Tattoo guns are better known as tattoo machines because they are used to create tattoos. The first prototype of this machine was made by Thomas Edison, the famous inventor of light bulb. The machine however, was not intended to create tattoos but rather as a sort of design transfer mechanism or as an engraving machine. This idea was later copied and modified so that sometime in the 1890s, another person thought of revising Edison's machine and incorporated an ink chamber. The presence of the ink chamber enables the machine to let ink into the skin which gave way to the invention of the first ever tattoo gun.
