1628 Marcello Malpighi noticed that there are patterns on the skin. This event is significant because today we can identify suspects by using fingerprints. (No two people have the same fingerprints.)
1732 Luigi Galvani discovered that the human nervous system transmits information electronically. This is important in modern forensics because we use his theory to make lie detectors. These lie detectors help detectives acquire important information.
1836 This date is significant because John Marsh discovered a chemical solution that reacts to arsenic. This is important to modern forensics because we can use this method in order to find a possible cause of death.
1888 This year is significant because Chicago is the first to adopt the Bertillon system of identification. This is important to modern forensics because we now identify people by their faces and use them to document criminals.
1900 This date is significant because Karl Landsteiner discovered blood types. This is important to modern forensics because one method to identify and differentiate people (suspects) is through blood types .
1905 This year is significant because President Roosevelt established the FBI. It is important to modern forensics because the FBI works undercover to protect Americans and capture criminals and terrorists.
1920s This year is significant because Luke May did analysis of tool marks. It is important to modern forensics because we can now discover cause of death and how the victim died by looking at marks made on the victim's body.
1921 This year is significant because John Larson built the first lie detector. It is important to modern forensics because we use this device to acquire important information pertaining to the case. (And discover what info is true and false.)
1932 This year is significant because it was when the first FBI crime laboratory was created. This is important to modern forensics because we use these facilities to study different aspects of the cases presented.
1957 This year is significant because it was when the growth stages of skeletal bones were discovered by Thomas Marker and Thomas Stewart. This is important to modern forensics because we can now determine to age of the victim by observing what stage the bone is in.
