Who invented the first polygraph machine?
A machine used by law enforcement to detect when a person lied was first designed created and developed by Dr. John Augustus Larson in 1921. Larson's machine was developed to detect changes in the blood pressure, skin temperature, and breathing rate of the person being tested. This device was first used by the Berkeley Police Department.Larson's invention was later improved and perfected by his "apprentice", Leonarde Keeler. Keeler would go on to change to an ink recording system, create something less bulky and cumbersome, and an indicator to show when the question was asked.

What are facts about the first lie detector invented?
The first lie detector, known as the polygraph, was invented by John Augustus Larson in 1921. It measures physiological responses such as heart rate, blood pressure, and respiration while a subject answers questions, based on the premise that deceptive answers trigger distinct physiological changes. Larson's invention was a significant advancement from earlier devices and laid the groundwork for modern lie detection techniques. Despite its use in law enforcement and other fields, the accuracy and reliability of polygraph tests remain controversial.
