To be fair they are named in the link
Dr. Roy Knutsen "Emeritus Bible Professor" at Northwestern College - apparently a small private Bible college in St. Paul.
Dr. B Michael Blaine "Archaeologist/Curator The Near East Museum" - which "The Near East Musueum" is not said, but his comments seem at odds with what I've read. (Finkelstein argues quite convincingly that the placenames best fit the situation of the 11th Century). I'd ask Brian to look it over but it seems clear to me that he is arguing as a religious apologist rather than an unbiased expert (calling Exodus "an eyewitness account" is rather a giveaway).
Dr Bryant Wood - another apologist. Again, I'd ask Brian but his reports from Jericho have come in for heavy criticism.
Dr. Robert Siblerud an Environmental Physiologist and apparently a real crank. He was co-founder of this defunct organisation

Just read the description of this book:

quote:
It begins with the most ancient of civilizations, Lemuria, the lost continent in the Pacific, and explains why the ancients called it the mother of civilizations.
But not only is he not credible he doesn't actually say anything worth considering. All he does is repeat what someone else wrote - and there's an editorial comment to the effect that what he says is wrong.
So why count him ? I guess Lysimachus was relying on nobody following it up - or, as usual he didn't bother to read it properly.
