As Scottish Secretary, he presided over the last execution in Scotland when Henry John Burnett was hanged at Craiginches Prison in Aberdeen on the morning of 15 August 1963 by the hangman Harry Allen for the murder of merchant seaman Thomas Guyan.
On 3 May 1974 Noble was elevated with a life peerage as Baron Glenkinglas, of Cairndow in the County of Argyll.[1]
Although he was a good 25 years younger than the architectural historian Harry Stuart Goodhart-Rendel, the two had a very friendly feud. Noble is said to have joked that they were "best of enemies."
