Ollie Cromey of Rowley Close, Bracknell, a great-grandfather, celebrated the magnificent milestone along with about 80 guests at Dennis Pilcher House on Sunday.
Bracknell Forest mayor Cllr Alan Kendall was among those to wish Mr Cromey Happy Birthday on his special day.
Mr Cromey was born in Ealing and he spent the first half of his life there, before moving to Perry Oaks, Bracknell, in the early 1980s.
In 2001 he and his wife Marjorie moved into a bunga-low in Rowley Close but Mrs Cromey died soon afterwards.
However, Mr Cromey – who was a sapper in the Royal Engineers and part of the D-Day Invasion in Normandy in 1944 – has been a popular and friendly member of the community at Dennis Pilcher House ever since.
His trade during the war years was as a well-borer, bringing fresh drinking water to troops engaged in the conflict. After the war he worked for many years at the AEC in Southall and then his final job was at EMI working on the first body scanners.
There were four generations of the family at the party and they all joined in the toast, given by Cllr Kendall.
Mr Cromey said: “The secret to my longevity has been my keenness to stay fit despite suffering from asthma. I was a keen footballer in my youth and did some boxing, and I continue to do some form of exercise each day.”
