Publicity photo of Nikola Tesla sitting in his laboratory in Colorado Springs in December 1899. Photo was taken by Dickenson V. Alley, photographer at the Century Magazines. The laboratory was built in 1899. Tesla sent a copy of this photograph to Sir William Crookes in England in 1901.
This image is a Multiple exposure. The photo is cited as a double exposure by Carl Willis and Marc Seifer. Tesla's Colorado Springs notes identify the photo as a double exposure. To give an idea of the magnitude of the discharge the experimenter is sitting slightly behind the "extra coil". I did not like this idea but some people find such photographs interesting. Of course, the discharge was not playing when the experimenter was photographed, as might be imagined!
Conversely a copy of the original photograph was collected by Leland I. Anderson who sold the collection to Tesla Wardenclyffe Project. They now claim copyright. Note that the version in that archive includes a hand written note added in 1901 printing which doesn't appear on the more widely available image.
This image (or other media file) is in the public domain because its copyright has expired. This applies to the United States, where Works published prior to 1978 were copyright protected for a maximum of 75 years. See Circular 1 "COPYRIGHT BASICS" PDF. Works published before 1923, in this case 1899, are now in the public domain. +sookie tex
