Four years later, a Westport housewife named Marion Donovan developed a waterproof diaper cover known as the "Boater" using a sheet of plastic from a shower curtain; she was granted four patents for her invention, including the use of plastic snaps as opposed to safety pins. In 1947, a man named George M. Schroder invented the first ever diaper with disposable nonwoven fabric. Disposable diapers were introduced to the US in 1949 by Johnson & Johnson.
During the 1950s, companies such as Kendall, Parke-Davis, Playtex, and Molnlycke entered the disposable diaper market. In 1956, Procter & Gamble began researching disposable diapers. Vic Mills, along with his project group including William Dehaas, both men who worked for the company, invented "Pampers" while searching for a better product to use.
