Born on May 16th, 1841, in Old Folkestone close to the harbour. He was the eldest child of Sylvester Eastes, MRCS, JP, the Mayor of Folkestone, at that time a small place with fields covering the West Cliff up to the Parish Church. Eastes went to school at St Margare's Bay, then to Tonbridge Grammar School, where the boys got up at 5 am in the summer for preparation, lasting to 8 am. In 1854 he was transferred to Maidstone, where at the end of the Crimean War he won a prize for a school poem on 'Peace'. At the age of 15 he was apprenticed to his father, after which in 1860 he entered Guy's Hospital, where he proceeded to the London Degree and to the Fellowship of the College of Surgeons. He was House Surgeon, and then for two years Surgical Registrar and Tutor. After six months' study in Paris he settled in general practice at 5 Albion Place, W, in succession to Dr Egbert W Charlton. In 1863 he was one of the founders of the Guyite Club, composed of forty-three original members with a motto 'Dum licet nobis', and was its Secretary to the end of his life, when the little society had dwindled to fifteen. With the aid of the Guy's surgeons he was able to develop a special practice in the administration of anaesthetics; he was for fourteen years Anaesthetist to the Great Northern Hospital, and was one of the founders of the Society of Anaesthetists. He acted as Secretary to the first British Medical Association Committee of Inquiry, and devoted much time to a tabulation of the results of the inquiry into anaesthetic administrations. From about 1874 he acted with Alban Doran and Fancourt Barnes on the editorial staff of the *British Medical Journal*, under the Editor, Ernest Hart, and he continued throughout his life to contribute to it. At the Metropolitan Counties Branch he was Secretary (1886-1888), Treasurer (1892-1899 and 1901-1903), President (1900), and Secretary of the Investigation Committee (1885-1887). Up to 1908 he was the Branch Representative on the Council, and a member of the Finance and Journal Committee. At the Leeds Meeting in 1889 he was Secretary of the Section of Public Medicine, and at the Newcastle Meeting in 1893, Vice-President of the same section. He was President of the Harveian Society in 1895. Further, he was instrumental in erecting on the Leas at Folkestone the memorial statue to Harvey at his birthplace. He published a short account of Harvey in 1871. In later life he practised at 35 Gloucester Terrace. He was fond of riding, shooting, the sea, and travel. After a short illness, from which he seemed to be recovering, he died with an attack of thoracic pain on January 23rd, 1909, and was buried in Folkestone Cemetery. He had married in 1869 Miss Fanny Elizabeth Friend, of Hambledon, who survived him with two daughters and one son, Dr George Leslie Eastes, pathologist. His younger brother was Thomas Eastes (qv).
