Early X-ray demonstration. Lithograph and X-ray (gelatin silver print) montage from 1896, showing two views of a woman. At left, she is clothed, with the presence of X-rays marked by the letter X. At right, the X-rays have imaged her skeleton. X-rays, discovered in 1895 by German physicist Wilhelm Conrad Roentgen (1845-1923), and initially reported in the mainstream press, became an instant sensation. The German inscription at left translates as 'A new light moves the world'. The stamp at lower right references the Philadelphia, Pennsylvania, USA, branch of the IOOF fraternity, the Independent Order of Odd Fellows.
