It's been more than 150 years since the eraserattached itself to the pencil. We can only assume that hymen-lipmanwas a man who made his fair share of mistakes, but they may have inspired him to stick the eraser on the end of the pencil, making it more convenient to erase the written errors. He got a patent for the development on this date in 1858. Lipman's early version was a pencil with a groove at the top, into which he glued an eraser. He sold his patent in 1862; the US Supreme Court later invalidated it, saying that since combining a pencil with an eraser did not change the function of either item, the pencil-with-eraser could not be patented.
