The first crayons consisted of a mixture of charcoal and oil. In the early 1900s, cousins Edwin Binney and Harold Smith developed a nontoxic wax crayon. Binney’s wife, Alice, attached the French word for chalk, craie, with “ola,” from oily, to form the Crayola brand name. Their first box of Crayola crayons were sold for a nickel in 1903.
