A publicity photo taken in 1899 at Nikola Tesla’s laboratory in Colorado Springs, Colorado, where the inventor worked before he established his Wardenclyffe laboratory on Long Island. The photo was a double exposure — his pose and the sparks recorded at different times — helping him avoid electrocution. The “magnifying transmitter” pictured here was said to produce millions of volts of electricity.
