Early Skiagraph Photographic Half tone Print X Rays Roentgen Ray Images Equipment 1900. 12" x 8. 1/2"
A scarce early half tone print showing the equipment used for working X rays or Roentgen rays, the means of taking Skiagraphs (photographs) of the rays and also two images of early X rays. The large picture in the top half of the print shows the general set up for the X ray apparatus, each component is labeled and the key at the bottom of the print details what the part is for. The picture to the bottom right shows the arrangement for making Skiagraphs with the rays, again the pieces are detailed at the bottom of the print. The two pictures to the bottom left are respectively the leg and head of a pigeon. ( A Skiagraph is a permanent shadow picture produced by Roentgen rays passing through the object and falling upon photographic film).
Print published by Funk and Wagnall in the subscribers edition of their Standard Dictionary of the English Language in 1900. As Wilhelm Roentgen didn't make his discovery of X Rays until November 1895 the print offered for sale here can be classed as a very early published example and is one of two I am listing. Of interest to collectors of medical science, photographic prints or just the unusual.
