happy pencil day!

on this day in 1858 hymen lipman of philadelphia received a patent for his revolutionary invention. by incorporating an eraser into a pencil he changed the course of pencil history!

mr. lipman sold his patent to joseph reckendorfer for $100,000 who subsequently took legal action against the venerable farber castelle for patent infringement. as a result of the supreme court ruled against him revoked the patent in 1875 saying it was not a new invention.

it is a mystery to me when securing a small rubber eraser with a ferrule (that's the little metal band) to the the top of a standard pencil became fashionable or if the myth of why so many pencils are yellow is true. still, i'm celebrating with a rousing chorus of charlotte's heartfelt vocal tribute to the #2 pencil.

happy pi day!

sing along if you know the words!
