The Band-Aids are one of those weird inventions that are a lifesaver. Earle Dickson developed them in the 1920s, in order to create a bandage his wife could apply to herself. The Band-Aid was a big part of our childhood, since many of us spent the entire summer with band-aids plastered all over our knees. The earlier make was 3 inches wide, and 18-inches long. They had the environment in mind, because once the tins were used for the band-aids, they could be reused for anything like storing pens, money, and even sunglasses. Some bandage companies are bringing this tin idea back (Band-Aid).
