Canadian Inventors and Engineers - 870 Words

Although Canadians have made more improvements and advances on inventions rather than solo inventions, Canadian inventors have contributed more than they are generally given credit for. Canadian inventors have been making contributions to society for hundreds if not thousands of years. Among the many Canadian inventions prior to the Second World War are the telephone which was 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. After the Second World War Canadian inventors and engineers continued to contribute to the world by working on projects that would alter and vastly improve the technology of modern society.

Instant replay was first implemented by George Retzlaff, a Toronto-based producer of CBC’s Hockey Night in Canada in 1955. Instant replay was not used in America until December 7th, 1963 for the Army-Navy football game, eight years after the first use in Canada. This invention was not used widely when it was originally implemented because it was not as instant as the name would lead one to believe. However after it was perfected it became widely used in many sports to determine controversial calls and to give fans a second look at a play. In modern day it is used so often that viewers may not even realize its significance however its invention was a major development in sports. As mentioned before there are many Canadian developments that were based on previous discoveries. An example of this is the Alkaline-Manganese battery, invented by Lewis Urry in the early 1950s and patented in 1959. Urry based his invention on the earlier work of Thomas Edison. The cell lasted five to eight times longer than its predecessors. This battery is the base of most if not all modern batteries. Another example is the electric wh eelchair which was invented by George Klein after the Second World War to assist the many severely injured veterans returning home. Klein increased the voltage of the electric dive and replaced the single drive with two.

According to CVCA (Canada’s Venture Capital and Private Equity Association), the worldwide risk investment in Canada dropped by 22% to $380 million in 2012, although overall investment remained stable at $1.5 billion in 2011. Thus, Canadian research based Nano-biotech firms are often the target of foreign buyers as risk capital in Canada is lower than United States. Alberta is seen as the id eal destination for funding by the Venture Capitalists.

An engineer must be able to express their own ideas not only verbally, but also visually through the creation and design of said idea. Essentially, an engineer must possess the capabilities to use their designing ability to solve real world problems which affect other people every day. Solving significant problems which affect society is just one of the many responsibilities which pertain to being an engineer. For example, a community may have a problemRead MoreHistory of the Propeller1574 Words   |  7 PagesPaucton envisioned a flying machine that had two airscrews, one for propulsion and the other for sustaining flight. The idea of using an airscrew for propulsion was utilized during the late 1700’s to early 1800’s. Only after experimentation did the inventors conclude that more propulsive power could be obtained by merely straightening out the surface of the airscrew blades. Attempts to utilize the â€Å"straight blade† propeller were made by balloonists. These contraptions were quite strange and hardly fulfilledRead MoreBrief Account Of The Life And Invention Of Lewis Frederick Urry1525 Words   |  7 PagesThe aim of this report is to give a brief account of the life and invention of Lewis Frederick Urry. As the subject of my report, a literature search was carried out to identify facts and relevant information. Lewis Frederick Urry became a Chemical engineer in the 1950 and was the very first person to fabricate alkaline batteries. In conclusion he made a significant contribution in the field electrochemistry and battery technology in the 20th century.
