When were Pampers disposable diapers invented?

In 1956, P&G researcher Victor Mills disliked changing the cloth diapers of his newborn grandchild. So he assigned fellow researchers in Proctor & Gamble's Exploratory Division in Miami Valley, Ohio, to look into making a better disposable diaper. Pampers were introduced in 1961. They were created by researchers at P&G including Vic Mills and Norma Lueders Baker. The name "Pampers" was coined by Alfred Goldman, Creative Director at Benton & Bowles, the first ad agency for the account.

These early diapers were bulky, heavy products composed of fluff pulp with a rayon topsheet, polyethylene backsheet. In 1966, Pampers launched a 'wingfold' design and by 1969 started a "third size". By this time, Pampers had become a national brand in the United States. Procter and Gamble replaced the pin-on design with tapes in 1971.
