By GEORGE C. HENDERSON

THESE cryptic signs, sent together with a fingerprint photo by the telephotographic process through 2,500 miles of space over mountains and desert in a few minutes’ time, constituted a challenge from the New York police to the San Francisco police to answer one question—’”Who is the man?

Police Identification System “Fingerprints” Faces (Oct, 1941)

Police Identification System “Fingerprints” Faces

FACES are classified like fingerprints, to index hundreds of thousands of portraits, in the criminal files of Los Angeles County, Calif. A ruled glass screen called a “physiogmograph,” applied to each photograph, enables experts to determine accurately such information as facial height and width, and the size and shape of nose and mouth. Characteristics also noted include position of the ears, height, weight, general build, and the color of hair, eyes, and complexion. Finally, all these items are ingeniously combined in a number-and-letter code symbol, such as 11/5 NUFCFLCHD, under which the picture is filed.
