Randy Gardner

Randy Gardner is an American man from San Diego, California, who once held the record for the longest amount of time a human has gone without sleep. Between December 1963 and January 1964, the then 17-year-old Gardner stayed awake for 11 days and 25 minutes, breaking the previous record of 260 hours held by Tom Rounds. Gardner's record was then broken repeatedly until 1997, when Guinness World Records ceased accepting new attempts for safety reasons. At that point, the record was held by Robert McDonald at 18 days and 21 hours.
