Díaz Romero, Belisario
Belisario Díaz Romero (1870-1940) was a Bolivian businessman and polymath from La Paz. He had some ideas regarding race and evolution(a). that today would be considered odd, if not offensive. He believed that Tiwanaku had been built by a race of people he calls Homo atlanticus, who had come to America from Atlantis, situated in the Atlantic, over a landbridge from the east, over two hundred million years ago!

His 1906 book Tiahuanacu is now freely available online(b).
