Great Canadian Inventors from the 1920s
Canadians rarely recognize their inventive genius and … the vast majority of these geniuses derive little financial gain from their brainchild. … Like so much of Canadian history, the story of our technical achievements has largely gone unchronicled. … Perhaps … we have simply underestimated our own native ingenuity. Self-‐effacement [avoiding drawing attention to oneself] has long been considered a Canadian trait; inventiveness has not. Source: Pierre Berton, cited in J.J. Brown, The Inventors: Great Ideas in Canadian Enterprise (Toronto) McClelland & Stewart, 1967), p. 7.

Banting & Best: Charles Best (left) and Frederick Banting pose in the above picture with one of the dogs used in their groundbreaking research that found a treatment for diabetes. Banting had thought of using a hormone produced by the pancreas to treat people with diabetes. Their discovery of insulin has saved millions of lives and is one of the greatest medical discoveries of the 20th century. However, they did not profit from their work. They sold their idea to the University of Toronto for just $1. The university then licensed drug companies to make insulin and used the fees for medical research. For reflection: 1. Do you think they made the right decision when they sold their idea for just $1? Why or
why not? 2. Why do you think that they made this decision?

Patents and Innovation For Reflection: 1. a) Of the five inventors that we studied who do you think is the most famous? b) Why? 2. a) Of the five inventors that we studied who do you think is the richest? b) Why? 3. If you were a great Canadian inventor what would you do with your ideas? Would you
protect your invention though an application for a patent or would you share them so that everyone can benefit from your discovery?
