opened the door for the study of fingerprints. Bertillion used fingerprints in his system but didn’t have a good way to organize them for mass searches. Dr. Juan Vucetich conceived of a method of fingerprint classification in 1894 that provided for 1‚048‚576 primary classifications of fingerprints. His work was largely unheard of in Europe until Sir Edward Henry devised a fingerprint classification system‚ still used today to categorize sets of fingerprints and store them for easy
