Leo Genn was the son of a successful jewelry merchant Woolfe . He embraced TV playhouse, both American and British programs, and US/UK episodic series through the period, as well as more outings on Broadway. He made six appearances on the Great White Way - the last in a short run of "The Only Game in Town" in mid 1968. All along Genn's voice had found welcoming slots in narration. Beside films, he was the voice of the royal coronation programs of 1937 and 1953. And he always kept a foot in his first love, British theater; he was a governor of London's The Mermaid Theatre.
While a Lieutenant-Colonel in the British Army, he was one of the Prosecuting Officers at the British-mounted 1945 Belsen War Crimes trial.
His surname was pronounced with a hard "G".
