Henry Bruce Wright Armstrong, Northern Irish barrister, politician and Unionist Member of Parliament (MP) for Mid Armagh from June 1921 until 1922, dies on December 4, 1943.

Born on July 27, 1844, at Hull House, Sholden, Kent, England, Armstrong is the second surviving son of William Jones Wright Armstrong, Justice of the Peace (JP), Deputy Lieutenant and High Sheriff of Armagh, and Frances Elizabeth, widow of Sir Michael McCreagh, and daughter of Major Christopher Wilson. He is educated at The Royal School, Armagh, and Trinity College, Cambridge, gaining a BA (2nd Class Law Tripos) in 1867 and an MA in 1870. He is called to the English bar (Inner Temple) in 1868. He practises in England for four years. During this period, he also travels widely in Europe, the East, and the Far East, witnessing the last of the German army leave France after the Franco–Prussian War (1870–71) and acting as a copy carrier for The Daily News while in Metz in 1873.

Known principally for his contribution to Ulster politics at local level, Armstrong serves as JP and is appointed High Sheriff of Armagh for 1875 and High Sheriff of Longford for 1894. He is a County Councillor for Armagh from 1899 to 1920, and a Member of the Irish Convention in 1917–18. Vice-Lieutenant of County Armagh in 1920, he is a Senator of Queen’s University Belfast from 1920 to 1937.

Armstrong is returned unopposed to the Imperial House of Commons for Mid-Armagh in the 1921 Mid Armagh by-election, at the advanced age of 76, becoming one of the oldest first-time MPs whose birth date is recorded. Certainly, he immediately becomes the oldest member of the current House of Commons. He is a Senator of Northern Ireland from 1921 to 1937, and Lord Lieutenant of Armagh from 1924 to 1939. For twenty-five years he is a member of the Representative Body of the Church of Ireland. He is Chairman of the County Armagh Education Committee from 1925 to 1931, and President of the Association of Education Committees of Northern Ireland. In 1932, he is made a Privy Councillor for Northern Ireland, and in 1938 he serves as a Justice for the Government of Northern Ireland in the absence of the Governor.

In his later years, Armstrong provides financial support for Jewish refugees fleeing Nazi-occupied Europe.

In 1883, Armstrong marries Margaret Leader, daughter of William Leader of Rosnalea, County Cork. They have five sons and three daughters, of whom C. W. Armstrong also becomes a politician.

Armstrong dies at his home in Dean’s Hill, Armagh, on December 4, 1943, at the age of 99 years.
