Alphonse Bertillon

Every measurement slowly reveals the workings of the criminal. Careful observation and patience will reveal the truth.

Alphonse Bertillon (April 24, 1853-February 13, 1914) was a French law enforcement officer and biometrics researcher who created anthropometry, an identification system based on physical measurements. Anthropometry was the first scientific system police used to identify criminals. Until this time, criminals could only be identified based on eyewitness accounts, which are known to be unreliable. The method was eventually supplanted by fingerprinting, but "his other contributions like the mug shot and the systematisation of crime-scene photography remain in place to this day.".
