Deaths: Faculty and staff

FACULTY

Nathaniel Kleitman, PhD'23, a sleep researcher and retired professor emeritus of physiology, died August 13 in Los Angeles at age 104. In 1953 Kleitman and his associates identified the period of sleep known as REM, rapid eye movement. His cumulative studies on sleep deprivation established sleep research as a separate and important medical field. He is survived by two daughters.
