Year Invented: 1917-1921
Designer: Earle Dickson
Earle Dickson worked for Johnson & Johnson, and he also had a very clumsy wife. This aided Dickson in creating one of the best-selling bandages ever. Sales were initially slow; they only sold $3,000 worth of Band-Aids the first year, but once Johnson & Johnson decided to give free Band-Aids to Boy Scout troops as a publicity stunt, the sales started picking up. Now the company says that sales have topped over $100 billion.
