands of years. Among the many pre-World War II Canadian inventions are the telephone invented by Alexander Graham Bell in 1876, the light bulb invented by Henry Woodward and Mathew Evans in 1874, and Plexiglas co-invented by William Chalmers in 1931. Canadian inventors and engineers of World War II continued to contribute to the world by working on projects that would greatly alter and improve the technology of modern society. Canadian inventors and engineers have exclusively contributed to and developed many inventions. Some Canadian inventions have been revolutionary, such as keyframe animation, invented in 1969 by Nestor Burtnyk and Marceli Wein which revolutionized 3D animation, or the electric wheelchair invented by George Klein in 1952. Other Canadian inventions have been less revolutionary, like the retractable handle for beer cartons. invented by Steve Pasjack in 1957, or Trivial Pursuit invented by Chris Haney and Scott Abbott in 1979, which while fun wasn't exactly revolutionary. Canadians have made many developments and while recognition has been given for inventions like the Canadarm, there has not been widespread recognition for many Canadian inventions that have also been of great importance. Java Programming Language was invented by James Arthur Gosling of Calgary, Alberta in 1994. Java is a platform-independent language that allows entertainment systems to communicate with each other. Java was a revolution... middle of paper... up to 266,000 kilograms in space. The Canadarm also established Canada's great reputation for technological and robotic innovation. Despite the Canadarm recognition there are many Canadian inventions that are not recognized as Canadian and perhaps the lack of recognition is due to a lack of bragging rights. However, there are many less important inventions that are recognized, which does not explain why important inventions have been excluded from Canadian classrooms and common knowledge. Many of these inventions were featured in mental_floss' article 19 Things You May Not Know Were Invented in Canada. This shows that this is a part of Canadian history that has been somewhat lost. Perhaps the article shows not only some interesting trivia, but also the fact that people should recognize the innovation of great but unsung inventors.
