This is a historic black and white photograph of Nikola Tesla conducting an experiment in his laboratory. The image is dominated by a dramatic display of electrical discharge, with bright sparks and arcs of electricity emanating from a large metal cylinder on the right. Tesla is seated on a chair to the left, observing the experiment with a calm demeanor. The laboratory has wooden walls and a simple, functional design. Wires and other electrical equipment are visible throughout the space. The photograph captures a moment of scientific discovery and innovation, showcasing Tesla's pioneering work in the field of electricity. There is handwritten text at the bottom of the image, presumably written by Tesla himself.
