Did You Know...
...that the Band-Aid Bandage was invented by a Johnson & Johnson employee whose wife had cut herself? Earl Dickson's wife was rather accident prone, so he set out to develop a bandage that she could apply without help. He placed a small piece of gauze in the center of a small piece of surgical tape, and what we know today as the Band Aid bandage was born!
