William C. Dement. William Charles Dement (born July 29, 1928) is a pioneering US sleep researcher and founder of the Sleep Research Center at Stanford University. He is a leading authority on sleep, sleep deprivation and the diagnosis and treatment of sleep disorders such as sleep apnea and narcolepsy.
William was the son of the unmarried Robert I, Duke of Normandy, by Robert's mistress Herleva. His illegitimate status and his youth caused some difficulties for him after he succeeded his father, as did the anarchy that plagued the first years of his rule.
