Harold von Braunhut was an American mail-order marketer and inventor, most famous as the creator and seller of both the Amazing Sea-Monkeys and the X-Ray Specs.
Despite his Jewish ethnicity, Braunhut had a close association with white supremacist groups, buying firearms for a Ku Klux Klan faction and regularly attending the Aryan Nations annual conference. He added "von" to his name some time in the 1950s for a more Germanic sound and so he could be more distant from his Jewish family.
