Did You Know?

Stanford physicist Fernando Sanford may have discovered the X-ray prior to German physicist Wilhelm Roentgen, who was credited with its discovery in 1895. In an 1894 article entitled "Some Experiments in Electric Photography" published in the Physical Review (V. 11; No. 4), Dr. Sanford described an experiment from 1891 in which he developed "a negative image upon a piece of bromide paper" as well as his method for photographing a coin. He described this later experiment in more detail in an article published in the San Francisco Chronicle on December 31, 1893, entitled "Without Lens or Light." For more information, please see the Stanford Alumni Review from October 1948, pages 10-11, and May 1949, pages 14-15.
