Final answer:
William Marston invented both the lie-detector technology and the comic book hero Wonder Woman, reflecting his expertise in psychology and his belief in gender equality.
Step-by-step explanation:
William Marston, a psychologist by training, is credited with two notable inventions from very different realms. Not only did he contribute to the development of lie-detector technology, but he is also the creator of the iconic comic book hero, Wonder Woman. Marston's contribution to the polygraph relied on the use of blood pressure measurements to detect lies, underlining his interest in human psychology.
In stark contrast to this scientific endeavor, Marston created Wonder Woman in 1941, with the intent to inspire women and represent a model of peace, justice, and gender equality—themes that were informed by his personal and professional beliefs about the potential of women in society.
