The light bulb is a good example. Edison is credited by many, but in
looking at the issue in more detail, you will find that he bought a
patent from a Canadian inventor, who had the essential idea, and was
perhaps 90 percent of the way to a practical product. Edison then
perfected the filament and gas in the container. So who was the inventor?
