Generations of children have grown up rolling, squishing, and shaping colorful lumps of Play-Doh into imaginative figures. Yet, the ubiquitous toy almost never became a toy at all. It took the creativity and educational insight of a nursery school teacher named Kay Zufall to transform an industrial wallpaper cleaner into one of the most famous children’s pastimes in history.
From Wall Cleaner to Classroom Clay
In the mid-1950s, a Cincinnati-based soap company called Kutol Products was facing financial hardship. Their primary product—a pasty, pliable compound designed to roll soot and coal residue off wallpaper—was losing demand as more homes transitioned to cleaner heating fuels like gas and oil.
Enter Kay Zufall, a nursery school teacher and the sister-in-law of Kutol executive Joe McVicker. Zufall read an article about how people were using the wallpaper putty as a modeling material for arts and crafts. Realizing its potential, she decided to test the non-toxic substance out with her young students.
The children loved it. Instead of traditional, stiff modeling clay that was often difficult for small hands to manipulate, the soft putty was easy to mold, clean, and endlessly reusable. Zufall immediately recognized that the cleaning product had a second, far more lucrative life as an educational toy.
Naming an Icon
When Zufall contacted her brother-in-law to share the exciting classroom success, she also brought a critical element for its commercial launch: its name.
- The Original Idea: The company had initially considered calling the product “Kutol’s Rainbow Modeling Compound.”
- The Breakthrough: Zufall and her husband felt that name was far too clinical and uninspired, suggesting “Play-Doh” instead—pairing what children did with the material with a shortened, snappy version of “dough.”
Her instincts proved entirely correct. The newly rebranded Play-Doh went on to capture the global market, becoming a staple of childhood creativity and shaping an entire multi-billion-dollar industry. Despite her pivotal role in recognizing the compound’s potential and christening it with its legendary name, Zufall’s crucial contribution remained a quiet piece of toy history for decades.
