Eye print

In 1935, the use of eye prints - the pattern of capillaries in the retina - was described in an article in Time magazine as a new scientific method for identification because an individual's eye pattern is as unique as fingerprints. It was promoted by Dr. Carleton Simon, a psychiatrist and criminologist, upon the suggestion of Dr. Isadore Goldstein, an ophthalmologist at Mount Sinai Hospital. The retina of the eye could be photographed straight through the pupil with a Zeiss retinal camera. Dr. Simon had been a New York City deputy police commissioner (1920-26). Simon and Goldstein published a paper on the method in the New York State Journal of Medicine, Sep 1935, Vol. 35, No. 18, pp 901-6.«
