May 2022 boasts the 101st anniversary of the polygraph machine. John Larson, the inventor, was raised in New England and later moved to Berkeley, California, where he obtained a doctorate degree in physiology with a concentration in forensic science. In 1920, he joined the Berkeley Police Department, making him the first police officer to have a terminal degree in the United States. His invention, commonly known as “the lie detector,” simultaneously measures suspects’ blood pressure, pulse, respiration, and skin variations during the interrogation process. Over 15 years, Larson used his grilling apparatus to solve hundreds of criminal cases, including murder, robbery, theft, and sex crimes. In 1922, the polygraph went into production and was soon used by law enforcement agencies throughout the United States (Alder).
