The pencil eraser was patented in Philadelphia, Pennsylvania, by Hymen Lipman, a Jewish immigrant from Kingston, Jamiaca, on this day in history, March 30, 1858.
Philadelphia inventor Hymen L. Lipman rushed heroically to the aid of mistake-prone schoolchildren, draftsmen and artists everywhere when he secured the patent for the pencil with eraser on this day in history, March 30, 1858. 'Be it known that I, Hymen L. Lipman, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful Lead-Pencil and Eraser;' the visionary wrote in his patent application.
Although resembled coal, it would not burn,' reports the University of Waterloo Earth Sciences Museum. 'It did, however, prove to be an excellent marker of sheepskins.' Graphite also boasted one major advantage over the lead used in earlier pencils: graphite is not no poisonous. 'A market for it opened up around the end of the sixteenth century.
Although commonly referred to as the lead pencil, even in Lipman's patent application, they are actually made of non-toxic graphite. 'Nuremberg, Germany, was the birthplace of the first mass-produced pencils in 1662. Spurred by Faber-Castell , Lyra, Steadtler and other companies, an active pencil industry developed throughout the 19th century industrial revolution,' reports Pencil.com, published by pencil-wood supplier California Cedar Products Co.
