Earle Dickson invented this protective cover made of adhesive for cuts and sores, with the intention of saving the fingers of his wife. Earle Dickson worked as a cotton checker for the firm of Johnston and Johnston when he invented the band-aids 86 years ago in 1921. His wife, Josephine Dickson was always cutting her fingers when she prepared meals in the kitchen.In those days, covering a wound was done by using a piece of gauze with adhesive tape placed on top to keep it in place. Earle Dickson noticed that the gauze and adhesive tape that his wife used fell off in no time because of the work she had to do with the fingers. So he decided that there had to be a way of protecting small wounds more effectively..
