Career
He served as President of the Cambridge University Athletic Club. In 1947 Mark finished fourth in the American Automobile Association 440 yards and was selected to represent the United Kingdom in the 400 metres in Paris. In late 1947, he was already on the British shortlist for selection for the 400 metres at the forthcoming London Olympics, when his Olympian good looks led to his being chosen to light the Olympic flame at the opening of the games.
Thus on 29 July 1948 he carried the heavy Olympic torch on the final leg of its journey into Wembley Stadium and lit the flame in its specially-designed bowl.
Following the Olympics, Mark worked as a General Practice in a rural practice in Liss in Hampshire until his retirement. He died of a stroke.
