1 ene 1892 año - In 1892, Francis Galton popularized a method for classifying fingerprints.

Descripción:

This method is still used today. He conducted research to see the likelihood of two people having the same exact set of fingerprints, coming up with three main categories of patterns. These categories consist of the arch, the loop, and the whorl. Galton then went on to categorize them in more depth.
