Band-aid is considered one of the most brilliant inventions in medical history. A simple but effective creation that supports the treatment of small cuts and scrapes. They were invented by Earle Dickson.

Earle Dickson was not an inventor, he took on the job of buying cotton for Johnson & Johnson. The invention of the personal tape came from his care for his wife.
In 1917, after getting married, Earle Dickson noticed that his new wife was constantly cutting her fingers while cooking in the kitchen. Earle Dickson also felt that the large gauze pads he used to stop his wife's bleeding were too large and unsightly. He then came up with an idea to help treat his wife's injury from his own home. He took bandages and gauze and combined them to create the first bandage. He created a pattern of cotton gauze and a piece of adhesive cloth coated with a border that can be peeled off to reveal the adhesive, allowing the gauze and adhesive cloth to cover the wound.

Johnson & Johnson supported this idea by Earle Dickson and called the product the Band-Aid. Through many historical ups and downs and improvements, "Band-Aid" gradually became the common name for personal band in many parts of the world.The original handmade Band-Aid did not sell well, selling only $3,000 in its first year (1921). This may be because early versions of the Band-Aid had sections that were 6.3 cm wide and 45.7 cm long. The user must cut off the length of bandage needed to cover the wound, a process that is considered "bulky".Improvements are quickly applied. Machine-made Band-Aid in various sizes was introduced in 1924. Sterilized bandages were introduced to the market in 1939. Thin vinyl version was introduced in 1958.

Earle Dickson died in Ontario, Canada, on September 21, 1961 at the age of 68. After his groundbreaking contribution, he remained with Johnson & Johnson until his retirement in 1957. By the time of Earle Dickson's death, the company was selling $30 million worth of Band-Aid a year. According to Fox News, the company currently produces 10 million Band-Aids per day.
