  1. History of Forensics: a TIMELINE

  2. Early Discoveries • In 250 B.C. Erasistratus noticed that his patient’s pulse would increase when they were telling a lie.

  3. 1800’s • In 1828, William Nichol invented the polarizing light microscope. • In 1837, Walter Specht developed luminol.

  4. 1879, Bertillon’s Anthropometry comes on the scene.

  5. 1903 – The William West – Will West Case at a Federal Prison in Leavenworth, Kansas, changed the way that people were classified and identified. Anthropometry out … fingerprints in.

  10. TIME LINE ASSIGNMENT 1. Groups of 32. Assemble 6 events or discoveries, on 6 pages, taped together short end to short end.3. Indicate year at top; invention/discovery at bottom… like this: 1879 (DRAWING) Anthropometry
