For most of human history, sudden and unexpected deaths of a suspicious nature, when they were investigated at all, were examined by lay persons without any formal training. People often got away with murder. That is, until Frances Glessner Lee. Frances Glessner Lee (1878-1962), born a socialite to a wealthy and influential Chicago family, was never meant to have a career, let alone one steeped in death and depravity. Yet she became the mother of modern forensics and was instrumental in elevating homicide investigation to a scientific discipline. Frances learned forensic science under the tutelage of pioneering medical examiner Magrath. A voracious reader too, Lee acquired and read books on criminology and forensic science - eventually establishing the largest library of legal medicine.
