Which major innovation in forensic science was pioneered by Dr. Leon Latts?

Dr. Leon Latts is recognized for his contributions to serology, which is the study of blood and other bodily fluids as they pertain to forensic science. His work significantly advanced the methods used to analyze bloodstains and other biological samples found at crime scenes. Serology is crucial because it allows investigators to determine the presence of bodily fluids and to link them to individuals through testing for blood types or other markers. This was a formative development in the field of forensic science, enhancing the ability to establish connections between suspects and crime scenes before the advent of more advanced techniques like DNA analysis.

In contrast, DNA analysis, ballistics, and fingerprinting were advanced by other notable figures and have their own distinct histories. Each of these methods plays a vital role in forensic investigations, but Dr. Latts's specific contributions positioned serology as an essential tool for experts in the field of criminal forensics.
