Edwin Binney and Harold Smith were the men responsible of the creation of the first crayolas under their Binney & Smith company which was founded back in 1885. In 1903, he proâ¦duced the first Crayola crayons and trademarked the Crayola name with the help from Binney's wife. They first sold Crayola's in June of 1903 and had a full line of boxes from a 6-color to a 30-color although their 8-color was one of their more famous assortment sizes.
Crayola did not invent the crayon. Records show that Europe was the birthplace of the modern crayon. The first crayons were made from a mixture of charcoal and oil. Later, powdered pigments of various hues replaced the charcoal. It was discovered that substituting wax for the oil in the mixture made the sticks sturdier and easier to handle. Crayola Crayons were invented by Binney & Smith in 1902 and first offered for sale in 1903. Alice (Stead) Binney, a school teacher and wife of co-founder Edwin Binney, suggested the company manufacture an inexpensive alternative to imported crayons of that era. The trade name Crayola was coined by Mrs. Edwin Binney who joined the French word craie, meaning stick of chalk and ola from the word oleaginous, meaning oily. Crayola Crayons are made primarily from paraffin wax and color pigment.
