The first totally disposable diaper in the U.S. was introduced by Proctor & Gamble in 1961. The company had purchased the Charminâ Paper Company in 1957, and they assigned one of their chemical engineers, Victor Mills (1897-1997), to look into creating new paper products.
The company launched the new diaper as Pampers. Throughout the rest of the 1960s and the 1970s, Pampers built significant unit volume and dollar sales by converting cloth-diaper users to disposables users. P&G effectively created a new category and easily won a leading share in it.
