Geert Adriaans Boomgaard becomes the first validated supercentenarian

Background. Geert Adriaans Boomgaard was born in Groningen, Netherlands, in September 1788. Little is known about his personal life, but his birth records indicate he was the son of Adriaan Jacobs Boomgaard and Geesje Geerts Bontekoe. His longevity was documented through historical records, establishing him as a key figure in the validation of extreme human ages.

Validation. On 8 January 1897, Boomgaard surpassed the final age of Belgian Pierre Darcourt (108 years and 108 days) to become the oldest man ever. By 10 April 1898, he was older than the previous titleholder, 109-year-old Norwegian woman Kirsti Skagen (1788–1897), making him the oldest ever verified person at that time. Scholars generally accept him as the first validated supercentenarian case on record.

Legacy. Boomgaard is generally accepted by scholars as the first validated supercentenarian case on record. The first female supercentenarian and his successor was Margaret Ann Neve, who surpassed his final age, dying at almost 111 (1792–1903). His lifespan as the longest-lived male was not surpassed until 21 February 1960, by Robert Early (1849–1960) of the United States.
