Robert Armstrong Jones

Sir Robert Armstrong-Jones, CBE (born Robert Jones; 2 December 1857 – 31 January 1943) was a Welsh physician and psychiatrist. He was the grandfather of Antony Armstrong-Jones, 1st Earl of Snowdon (d. 2017).

He was born in Ynyscynhaearn, Caernarvonshire, the son of a Congregational minister. He was educated at Porthmadog Grammar School and Grove Park School, Wrexham, going on to study medicine at University of Wales, Bangor, and St. Bartholomew's Hospital. Becoming a specialist in the treatment of mental illness, he worked as a junior medical officer at the Royal Earlswood Institution and Colney Hatch during the 1880s, and became resident physician and superintendent of Earlswood Asylum in 1888. In 1893 he became superintendent of the London County Council's Claybury Asylum, where he developed new treatments. In the same year he married Margaret Roberts (1868–1943), the elder daughter of Sir Owen Roberts of Plas Dinas, Caernarfon.

Armstrong-Jones lectured at St Bartholomew's Hospital, and became consulting physician in mental diseases to the military forces at London and Aldershot. In 1913, he assumed the additional surname of Armstrong. During World War I, he was designated a Lieutenant-Colonel in the Royal Army Medical Corps; he was knighted in 1917, and after the war he was appointed a Commander of the British Empire (CBE). He was appointed High Sheriff of Caernarvonshire for 1929.

Armstrong-Jones remained attached to Claybury, where he died at the age of 85. His wife survived him by only four months. Their daughter, Elaine, married Colonel Charles Wauchup. Armstrong-Jones's son, Ronald, became a barrister and was himself the father of Antony Armstrong-Jones, 1st Earl of Snowdon, the brother-in-law of Queen Elizabeth II.
