Rudolph (Rudolfo) Schuller (1873-1932) was a linguist with a special interest in the languages of Central and South America. He served on the faculty of the National University in Mexico City.
Schuller along with Charles Schucert was invited by the American Geographical Society to present a review of Pierre Termier’s paper on Atlantis. Schuller gave cautious support for a possible American Atlantis, but also noted “The fact that the narrative of the island’s submersion has been regarded by most scholars as a “fabled tale” proves little or nothing.”
However, Schucert was more sceptical(a). Their comments were published in Geographical Review (Vol. 3, No. 1 (Jan., 1917), pp. 61-66) and more recently on Jason Colavito’s website(b).
