Who developed the system of anthropometry?

The correct answer is Alphonse Bertillon, who developed the system of anthropometry in the late 19th century. This system involved measuring various parts of the human body to create a unique identification profile for individuals, which was particularly useful in criminal investigations to distinguish between suspected individuals. Bertillon's method was groundbreaking for its time and represented one of the first systematic approaches to personal identification in law enforcement.

His work laid the groundwork for more advanced identification techniques, such as fingerprinting. While Hans Gross contributed significantly to forensic science and criminal investigations, and Edward Henry developed the fingerprint classification system, it was Bertillon who pioneered the use of physical measurements in identifying individuals. Arthur Conan Doyle, though influential in popularizing forensic science through his fictional detective Sherlock Holmes, did not develop scientific methods himself.
