Edwin Binney (1866–1934) is best known for his invention (along with his cousin C. Harold Smith) of the Crayola crayon. In 1885, Binney took control of his father’s business, Peeksill Chemical Co. While experimenting with a mixture of slate waste, cement, and talc, Binney created the first dustless white chalk. The invention was awarded a gold medal at the St. Louis World’s Fair in 1904. It was only one year later, in 1905, that Binney & Smith produced the first box of Crayola crayons.
