William Charles Dement (July 29, 1928 – June 17, 2020) was an American sleep researcher and founder of the Sleep Research Center at Stanford University. He was a leading authority on sleep, sleep deprivation and the diagnosis and treatment of sleep disorders such as sleep apnea and narcolepsy. For this pioneering work in a previously uncharted field in the United States, he is sometimes referred to as the American father of sleep medicine.
