(Fingerprints). In a book written by Sung Tz'u called The Washing Away of Wrong, the author observed that water collected in the lungs of drowning victims and that strangulation could be assumed by damaged cartilage in the neck. (Blood), Christian Friedrich Schönbein was the first to discover the ability of hemoglobin to oxidize hydrogen peroxide making it foam. (Fingerprints), Paul Jesrich, who was a former chemist, took photomicrographs of two bullets to compare the minutiae. A few years later, a doctor "experimenting" with the corpses of dead soldiers in Malta discovered that body temperature dropped at regular intervals following death, and could be used to determine time of death. By the beginning of the 19th century, the study of hairs, fingerprints and blood thrust the development of forensic investigation to new heights. Across the miles, another Briton living in Japan had come to the same conclusion. That same year, it seemed as if everyone was in on the debate on whether or not to allow DNA evidence into an American case which resulted in the process to certify and standardize forensic-related quality control guidelines throughout the United States and the world. By the early 1900s, the field of forensic investigation achieved major developments, due to the design and use of modern forensic methods and discoveries such as Benzidine, a chemical compound used to develop a universal, presumptive test for blood. He is also considered the father of modern toxicology. In ancient times, the manner of death was naturally assumed by where and how the victim had been found. Mathieu Bonaventure made significant contributionsto development of tests for the presence of blood in a forensics context. By 1930, an American Criminalist named Luke May had developed tool mark striation analysis and observations and published in the American Journal of Police Science an article discussing the importance of discerning identification and differences in knives, tools and other instruments.

(Ballistics), William Herschel used fingerprints as a way to make natives sign a contract. La capacitación existió siempre: cronología. (Blood), Brian J. Culliford initiates development of gel-based methods to test for Isoenzymes in dried bloodstains. He helped develop tests for the presence of blood in forensic context. Henry Faulds was curious whether or not fingerprints remained the same despite efforts made to erase such fingerprints. Advancements in research of DNA profiling and blood analysis perfected methods such as RFLP (restriction fragment length polymorphism) and PCR (polymerase chain reaction) testing made it possible to identify victims as well as suspects in a process commonly known as DNA Fingerprinting, the most famous of forensic discoveries of the 20. He experimented with volunteers, introducing pumice stone, sandpaper and even acids to determine if fingerprints would appear different after new skin growth. Before the discovery and impact of DNA in the early 1980s, the advent of fingerprinting in the early 1800s and even before photographs were used in the late 1800s to capture images of killers on a victim's eyeballs, as was the case during the investigation of the world's first documented serial killer, Jack the Ripper, criminal investigators were using the science of forensics to solve crimes.
