The longest unambiguously documented human lifespan is that of Jeanne Calment of France (1875–1997), who died at age 122 years, 164 days. She met Vincent van Gogh when she was 12 or 13. This led to news media attention in 1985, after Calment turned 110. Subsequent investigation found documentation for Calment’s age, beyond any reasonable question, in the records of her native city, Arles, France. More evidence of Calment’s lifespan has been produced than for any other supercentenarian; her case serves as an archetype in the methodology for verifying the ages of the world’s oldest people.
