PBS’s documentary The Poisoner’s Handbook traces the history of how forensic science was introduced into the courtroom. The film focuses on the pioneering work of two doctors—Charles Norris and Alexander Gettler. In 1918, Charles Norris became New York City’s first Chief Medical Examiner and he created the first toxicology lab in the country. Toxicologist Alexander Gettler headed that lab. For the first time science was introduced into the criminal justice system to help solve crimes.
