NYPD Deputy Commissioner Joseph A. Faurot begins using French police officer Alphonse Bertillon’s fingerprint system to identify suspected criminals. The use of prints for contractual endorsement (as opposed to signatures) had begun in India thirty years earlier, and print usage for police work had been adopted in India, France, Argentina and other countries by 1900, but NYPD usage represented the beginning of complete acceptance of the process in America. To date, of the billions of fingerprints taken, no two have ever been found to be identical.
