The Old Wulfrunians' Association (OWA) gathered for an annual dinner at the Compton Road school last night,
Among them was 96-year-old Fred Howarth, who still has his old boys blazer from when he joined the OWA, and former arts tutor Charles Viner, who celebrated his 100th birthday three months ago.
Wolverhampton born Mr Howarth, a former engineer with car company Sunbeam, now lives in Gloucester. He attended the school between 1922 and 1927.
His OWA association blazer dates back to when he joined the group not long after leaving the school. It is now more than 70 years old and still in pristine condition.
Mr Howarth said: "I am very glad I have still got this but I only wear it on special occasions."
"I very much enjoyed my time at the school and particularly liked the sports including football, running and cricket."
"The only difference today is the new buildings; when I was here I remember there were still some World War One army huts around the corner."
He left the grammar school at 16 to pursue ane ngineering apprenticeship with Sunbeam.
Robin Cooper, aged 69, was born in Great Brickkiln Street just off the Ring Road St Marks. He attended the school between 1949 and 1956 and has gone to work in the pharmaceutical industry, living in America since 1965.
He currently works for a pharmaceutical company in San Francisco, helping to discover new drugs.
He said: "I have been pretty successful and I think I owe the school a huge amount for helping me on my way. I miss thepeople and I miss the school but my office looks out onto the harbour of San Francisco bay which isn't too bad."
Returning to the school was former arts tutor Charles Viner, who lives in Telford.
He said he still looked back on his time with the school fondly and added: "One of my former pupils has gone onto become head of sculpture at the Royal College of Art in London and some others have achieved a lot as well."
"It is nice to see what old students are up to and how they have been doing."
Former chartered accountant Arthur Nelson, aged 77, who is originally from the West Park area of Wolverhampton, attended the school through the war years, leaving in 1947. His twin sons Jonathan and David, now aged 45, were pupils between 1974 and 1981, and chartered surveyor Jonathan, who now lives in Albrighton, joined his father for the evening.
Mr Nelson Snr said: "I was very happy at the school. Although I was here during wartime the teachers did their best to minimise the impact it had on us."
His son Jonathan added: "I still keep in touch with a few friends from my year - I think people look back on it fondly as it gives a great start."
Wolverhampton Grammar School was founded in 1512 by Sir Stephen Jenyns. It is still going strong nearly 500 years later and moved to its current home in Compton Road in 1875. The OWA has helped provide a way for former students to stay in touch through sporting and social activities.
The OWA has around 175 members spread from Shifnal to the United States.
One of the organisers of the annual dinner is 66-year-old Philip Moore, of Shifnal, who attended the school between 1952 and 1960.
He said: "We only have this event once a year and it is a good way to catch up with people. I think nostalgia is one of those things that gets better with age. People change but you can always still recognise them."
