History provides numerous examples of what could be called “accidental” inventions– inventions that were discovered or developed for one problem or purpose while the inventor was working on something else. Examples include penicillin and the slinky, among reported others.
An article at the Smithsonian explains the origins of Play-Doh. The creation of the Play-Doh material was not an accident. Instead the product owner found a new use for an existing product.
The existing product was a compound originally used for wiping and removing soot from wallpaper. Demand was falling for this product as fuel sources for heating moved from dirtier coal to cleaner oil, gas, and electricity. Joseph McVicker’s company selling the wallpaper cleaner was struggling when his sister-in-law Kay Zufall, a nursery school teacher, found children liked molding the pliable compound into various shapes. Play-Doh as a childern’s product was born.
Zukfall, as a teacher, saw the world and the product differently from her perspective working with children. Something that was probably not obvious to McVicker. This is an example of an idea born not from solitude, but from a mix of perspectives.
