Colin M. Snedeker (January 5, 1936 – October 22, 2016) was a British-born American chemist best known as the inventor of the first washable crayons. Snedeker developed the washable crayon while working as a chemist for Binney & Smith, which was the parent company of Crayola crayons at the time, in response to complaints from parents and consumers. He won the patent for the washable solid marking composition utilized in the crayons in 1990. He also developed products for Kiwi shoe polish and DuPont.
