Later History
     Victor Balthazard and Marcelle Lambert (both French) co-published a scientific study on hair in 1910 based on previous research by Rudolph Virchow (a German).

     Edmond Locard set up the first forensic lab in 1910.  The French officers in charge gave him two attics and two assistants  It is believed he had to buy the microscope, and a spectrometer (machine to measure light).  Locard proved himself and was given more staff and equipment when he helped solve a difficult murder.  He even came up with his own theory that we still follow today.  Originally referred to as Locard's Exchange Principle, the Contact Trace Theory states that the criminal always left something on a scene and always took something.  By finding this "trace" of the suspect you can tell where the suspect was before.  Find a "trace" of a victim on the suspect or suspect's property without reason for the victim to have left it voluntarily, and you connect the victim to the scene.  (Trace refers to evidence, usually small and hard to see.)

     J. Edgar Hoover took over the Federal Bureau of Investigation (FBI) in 1930.  While running it, Hoover built the FBI up to its modern level of standards.  He set up the National Fingerprint File then Automated Fingerprint Identification System (AFIS).  He set up the first US forensic lab in 1932.    In 1967, Hoover set up teh National Crime Information Center (NCIC).  Both NCIC and AFIS are still in use.  The FBI continued to set up systems as the new advances allowed.  In fact, we now have Combined DNA Index System (CODIS) to track and compare DNA profiles the way that AFIS does fingerprints.  Ray White helped by detecting differences in DNA, which helped in 1987 to convict a person.  CODIS has two parts to the system, the Convicted Offender Index of solved cases and the Forensic Index of unsolved cases.  In 1998, public forensic labs set up their own system, called the National DNA Index System.  It links serial crimes by DNA matches.  Georgia was the first state to sign up for NDIS.  The last database set up by the FBI is the Drugfire in 1992.  The site allows the computer comparison of casings, bullets, and guns that are recovered from drug busts, homicides, and aggravated crimes.  Crimes can be linked automatically and nationally.

That is a course overview of the history of forensic science.  So many more great contributors exist.  You will meet some as we go to other units but it is up to you to find out more on your own if your interested.  :)
