I got suprise. The basic tattoo machine was invented by Thomas Edison. He made autographic printer, which was intended as an engraving device. Later, Samuel O'Reilly found Edison's machine could be modified to introduce ink into skin, and patented the tube and needle system, which is still in use today.
