Did you know? 
     Perhaps the most famous individual to exhibit hypermnesia 
was a Russian man known as "S," whose amazing photographic 
memory was studied for 30 years by a psychologist in the early 
part of the 20th century. "Hypermnesia" sometimes refers to 
cases like that of "S," but it can also refer to specific 
instances of heightened memory (such as those brought on by 
trauma or hypnosis) experienced by people whose memory abilities 
are unremarkable under ordinary circumstances. The 
word "hypermnesia," which has been with us since at least 1882, 
was created in New Latin as the combination of "hyper-" 
(meaning "beyond" or "super") and "-mnesia" (patterned 
after "amnesia"). It ultimately derives from the Greek 
word "mnasthai," meaning "to remember."
