Jeanne Louise Calment (21 February 1875 – 4 August 1997) was a French supercentenarian and at the time of her death at age 122 years, 164 days the verified oldest person in history as well as the only person who has surpassed 120 years of age, although her claimed age is possibly disputed.
On 17 October 1995, Calment reached 120 years and 238 days to become the "oldest person ever" according to Guinness World Records, surpassing Shigechiyo Izumi of Japan, whose claim (120 years 237 days old at the time of his death on 21 February 1986, Calment's 111th birthday) has since been discounted. Calment also holds the record for being the oldest living person for the longest period of time, by far – with nearly nine years and seven months, counting from the death of Florence Knapp on 11 January 1988, to her own death on 4 August 1997.[1]
She was the last remaining undisputed person born in the 1870s.[1] On 12 July 1995, Tane Ikai of Japan died, and Calment became the last living link from the 1870s. Following Calment's death on 4 August 1997 at 10:45 CET, then 116-year-old Marie-Louise Meilleur became the oldest living recognized person.
