Thanks for the query.
Jeanne Louise Calment is a french who holds the record for longest human lifespan of 122 years and 164 days. This fact has been confirmed by the Guinness book of World records. Jeanne outlived both her daughter and grandson and lived in France her entire life.
Edit: Thanks to Reshmi Sarkar for pointing out that I have written about the oldest person, Jeanne Louise Calment, who is in fact female. As per Guinness Book of world records - Yasutaro Koide (Japan) has been officially recognized as the Oldest person living (male) at the age of 112 years and 161 days on 20th August, 2015.
