Ancient China (circa 1248 AD): The washing away of wrongs by Song Ci stands as a seminal work in early forensic science. This book detailed methods for investigating death, including differentiating drowning from strangulation, and identifying weapons used in crimes. It's considered a foundational text, showcasing early attempts at systematic forensic examination. These included the use of insects to determine time of death (a precursor to modern forensic entomology), the examination of wounds to determine cause of death, and the examination of objects found at a crime scene to help determine what occurred Simple, but easy to overlook..
-
Ancient Greece and Rome: While not as systematically documented as in China, Greek and Roman physicians like Hippocrates (460-370 BC) and Galen (129-216 AD) made observations about injuries and their causes, laying some groundwork for future forensic pathology. Their observations, though limited by the scientific understanding of their era, began to establish a connection between physical evidence and criminal acts.
-
Medieval Period: The medieval period saw less systematic development, but advancements in medicine and observation continued. The increasing complexity of societies and the need to resolve disputes (and catch criminals) continued to push forward the need for further developments. Medical examiners began to contribute to the investigation of sudden or unexplained deaths.
The Dawn of Modern Forensic Science: 17th-19th Centuries
The 17th-19th centuries witnessed significant breakthroughs that laid the foundation for modern forensic science. This period saw the emergence of specific scientific disciplines and their application to criminal investigations:
-
The 17th Century: Early Microscopy and Blood Analysis: The invention and improvement of the microscope allowed for more detailed analysis of evidence. Early observations on blood and its properties started to appear, laying groundwork for future serological techniques. Though very crude, early examinations of wounds were also done and recorded.
-
The 18th Century: Toxicology Emerges: The development of analytical chemistry spurred progress in toxicology. Scientists began to develop methods for detecting poisons in bodies, a crucial development in forensic investigations. Mathieu Orfila (1787-1853) is considered the "father of toxicology" for his work in developing systematic methods for identifying poisons. This period also witnessed the refinement of fingerprint identification, which was beginning to gain traction, though it was not yet considered a main method of identification It's one of those things that adds up..
