Pierre Joubert Sr. (July 15, 1701 - July 19, 1766) and Pierre Joubert Jr. (March 10, 1732 - November 16, 1814) were a father and son who were mistakenly conflated into a single Pierre Joubert (July 15, 1701 - November 16, 1814), listed in Guinness World Records for decades as the oldest man ever at the supposed age of 113 years, 124 days, until an investigation revealed that Joubert had died in 1766 aged 65 years, 4 days, and that the man who died in 1814 was his son, and the actual age of the latter was 82 years, 250 days, although Pierre Joubert Jr claimed to be 105 at his death.
