A lie detector’s correct name is the Polygram. In 1730 a B
ritish Novelist, known as Daniel Defoe first introduced the theory of taking pulse to determine the truth. Slide3
Further on in human development,
Cesare Lonbroso created an instrument to measure blood pressure patterns in 1885. This modified
Defeo’s
theory and was the start of a brilliant discovery.Slide4
Finally, in 1902 James Mackenzie created a fully functional machine that was later named Polygram.Slide5
Additional parts were added to advance this invention over years. In 1904, another man added the ability to measure breathing. Slide6
In 1917 the polygram was put to use for the first time. Slide7
Over the years the Polygram was useless. People were able to cheat over the detectors, training their body not to react during the procedures.
