She is also the oldest person never to have held the title of the world's oldest living person, since Jeanne Calment, who was about five months older, was still alive at the time of Hannah's death. Before her death, Hannah claimed to be a year older, but investigation by the Social Security Administration's ``Kestenbaum'' study in 2003 proved that her age at death was actually 117 years, 248 days. At the time of her death in March 1993, Hannah was the oldest American ever and second oldest person ever whose age has been verified, behind only Jeanne Calment.
