I do not think that Kuiper believed in a belt of comets out as far as 100 AU, generally just beyond Neptune, today it ends at about 42 AU where QB1 is, but more Important you have failed to list a more important name, Kenneth Edgeworth, a European who predicted that a band of comets would lie much farther out. These have been found and are the SDOs, Scattered Disc Orbs. I am Dr. Wm. Greig, retired Consilienst, and i know more about where these things should be than anyone. I hope this gets to ms.
