Born Today: Elizabeth Holloway Marston, Inventor of Early Polygraph Test, Inspiration for Wonder Woman (February 20, 1893-March 27, 1993)
Elizabeth Holloway earned her B.A. in psychology from Mount Holyoke in 1915. She peddled cookbooks to ladies’ clubs to raise the $100 she needed to pay for her tuition to BU School of Law, marrying William Marston before earning her LL.B in 1918. She and William worked together on researching the correlation between blood pressure and deception, developing the systolic blood-pressure test (pictured above), a precursor to the polygraph.
William Marston decided to create a comic book character who was victorious through love rather than violence, and it was Elizabeth who told him his hero had better be a woman. Her Lasso of Truth is based on Marston’s systolic blood-pressure test.
