In 1891, Samuel O'Reilly of New York patented the first electric tattoo machine, adapted from Thomas Edison's electric engraving pen. The device used electromagnetic coils to drive needles rapidly into the skin, dramatically reducing the time and pain involved in tattooing and making detailed, consistent designs far more achievable. This invention democratised tattooing by making it faster, cheaper, and accessible to a much wider clientele, transforming it from a specialist craft of the few into a mass-market practice.

The electric tattoo machine's democratisation of body inscription contributed to the broader late-Victorian and Edwardian fascination with the decorated working-class and criminal body that appears in the naturalist literature of the period — Zola's tattooed labourers, Kipling's soldiers, and the marked bodies of Jack London's fiction. The machine-mediated tattoo raised questions about authenticity, pain, and the mass production of personal identity that anticipate modernist poetry's anxieties about mechanical reproduction and the mass-produced self. These concerns resurface in twentieth-century poetic treatments of the branded or marked body.
