March 30, 1858: H. L. Lipman, of Philadelphia, patented the first pencil with eraser

In 1858, an American inventor named Hyman Lipman patented the design for a pencil with an attached eraser. His invention involved attaching a small rubber eraser to the end of a wooden pencil, creating a convenient two-in-one writing and erasing tool. This innovation made pencils more practical and popular, as it eliminated the need to carry a separate eraser.
