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.
