who is known as the father of polygraph
Polygraph Despite his predecessor's contributions, Marston styled himself the "father of the polygraph." (Today he is often equally or more noted as the creator of the comic book character Wonder Woman.)[77] Marston remained the device's primary advocate, lobbying for its use in the courts. In 1938 he published a book, The Lie Detector Test, wherein he documented the theory and use of the device.[78] In 1938 he appeared in advertising by the Gillette company claiming that the polygraph showed Gillette razors were better than the competition.[79][80][81]
