An unknown inventor, probably 2 500 years ago, in the ancient Roma. Having been lost for centuries, it was independently discovered again in the late 19th century in Nevada, USA, by Joseph Cartwright. Cartwright and his business partner, Joseph Dixon, commericalized the product by embedding it inside of wooden sticks cut from the numerous pine trees on Cartwright's ranch. The Dixon-Ticonderosa pencil was thus born and sold throughout the western United States, and it remains a strong player in the global pencil industry to this day.
The "Love Sharpener", was designed by John Lee Love of Fall River, MA. Love's invention was the very simple, portable pencil sharpener that many artists use, the pencil is put into the opening of the sharpener and rotated by hand, and the shavings stay inside the sharpener. Love's sharpener was patented on November 23, 1897 (U.S. Patent # 594,114). Two years earlier, Love created and patented his first invention the "Plasterer's Hawk." This device which is still used today, is a flat square piece of board made of wood or metal, upon which plaster or mortar was placed and then spread by plasterers or masons. This was patented on July 9, 1895.
Before pencil sharpeners people used a knife to sharpen the point of the pencil
The first patent for a mechanical pencil sharpener (as opposed to a sharp knife) was taken out by French mathematician Bernard Lassimone in 1829. It was French patent #2444. It should be noted a patent doesn't mean it was made, just designed.
Therry des Estwaux of France invented what we would call the first mechanical pencil sharpener about 35 years later in 1849.
Bangor, Maine is the proud home of the first American designed pencil sharpener. Walter K. Foster designed one in 1855.
Believe it or not the first electric sharpeners date back to around 1917.

Raymond Lowery invented the electric pencil sharpener in the early 1940's. In an electrical pencil sharpener, the cylindrical cutter is rotated by an electric motor.
William Monroe invented the first American wooden pencil in 1812

There is no lead in pencil - Pencil is made from graphite
