In 1885, Edwin Binney and his cousin C. Harold Smith (above) took control of
the Peekskill Chemical Company and re-named it Binney & Smith. While doing 
experiment with a mixture of slate waste, cement, and talc, Binney created the 
first dustless white chalk. His invention was awarded a gold medal at the St.
Louis World’s Fair in 1904. It was one year later that Benny & Smith
produced the first box of Crayola crayons (shown below).
