The Wikipedia is currently telling us that the authors of the journal paper that first described "hyperthymestic syndrome" are Elizabeth Parker, Larry Cahill, Dr. Paul Tejera, and James McGaugh. That's a funny thing. Dr Paul Tejera appears to have snuck in there some time since I last looked at this Wikipedia article, because his name is new to me. And just take a look at the journal paper itself, or the PubMed record for it, and look! - no Paul Tejera! I suspect that Dr Paul Tejera's moment of Wikipedia fame as a big time memory researcher might not last very long.
