Transcript of Forensic Science
Brittany Galloway Historical Timeline Marcello Malpighi Early Chinese He was the founder of modern anatomy
Noted the ridges and rounds in our fingerprints
A layer of skin is named after him: "Malpighi" layer Carl Wilhelm Scheele Discovered how to change arsenious oxide into aresenious acid Valentin Ross Discovered a more precise way of finding arsenic Matheiu Orfila Father of forensic toxology
1814: Published Treatise on the detectection of poisons. William Nichol Developed the first polarizing light microscope James Marsh English Chemist
1836: developed a test for the presence of arsenic in tissues, known as the Marsh Test Alphonse Bertillon Hans Gross Dr. Karl Landsteiner Dr. Leone Lattes Albert Osborn Edmond Locard Dr. Walter McCrone Col. Calvin Goddard Sir Alec Jeffreys Frye Standard Daubert Ruling Forensic Science 700's : Discovered fingerprints
1248: "Hsi Duan Yu" a book that described how to tell drowning from strangulation Fingerprints can now be used to solve crimes and set innocent people free.
The book helped differentiate between drowning and strangulation. Helped with the idea of knowing the cause of death. 1628-1694 1742-1786 1806 1787- 1853 Helped further the knowledge of what we know now about fingerprints. No person in the world has the same fingerprint! Gave another possibilty for a cause of death, and how you can check for it. 1828 1794- 1846 "Nicol Prism" 1853- 1914 French Scientist

His microscope made deciphering evidence a lot easier. (bullets, fingerprints) 1891-1955 1916-2002 1950 Father of DNA fingerprinting
