Today we celebrate the work of Dr. Tin Liu, a Chinese American inventor who played a cruicial role in the development of Play-doh.
Joe McVicker took Play-Doh to an educational convention for manufacturers of school supplies, and Woodward & Lothrop, a department store in Washington, DC began selling the compound.In 1956, the McVickers formed the Rainbow Crafts Company to make and sell Play-Doh. Also in 1956, a three-pack of 7-ounce cans was added to the product line, and, after in-store demonstrations, Macy’s of New York and Marshall Field’s of Chicago opened retail accounts. In 1957, chemist Dr. Tien Liu reduced Play-Doh’s salt content (thus allowing models to dry without losing their color), and Play-Doh ads were telecast on Captain Kangaroo, Ding Dong School, and Romper Room. In 1958, Play-Doh’s sales reached nearly $3 million.
