Documents Flashcards Grammar checker. The Bertillon Anthropometric System advertisement. Introduction to Forensics Lab: The Bertillon Anthropometric System Introduction: Alphonse Bertillon invented “anthropometrics”, a method with which to identify people based upon their individual measurements.

His theory was that each person is highly individual. Therefore no one else would possess another person’s exact measurements. This system was initially accepted and used by various law enforcement agencies throughout the United States. Bertillon cards were printed reflecting these measurements, and oddly enough, a fingerprint. Bertillon chose the following parts of the body for the his measurements: Body height Outstretched reach of both arms Trunk height Width of the head Length of the head Length of the right ear Width of the right ear Length of the left foot Length of the left middle finger Length of the left little finger Length of the left forearm The choice between using the left or right sides was entirely arbitrary.

Lab: The Bertillon Anthropometric System

Although the theory suggested that it would succeed, there berhillon instances where it would fail. Anthropometrics relied upon the recorder being exact in his measurements. If the recorder was tired or inattentive, the measurements could fail to identify a person. Suspects who were drunk, ill, or uncooperative would also result in inaccurate measurements.

During his in-processing, the records clerk obtained Will West’s Bertillon measurements and photograph. Will West denied ever being incarcerated at the facility.

The records clerk doubted this information, and referenced his Bertillon measurements into the system, retrieving the Bertillon card for bertillkn William West.

Will West continued to deny that the William West card was his. Subsequent investigation disclosed that William West was already incarcerated in the facility as of September 9, By examining the photographs, one can see the failure of the Bertillon system.

Compare the Bertillon measurements in particular, keeping in mind the various factors that would affect the measurements. This failure strengthened the science of fingerprints as the normally accepted method of personal identification.

Recent opinions suggest that Will and William Berti,lon were related, therefore the closeness in measurements. Will West’s Bertillon Measurements In this activity, you will work with a partner to take Bertillon measurements for yourself. Complete the following chart below.

The case of Will West destroyed confidence in the Bertillon System literally overnight. West was arrested in and taken to Leavenworth Penitentiary. His Bertillon measurements were taken and it was found that he’d served a previous term there.

West denied that, despite the fact that his measurements “proved” that he’d done so. He was also identified visually by people who recognized him from his earlier term.

The prison officials pulled the earlier record and compared West to the photograph that had been taken earlier. They had no doubt that he was the same man. Even the name was the same. He’d served his bertilloon sentence under the name William West and was now using the name Will West. Everyone was completely convinced that Will West was indeed the same man as William West. Until, that is, the guard turned over William West’s record card and noticed that William West was still a prisoner at Leavenworth.

William West was quickly produced, and everyone marveled at the similarities. Standing side by side, the two men appeared to be identical twins, although it was later established that they were unrelated.

The prison bretillon carefully repeated the Bertillon measurements on both men, and they were found to be identical within the error regarded as acceptable for the system. Although many police departments and prisons continued to use Bertillon measurements, exclusively or supplementally, for some years, the Will West case effectively doomed the Bertillon System.

What do feet reveal about a person’s height? Forensic anthropologists team up with law enforcers to help solve crimes.

Bertillon System of Criminal Identification

Bones of the feet can reveal an interesting fact about an individual. Let’s combine math with forensics to see how.
