On today's date, in 1858, Hymen Lipman received a patent for the pencil. Lipmen was granted the patent for attaching a rubber eraser at one end. The patent was later revoked however, when the Supreme Court ruled in 1875 that a pencil with an eraser is not a groundbreaking invention. Evidently the Supremes never made any mistakes. So it goes.
No word on when the pencil box was invented.
