Vucetich's Dactilonomo, about 1891. The original Dactilonomo invented by Vucetich for demonstrating diverse fingerprint combinations in his classification method. Juan Vucetich (1858-1925) was a Croatian-born Argentine anthropologist and police official who pioneered the use of fingerprinting. In 1891 Vucetich began the first filing of fingerprints based on ideas of Francis Galton which he expanded significantly. He became the director of the Center for Dactyloscopy in Buenos Aires. Argentine police adopted Vucetich's method of fingerprinting classification and it spread to police forces all over the world.
