Abstract

In 1997 Jeanne Calment died at a claimed age of 122 years and 164 days. The authenticity of her age was validated by Michel Allard and Jean-Marie Robine who published popular books about her case. In 2018 Nikolay Zak presented evidence that Jeanne Calment’s daughter Yvonne had assumed her mother’s identity. In 2019 the original validators and their colleagues defended their work and tried to refute the points of evidence made by Zak. In this comment we examine their arguments and find that they do not hold up. We provide new damning evidence in favour of the identity switch hypothesis.
