“ Marston was hired by the US government during WWI to come up with a way to make sure that prisoners of war told the truth during interrogation. Echoing Lombroso’s experiments, he decided to test his subjects’ blood pressure during their interviews. In 1917, he published his findings to great acclaim in the press, who hailed him as the inventor of the “lie detector.” Marston didn’t shy away from the title. In fact, he publicly stated that his discovery hailed “the end of man’s long, futile striving for a means of distinguishing truth-telling from deception.” Marston remained a firm advocate for the implementation of the polygraph into the court system, and was brought in to administer a lie detection test for the 1923 case of Frye vs. United States.
