Answer: Wonder Woman
William Moulton Marston was quite a Renaissance man. The trained Harvard psychologist was also inventor and writer. While many people, especially in the comic community, remembered him most in the 1940s for his creation of Wonder Woman, one of his lesser-known contributions was an invention that served as the basis for modern polygraphs.
In addition to his achievements in the field of psychology and as a comic author, Marston studied the use of systolic blood pressure as part of the lie detection analysis. After hearing his wife tell how her blood pressure had increased when she was angry or upset, he began to explore the idea of using blood pressure to analyze emotional states, and finally examined physiological reactions to deceitful language. John Augustus Larson would use Marston's systolic blood pressure monitor as part of the multi-lane modern polygraph invented by him.
Marston's research would appear in his later comic book. Just as a band around the chest revealed to its subjects whether they were lying or not, Wonder Losses's Woman of Truth also linked suspects and helped reveal their delusions.
