Francis Henry Galton’s contribution was the one that published “Fingerprints,” a book that has helped lead us to the use of fingerprinting for identification. This book was published in 1892. The use of fingerprinting has helped the forensics world a lot with finding those who have committed a crime or even the victim, if unknown. “The Father of Forensic Toxicology,” is Mathieu Orfila. Mathieu was the man who published the detection of poisons and their effects on animals in 1814.
This is now used to help determine if poisons were involved in a homicide or rape. Although Hans Gross made a lot of contributions to forensic science there are two that changed it for the better. First in 1893, he wrote the first scientific document describing the disciplines for a criminal investigation. Today they are used in all criminal investigations. He later wrote a journal, which would show experts of criminal investigation, how all different fields that with combined expertise would improve the detection of crime.
These different fields would include Microscopy, fingerprinting, anthropometry, botany, zoology, mineralogy, physics, and chemistry. Dr. Karl Landsteiner and Dr. Leone Lattes were in the blood detection. By putting efforts of ones work with the other, Dr. Lattes put his technique, and Dr. Landsteiner’s blood type findings together and he applied it to criminal investigations. Edmond Locard was the first one to pursue the working forensics lab and put the principles into play.
He developed what we call Locards Exchange Principle, which shows that when materials are exchanged when two objects come in contact with one another. Dr. Walter C. McCrone brought the Microscope to forensic science in the twentieth century. He taught thousands of forensic scientists about the techniques of microscopy. Saferstein, R. (2009).
