That was no someone. That was Nathaniel Kleitman, the father of modern sleep research, renowned for his classic text _Sleep and Wakefulness_ (1939). It was in his laboratory that Aserinsky first observed rapid eye movement sleep. Kleitman and a colleague became famous for their Mammoth cave study, documented in a Scientific American article which was assigned to generations of psychology students. As I recall, Kleitman found that he couldn't adapt to one of the artificial sleep-wake cycles they tried out, and was miserable throughout their stay; His colleague managed just fine. http://tinyurl.com/25z9kz5 for the cave study www.architalbiol.org/index.php/aib/article/download/200/179 for William Dement's affectionate remembrance of the great man.
