James Bedford, cryopreserved in 1967 and still maintained by Alcor Life Extension Foundation, was born on April 20, 1893. That means that he is now the longest-surviving human being ever. Previously, Jeanne Calment was listed as the longest-lived human being ever verified. She was born on 21 February 1875 and died on 4 August 1997, making her 122 years, 164 days old (or 44,724 days).
