History of Hair/Fiber Analysis

French scientist Edmond Locard discovered that people constantly pick up and transfer bits of dust, hair, fibers and other "trace" material without being conscious of it. Locard realized that these material exchanges were key to analyzing a crime scene, and the "Locard Exchange Principle" became the foundation of forensic science in the early 1900s.

German pathologist Rudolf Virchow later showed that hairs were not unique enough to positively match a particular suspect to a particular victim.

In the United States, Paul L. Kirk established the fundamentals of microscopic hair analysis used by scientists today, and his groundbreaking textbook, "Crime Investigation," is still an important text in criminal investigation.

  1. Your blog has a lot of good info about the histroy of hair and fiber and the pictures only make it better. Though the info is good, i really doubt that is all the history on hair and fiber, more of a scratch on the surface. All you need to do is add more info and it will be great
