french supercentenarians are citizens, residents or emigrants from france who have attained or surpassed 110 years of age. , the gerontology research group (grg) had validated the longevity claims of 161 french supercentenarians. france was home to the oldest human being ever whose longevity was well documented, jeanne calment, who lived in arles and remembered meeting vincent van gogh when she was a teenager, and lived to age 122 years, 164 days. however, a november 2018 study has disputed calment's case with a hypothesis that calment's daughter yvonne, born 19 january 1898 and claimed to have died in 1934, usurped jeanne's identity in 1934 upon jeanne's death; in this scenario, yvonne calment would have died in 1997, claiming to be jeanne calment and aged 122 but in fact she was aged 99.
