The band-aid was created by a cotton buyer for the company Johnson & Johnson named Earle Dickson in 1921. The original intentions of it was to aid his wife, as she always cut herself, while preparing food. The band-aid started off as adhesive tape with a separate gauze to see how much is needed, depending on the size of the wound. That prototype didn't hold on long enough on his wife for the wound to heal fully, so Earle designed a new band-aid where he placed the gauze on to the adhesive tape and used crinoline to keep it sterile. James Johnson, Earles boss, found out about his invention and wanted to manufacture it for public use.
