One of his legacies is that today, Morison International (his namesake), is now a leading global association of 76 independent firms in 55 countries.
Before his accounting career, Mr Morison, an undergraduate at University of Cambridge joined the RAF immediately at the outbreak of the Second World War. During one of his bombing missions over Germany his plane crashed and he was a prisoner of war in Stalag Luft III, immortalised by the film The Great Escape. He was part of the great escape team responsible for improvising and producing air extractor fans to pump air into the three escape tunnels known as Tom, Dick and Harry.
He escaped by marching out of Stalag III, escorted by fake guards, changed into a fake Luftwaffe officer's uniform, penetrated a German airfield, got into the cockpit of a Luftwaffe aircraft with the intention to fly to Sweden and back to the UK. Unfortunately he was caught while trying to start the German plane to take off to freedom and was imprisoned at the infamous Colditz until he was liberated towards the end of the war.
After the war he qualified as a Chartered Accountant, joined the firm that bore his family name which later merged with another City firm, Monkhouse Stoneham (established 1894), and the merged firm became Morison Stoneham. As a former Senior Partner of Morison Stoneham he helped the firm emerge as a leading City of London mid-size firm.
Tributes to Mr Morison's life have been published widely from The Daily Telegraph to the International Accounting Bulletin. Those that knew him held him in extremely high regard.
According to Stephen Chang, Vice Chairman of Morison International and long-term colleague and friend "He was one of the very rare quintessentially unassuming English gentlemen whose noble values were a natural part of normal living. He always led by example and provided inspirational leadership in his own quiet way."
