I was recently told, by an aquaintance of mine, that her grandfather was in the Smithsonian for being a quack. Of course the family thinks the guy was a genius, and that the Smithsonian is wrong... I am curious about what this guy could have invented. I haven't had any luck with the google in finding any info on who or what they have in their collection of quakery. Does anyone know of any sites with listings of quack devices and their inventors?
