Lieutenant Colonel Sir John Reginald Noble Graham, VC, OBE, Argyll and Sutherland Highlanders attached Machine Gun Corps, was born at Calcutta, India, on 17 September 1892. He was the eldest son of Sir Frederick Graham, 2nd Baronet, of Larbert, and Lady Irene Maud Campbell, of Darleith, Cardross.
His siblings were Glenda Victoria Maud, Bevis Royal and Frederick Clarence Campbell.
He was educated at Eton College and Trinity College, Cambridge.
He served in the 9th Battalion of the Argyll and Sutherland Highlanders during World War I. On 22nd April 1917 at Istabulat, Mesopotamia, Lieutenant Graham was in command of a machine gun section which came under heavy enemy fire causing many casualties amongst his men. Despite being wounded himself, he carried the ammunition to enable the one remaining gun he was operating to provide accurate fire on the enemy. This gun was then damaged and he was wounded. He brought a Lewis gun into action with excellent effect until all the ammunition had been expended. He was wounded again and forced to retire from the battlefront.
He died in Edinburgh on 6th December 1980. His VC is held at the Argyll & Sutherland Highlanders Museum at Stirling.
