Gerritdina Schellevis-Slaghuis (12 December 1890 - 13 November 2001) was a Dutch supercentenarian whose age is officialy validated.
Gerritdina Schellevis-Slaghuis was born in the village of Enter in the province of Overijssel, The Netherlands. She married and got seven children. She became a widow in 1954.
On 7 January 1997, when Mrs. Schellevis-Slaghuis was 107 years old, she became the oldest living person in Overijssel. On her 110th birthday on 12 December 2000, it was mentioned that she was the first person ever from the province of Overijssel who reached the age of 110 years, and thus became the first ever supercentenarian of that province. She also was the third oldest living person in The Netherlands at the time, behind Catharina van Dam-Groeneveld of South-Holland and Hendrikje van Andel-Schipper of Drenthe. After the death of 113-year-old Mrs. Van Dam-Groeneveld on 16 February 2001, she became the second oldest living person in The Netherlands, after Mrs. van Andel-Schipper (who eventually became the oldest Dutch person ever).
Mrs. Schellevis-Slaghuis passed away a month before her 111th birthday, on 13 November 2001 at the age of 110 years, 336 days. She remains the oldest person ever from Overijssel. When she died, only the Reformatorisch Dagblad (a Dutch protestant newspaper) reported about her death; no other newspaper in The Netherlands, not even the large newspapers, reported about her passing.
