In what year were crayons introduced?
There is no "one year" that can be established for the invention of the crayon. Encaustic crayons go back to the Greeks. Modern crayons can be traced back to the mid 1800s. THe first commercial crayons available in the United States came from companies like Eagle Pencil, Franklin Mfg. Co, Milton Bradley, Dixon Ticonderoga, Standard Crayon and Prang. These were all available between 1876 and 1900; several years before Crayola was invented. Europe had crayons from Germany and France going back into the mid 1800s as well.
