Col Bryson, of Hightown, will join dignitaries and aristocrats at Liverpool town hall on Thursday to mark his 70 years in public life.
His career started in 1936 when he was commissioned to the Territorial Army by King Edward VIII.
During his lifetime, Col Bryson, who grew up in Woolton and Calderstones Park, has gained a long list of achievements.
He held positions including chairman of the Medical Appeal Tribunal, Senior District Registrar of the High Court of Justice and Liverpool Admiralty Registrar, president of the Liverpool Law Society, chairman of the Mayor's Poppy Fund, president of the North West Cancer Research Fund, organiser of the annual Remembrance Day commemorations at the Lime Street war memorial, and Commissioner of Taxes from 1968 to 1988.
He is also an appointed Knight of Commander of the Papal Order of St Gregory the Great, and was elected a Knight of the Honourable Society of Knights of the Round Table.
But one of his most startling achievements was when he was sitting as a bankruptcy judge in a case over infamous nightclub owner George Wilkie in 1960.
