Lovely capsule history of Play-Doh. I hadn't realized they'd given up the lovely old-time cardboard containers! Gutted!
50 years ago U.S. Patent No. 3,167,440 was granted to Noah McVicker and Joseph McVicker for a "plastic modeling composition", (which was originally intended to be a wallpaper cleaner) now called Play-Doh. Little did they know that they had created the substance of childhood memories as well as many a childhood meal, unfortunately….
Originally, Play-Doh came in only one color; off-white and came in a 1.5.lb cardboard can. Joe McVicker of Kutol Chemicals had learned from a teacher that modeling clay used by children in the classrooms was often too difficult for many of the smaller children to manipulate. He remembered that his non-toxic composition he had created as a wallpaper cleaner was easy to manipulate and could possibly work as a substitute for the typical modeling clay the schools were using.
