—Edward Goodrich Acheson (March 9, 1856 - July 6, 1931) was a American chemist. Born in Washington, Pennsylvania, he was the inventor of carborundum, and later a manufacturer of carborundum and graphite. Thomas Edison put him to work on September 12, 1880 at his Menlo Park, New Jersey laboratory under John Kruesi. Acheson experimented on making a conducting carbon that Edison could use in his electric light bulbs.

In 1884, Acheson left Edison and became supervisor at a plant competing to manufacture electric lamps. It was here he began his own experiments on methods for producing artificial diamonds in an electric furnace. He heated a mixture of clay and coke in an iron bowl with a carbon arc light and found some shiny, hexagonal crystals (silicon carbide) attached to the carbon electrode. 1884 (MDCCCLXXXIV) is a leap year starting on Tuesday (click on link to calendar) of the Gregorian calendar (or a leap year starting on Thursday of the 12-day-slower Julian calendar). ...

Carborundum is silicon carbide and it is created by electronically fusing clay and carbon. It is the second hardest surface next to diamond.
