Mike Lazaridis and Jim Balsillie of Research In Motion are known for which invention?

Insulin is one of Canada's greatest gifts to medicine. Sir Frederick Banting of Toronto and Charles Best discovered this hormone, which is used to treat diabetes. As of 2012 it was credited with saving 16 million lives around the world. Another famous name is Alexander Graham Bell. The idea for the telephone came to him at his Canadian summer home. Joseph-Armand Bombardier invented the snowmobile, a light vehicle built for travel in winter.

Everyday life around the world was changed by Canadian inventors too. Standard time zones, used across the globe, were the work of Sir Sandford Fleming. The first electric light bulb was built by two men working together, Mathew Evans and Henry Woodward. They later sold their patent to Thomas Edison, and it is Edison who is remembered, because he turned the bulb into a product people could buy. Radio owes something to Reginald Fessenden as well: nobody before him had sent a voice message by wireless.

Medicine and technology offer more examples. At McGill University in Montreal, Dr. Wilder Penfield led the way in brain surgery, and people called him "the greatest living Canadian." The first cardiac pacemaker was the invention of Dr. John A. Hopps; the device still saves lives today, in people with heart disorders. The Canadarm - a robotic arm that works in outer space - came from SPAR Aerospace and the National Research Council. And the BlackBerry was the most famous product of Research In Motion, the wireless communications company of Mike Lazaridis and Jim Balsillie.
