I think some bloke had a few ideas about human pedigrees in the 1930s; Germany I think it was. Something about an Aryan super race and "lebensraum" for them to live in? Sounded quite idealistic and utopian really, but it got quite embarrassing when he saw how fast black guys could run (and I suspect he had a sneaking admiration for the way yellow guys could overrun, too). Same bloke had some really neat ideas on the registration of guns, too. Philospher of sorts - Albert Hiller? His name escapes me for the moment...
