Non-toxic wax crayons for children were invented by the American company, Binney and Smith. These were Crayola crayons and by the beginning of the twenty-first century the company was the world's largest manufacturer of crayons. The first pack was produced in 1903 and featured eight colours - black, brown, blue, red, purple, orange, yellow, and green. The word Crayola was created by Alice Stead Binney, wife of Edwin Binney one of the company's founders. She combined the French words for chalk, craie, and oily, oléagineux. The Crayola company, as it became known, is also famous for Silly Putty.
