The famous American inventor Thomas Alva Edison could never have imagined the turn of his invention when he patented his electric pen in 1876. The pen was intended as an aid for copying handwritten texts.
O'Reilly, however, saw completely different possibilities for Edison's invention. O'Reilly, a well-known, enterprising tattoo artist, visited a store that sold Edison's pen and attended a demonstration.
It gave him an idea, InventHelp Prototype and so in 1891 he applied for a patent for the world's first electric tattoo machine - based on the technology of the electric pen.
The new machine revolutionized the tattoo industry and soon replaced the old, traditional methods, where a tattoo was made by manually scratching and pricking ink on the skin.
