1 FORENSICS: THE APPLICATION OF SCIENTIFIC KNOWLEDGE TO LEGAL PROBLEMS, ESPECIALLY THE SCIENTIFIC ANALYSIS OF PHYSICAL EVIDENCE. (WEBSTER’S DICTIONARY) The History of Forensics

2 Forensic Science Timeline Pre-historic picture writing of a hand with ridge patterns is discovered in Nova Scotia. In ancient Babylon, fingerprints were used on clay tablets for business transactions. 700 BC-Thumb prints were found in clay seals in ancient China. 250 BC-Erasistratus, an ancient Greek physician, observes his patients’ pulse rates increase when they tell him lies. 44 BC-Antistius, an ancient Roman physician, examines the body of Julius Caesar after his assassination and finds more than 23 stab wounds.

5 1863-C.F. Schonbein discovers the ability of hemoglobin to oxidize in H 2 O 2 making it foam. This is the first presumptive test for blood. 1865-Taylor and Wilkes write a paper on determination of time since death from the fall in body temperature. 1901-K. Landsteiner first discovers human blood groups. M. Richter adapts the technique to type blood stains. 1902-R. Fischer describes the furrows on human lips; a fact that later formed the basis for cheiloscopy (lip print ID)

6 1903-The first forensic science curriculum is developed at the University of Lausanne, in Switzerland. 1905-President T. Roosevelt establishes the FBI. 1908-George Popp firmly established forensic geology as a means to find the murderer of a Bavarian woman. 1910-A.S. Osborne publishes Questioned Documents on document forgery in America. 1924-A. Vollmer, police chief in Los Angeles, implements the first U.S. police crime laboratory.

7 1933-T. Gonzales of Mexico City Police Headquarters, introduces the diphenyl-amine test in the U.S. to detect gunshot residues. 1937-W. Specht develops the chemiluminescent reagent luminol as a presumptive test for blood. 1950-M. Frei-Sulzer develops the tape lifting method of collecting trace evidence. 1974-Aerospace Corp. scientists develop the technology to analyze GSR using SEM with electron dispersice X-rays 1977-M. Soba develops the technique for lifting latent fingerprints using Superglue fuming

8 1985-Police in the UK first use forensic DNA profiling 1998-The FBI sets up that National DNA Index System, enabling city, county, state, and federal law enforcement agencies to compare DNA profiles 1999-The FBI implements the Integrated Automated Fingerprint Identification System, allowing paperless submission, storage, and search of the national database.
