Keep Working Until You Find A Solution

Do you keep working if your first ideas fail?

In 1948, graduate students Bernard Silver and Norman Joseph Woodland joined forces to develop a method for automatically reading product information in a store. Their first idea was to print information using ink sensitive to ultraviolet light, but the system was too unstable and would be too expensive to sell.

They returned to the drawing board and in 1949 filed their patent application for bar codes. In 1974, the first commercial bar code reader was installed at a supermarket in Troy, Ohio. The first coded product was Wrigley’s® gum.
