The Reverend Sir David Thomas Rocyn-Jones, CBE, K St J, DL, JP (16 November 1862 – 30 April 1953) was a Welsh medical officer of health and servant of multiple professional bodies within Wales.
[1] Rocyn-Jones was born in Rhymney to a notable bonesetter, Thomas Rocyn Jones and Mary Rees, who was a descendant of the preacher Rhys Davies.
[3] After passing his DPH qualification in Oxford, he was appointed the first Medical Officer for Health for Monmouthshire in 1908, responsible for ill-health prevention strategies within the county, with a yearly salary of £600.
Nathan would not only follow his grandfather's profession, of working with bones, by becoming an orthopaedic surgeon, but would also continue the family links to rugby by representing Wales in 1925.
[6][7] He is remembered for his beliefs, but also for having a gentle sense of humour he sometimes brought to bear on his medical work, as was shown on one occasion in his Abertillery years when he was required to treat a young rugby supporter injured by a wayward ball.
