Who invented baby diapers?
I think they just evolved into their current state just like tech and medicine have evolved over the years. When I was little we didn’t have disposable diapers (in the former Soviet Union in the 80s) so I had old cloths used as diapers that later were used to mop the floors with! Yikes! But sorry I do not know the answer to your question the way you’d expect, with the name of a person.
