  In 1894 Fernando Sanford discussed in a paper published by the Physical
Review an electric photography technique, which he developed starting from
1891. The images that he published in the paper are clearly showing some
fringes about the objects he photographed. Several years after, the fringes
appearing in the electric photography have been recognized as the "Kirlian
effect". Unlike Kirlian, Sanford did his best to reduce these fringes,
improving the device but losing the "Sanford effect".
