The Nottingham-based home invited Kathleen’s friends, family, fellow residents and staff to celebrate the milestone.
Born in April 1917 in Long Eaton, Kathleen never left the area, and has lived at the care home since September 2013, on Longmoor Lane, Sandiacre.
She has two children, daughter Zena and son Cliff, as well as five grandchildren and five great grandchildren.
They all visited the home for Kathleen’s party, when she was presented with three birthday cakes, two bouquets of flowers and a card from the Queen.
She said: “It’s lovely to celebrate my birthday with my family and my friends at the care home.”
Kathleen lived on Cranmer Street, Long Eaton, before meeting her future husband at her aunt’s wedding, where she was a bridesmaid.
From the age of 14, she worked as a clerk, rising to chief wage clerk by the time she married James Frederick William Cattermole in April 1947, at Ilkeston Registry Office.
During World War 2, she received training on how to put out fires with stirrup pumps, spending her evenings fire watching.
She said: “We had training but never had to put any fires out. We also had two soldiers billeted with us during the War. Everyone had to do their bit.”
Kathleen has always been a keen dancer and used to tour the Nottingham clubs, ballroom and sequence dancing.
She was also a pianist and performed alongside her brother, Harold Mason, who played the violin. She said: “He used to tap me on the head with his bow if I ever went wrong.”
Samantha Ely, home manager at Longmoor Lodge Care Home, said: “We always hold a special celebration for residents during their birthday but a 100th birthday is an extra-special occasion.
“We were delighted so many of Kathleen’s family could come and enjoy the party with her. It made her day and she couldn’t stop smiling.”
