X-Ray Tube


Cold cathode bi-anode x-ray tube with leaded glass windows for x-ray emission. The form was designed by Henry Grainger Piffard (1842-1910), a dermatologist who taught at New York University, and the first American to use x-rays to treat skin diseases. Piffard called it a "safety" tube because it had thick glass lead glass walls that would reduce exposure to the operator. This example, now discolored from use, was probably made by E. Machlett & Son, of New York City.
