Born on 13 February 1896, son of Arthur John Cardell, he was educated at Epsom College and St Thomas's Hospital. At Epsom he was awarded the Jenks Scholarship in 1914 and at St Thomas's he was awarded the William Tite Scholarship for 1914-1915, the Peacock Scholarship for 1915-1916 and a second tenure of the Peacock Scholarship for 1916-1917. He then went on active service as a Surgeon Probationer RNVR until the end of the war, returning to qualify from St Thomas's with the Conjoint Diploma in 1919. After qualification he held a series of house appointments at St Thomas's, first as a casualty officer followed by that of house physician, then senior and junior obstetric house physician, then senior and junior ophthalmic house surgeon, and finally resident anaesthetist. After being admitted a Fellow and deciding to take up ophthalmology, he was appointed Ophthalmic registrar working under A C Hudson and P G Doyne. His appointments in 1927 as a consultant were as assistant surgeon to the Western Ophthalmic Hospital, the Central London Ophthalmic Hospital and the Hounslow Hospital. He was at the same time a clinical assistant at Moorfields and oculist to the Leyton Borough Council. Later in his career he became a surgeon at Moorfields, after the amalgamation of the ophthalmic hospitals in 1947, ultimately becoming senior surgeon before his retirement in 1961. He was also ophthalmic surgeon to the Thomas Coram Foundation and to the Royal Masonic Hospital. This last appointment, as a keen mason, he valued highly. During the war of 1939-1945, as a member of the EMS, he was attached to Park Prewett Hospital at Basingstoke and to the Leatherhead Hospital. As a Territorial he became medical officer attached to the London Scottish, with the rank of Captain RAMC (TA), 1924-1928. He was an assiduous and valued member of various committees, chairman of the medical committee of Moorfields Eye Hospital 1959-1951, a member of the advisory committee on blindness, and for twenty years up till 1952 a member of the ophthalmic group committee of the BMA. He was secretary of the Section of Ophthal-mology at the annual meeting of the BMA in 1933 and its President in 1937. Stockily built, as a student he had been a good Rugby footballer and throughout his life, as far as opportunity permitted, was an outdoor man, a keen fisherman and a skilled and industrious gardener. For some time, during the war and after, he operated a farm near Godalming. As a colleague he was efficient and absolutely reliable. An able clinician and competent surgeon he was a staunch friend whose integrity was complete and one who, although he appeared to be rather reserved, had a great sense of humour. He married Audrey Craig in 1927 by whom he had three daughters. He practised at 89 Harley Street, and died suddenly on 6 March 1966 at his home in Cobham, Surrey aged 70.
