Who is the longest lived person in the world?

The longest unambiguously documented lifespan is that of Jeanne Calment of France (1875-1997), who died at age 122 years and 164 days. She met Vincent Van Gogh at age 14.This led to her being noticed by the media in 1985, at age 110. Subsequent investigation found that her life was documented in the records of her native city of Arles beyond reasonable question. More evidence for the Calment case has been produced than for any other supercentenarian case, which makes her case a standard among the oldest people recordholders.(Source wikipedia)
