Stewart Myles MacPherson was born in Winnipeg, Canada on the 29 October 1908, and dropped out of High School early. He was doing occasional match reporting when he was urged to test his skills in England. MacPherson worked his passage on a livestock train and reached England in 1936 with the princely sum of £2.10s in his pocket.

      In 1937 Stewart passed a BBC audition as a commentator for the increasingly popular sport of ice hockey. His Canadian accent with a speedy delivery brought a breath of fresh air to sports reporting and soon earned him the sobriquet "The fastest Voice in Radio".

      At the outbreak of World War II, the BBC abandoned outside broadcasting. Over the age to enlist, MacPherson returned to Winnipeg to become a sports editor of a local radio station. A short time later he was invited to join the BBC's war reporting unit. He arrived back in London during the Blitz and was assigned to the RAF where he filed a notable account of the raid over Cologne. He covered everything from Atlantic convoys to the Battle of Arnhem and switched to the ground war as the invasion of Europe began.

By the end of the war, Stewart MacPherson was 'star' status and in a position to give up his employment by the BBC and go free-lance. He provided the commentary on the Oxford and Cambridge boat race, the maiden voyage of the Queen Elizabeth and covered the royal tour of South Africa in 1947. He was the first Chairman of the popular radio programme 'Ignorance is Bliss' and the first host of a new record series 'Down Your Way'. Stewart's greatest broadcasting success was chairing 'Twenty Questions' first aired on 14 March 1947. He compèred three Royal Variety Performances, starred in a Royal Command radio party at Windsor Castle, and in 1947 voted the Daily Mail's 'Voice of the Year' in the National Radio Awards, defeating Winston Churchill to the top spot.

At the peak of his popularity, he gave up a life of 'fame and fortune' for one of relative obscurity and returned to Winnipeg. In 1960 he started up CJAY, a small commercial television station and is still remembered for his daily editorial ‚ 'Stew's Views'.

In 1989, Stewart MacPherson was inducted in to the Canadian Broadcast Hall of Fame. He was married to Emily Comfort who predeceased him, and he left a son and daughter when he died at Winnipeg on 16 April 1995.
