Born on 15 December 1884 at Pentre, Glamorgan, son of Elias Henry Davies, an influential figure in the public service of South Wales, and Ann Jones, his wife, he was educated at Porth County School and University College, Cardiff, graduating with first-class honours in science in 1906, and was awarded the Hughes memorial gold medal and the Glamorgan scholarship. He was demonstrator of anatomy at Cardiff, and then entered University College Hospital Medical School, London. He was house-surgeon and house physician at University College Hospital, and resident medical officer at the City of London Lying-in Hospital. He served as obstetric registrar at University College Hospital, medical officer to out-patients, pathologist, and registrar at the Hospital for Women, Soho Square, and obstetric surgeon to out-patients at Queen Charlotte's Maternity Hospital. He was ultimately consulting gynaecologist to the Hospital for Women and to Queen Charlotte's and also to the West Lon-don Hospital and Finchley Memorial Hospital. He contributed to the well-known *Queen Charlotte's Textbook of the Practice of Obstetrics*. When the British (afterwards Royal) College of Obstetricians and Gynaecologists was formed in 1929 Davies was elected a foundation Fellow. He also served on the council of the Section of Obstetrics in the Royal Society of Medicine. He examined for the Conjoint Board and the Central Midwives Board. He had a large consulting practice at 23 Harley Street, but retired some years before his death to Porthcawl, Glamorgan, living first at Ty Gwyn (The White House), Green Avenue, and latterly at Sea Field, Loughor Gardens, where he died on 24 April 1956 aged 71. He married in 1920 Gwladys, daughter of Dr Rhys David Morgan JP of Ynys-y-Bwl; Mrs Davies survived him briefly, dying at Porthcawl on 6 December 1956. One of their two daughters was a doctor.
