LongeviQuest in Paris for 16th Supercentenarian Seminar

Earlier this month, LongeviQuest researchers Guillaume Legris and Jimmy Lindberg attended the 16th Supercentenarian Seminar hosted in Paris.

The researchers presented findings on four of the earliest known verifiable centenarians, all of whom lived during the 1600s or earlier. Their presentations included a variety of documentation and reconstructed family trees, along with discussions of potential issues related to the age claims.

You can read about some of the centenarians discussed here: Searching for the first (verifiable) centenarian, which includes individuals such as Gershom Rice (1667?–1768), who lived in what would later become the United States, and Martha Thomlinson (ca. 1668?–1769) of England.

Do note that additional, potentially earlier centenarians were discussed, and there is an intention to publish research on them at a later date.

Researcher Jimmy Lindberg also presented posters on work conducted on Eliza Underwood (1866?/67–1981), who at the time of her death was the oldest known person of all time. In addition, Lindberg presented a poster on the familial longevity of relatives of Swedish semi‑supercentenarians, finding evidence that these relatives tend to live longer than the general Swedish population.

LongeviQuest was pleased to participate and we thank the INED and the International Database on Longevity for hosting the event.
