From the depths of the newly available New York Times archives, May 12, 1896 at the bottom of this article (PDF) about Thomas Edison’s flouroscope exhibition at the Electrical Exposition. The exhibit allowed visitors to see an x-ray of their hands. “X Rays Aid an Operation. An interesting operation was performed yesterday at Bellevue Hospital. Patrick Lync of 303 East Thirty-first Street, during a saloon row May 4 last, was shot in the left arm. The bullet could not be located and on Saturday night last Lynch was taken by Dr. Hibbard to the electrical show where he had a cathodograph taken of the arm. The bullet was then located and was extracted yesterday.”
