Born in Australia on 13 February 1881, the seventh child and third son of Frederic Chapple, CMG, head master of Prince Alfred College, Adelaide, and his wife Elizabeth Sarah Hunter. Chapple graduated in science at Adelaide University and then entered St John's College, Cam¬bridge. He took honours in the Natural Sciences Tripos, Part I, 1904, and won a half-blue for tennis; he was also prominent at rugby football, swimming, and acting. He entered Guy's Hospital in 1905 when Sir William Arbuthnot Lane, whose daughter he afterwards married, was at the height of his fame as surgeon to the hospital. Chapple served as an assistant in the obstetric department of the Charite-Krankenhaus, Berlin, and was then appointed obstetric registrar at Guy's. In 1913 he was appointed obstetric surgeon on the death of J H Targett, FRCS, and ultimately became senior obstetric surgeon and gynaecologist. He was also lecturer on obstetrics and gynaecology at Guy's Medical School. Chapple was consulting obstetric surgeon and gynaecologist to the London Jewish Hospital, the Victoria Hospital, Kingston, St John's Hospital, Lewisham, and the Buchanan Hospital, St Leonards. During the first great war he served in France as a captain, RAMC. He examined in midwifery and diseases of women for the Royal College of Physicians and the Universities of Cambridge and London. Chapple was a foundation Fellow of the British, now Royal, College of Obstetricians and Gynaecologists. Chapple married in 1911 Irene Briscoe Arbuthnot Lane, second daughter of Sir W A Lane, FRCS, who survived him with two sons. He died at Orchard Court, W, on 8 March 1945, aged 64. He had practised at 149 Harley Street. A memorial service was held at Guy's Hospital on 20 March. He left, subject to life interests and legacies, the residue of his fortune to Prince Alfred College, Adelaide. Chapple was a collaborator in the well-known text-books "by Ten Teachers" - *Midwifery* 1917 and *Diseases of women* 1918, both of which went through several editions. But he made his mark in personal and clinical practice. Possessed of charm, courtesy, and kindliness, he was peculiarly successful with timid or difficult patients. He was also very helpful to his students and assistants, though not so unaware of their shortcomings as he appeared to be. He was president of the Medical Golfing Society from 1940 to 1945.
