This Weegy thread provides a clear and informative summary of pivotal figures in the development of forensic science. Cesare Beccaria's emphasis on fair trials and proportionate punishment was revolutionary in shaping modern criminal law, promoting the idea that justice should be rational and evidence-based. Edmond Locard, often called the “Sherlock Holmes of Lyon,” made a lasting impact with his Locard Exchange Principle—reminding us that no crime scene interaction is ever completely trace-free. Together, their contributions form the backbone of forensic investigation and criminal justice systems today. Thanks for sharing such valuable knowledge in a simple and accessible way!
