Fidelus
Fidelus was first to practice forensic medicine in Italy -
First High-powered microscope*
Anton Van Leeuwenhoek constructed the first high-powered microscope. Leeuwenhoek was known to have made over 500 microscopes. In design, all Leeuwenhoek microscopes are known to have simply been powerful magnifying glasses put together. -
Identification based on teeth
Paul Revere identified the body of General Joseph Warren based on the false teeth he made for him. -
Evidence incriminating John Toms
John Toms convicted of murder on basis of torn edge of wad of paper in pistol, matching a piece of paper in his pocket. -
Spectroscopy
Gustav Kirchhoff and Robert Bunsen developed the science of Spectroscopy. -
Crime scene photography
Crime scene photography developed -
Identification using body measurements
Alphonse Bertillon developed a system to identify people using particular body measurements. -
Fingerprint identification system*
Edward Henry developed first classification system for fingerprint identification. Henry studied extensively how fingerprints could be used to identify criminals. The system he developed allowed fingerprints to be filed, searched, and traced against thousands of other fingerprints. -
Human blood groups
Karl Landsteiner identified human blood groups. -
Locard's Principle*
Edmond Locard formulated his famous principle, "Every contact leaves a trace."
"It is impossible for a criminal to act, especially considering the intensity of a crime, without leaving traces of his presence." -Edmond Locard
Locard got to test out his principle during many investigations. One particular one was of a Frenchwoman named Marie Latelle who had been found dead (1912). -
Mass Spectrometer
Francis Aston developed the mass spectrometer. -
DNA double helix*
James Watson and Francis Crick discover the DNA double helix.
"This structure has novel features which are of considerable biological interest." - James Watson and Francis Crick
Watson and Crick used stick-and-ball models to test out their ideas on the possible structure of DNA, unlike other scientists who used experimental methods. -
AFIS
AFIS developed by FBI, fully automated in 1966. -
First DNA tests developed
Jeffreys developed and used first DNA tests to be applied to a criminal case.
