Dr. William Moulton Marston (1893-1947) a harvard grad who was lucky enough to live in a polyamouous relationship, was the inventor of what was one of the first polygraph machines around 1918. But what is interesting, is that the two women in his life helped inspire him to create the comic book icon...Wonder Woman and her "magic lasso"...which of course...when wrapped around people made them tell the truth about anything...........i heard it on NPR Saturday morning...........oompa
