Photograph via Wikipedia. Thatâs Jeanne Calment, a French citizen who has the longest confirmed human lifespan in history at 122 years and 164 days. She was born on February 21, 1875 and passed on August 4, 1997 [Source]. Sheâs lived through both world wars, seen humankind land on the moon and witnessed the birth of the Internet.
