He was educated at University College School and St Bartholomew's, where he served as house surgeon, and took honours in the London BS examination in 1894. He served as temporary assistant physician at the Queen's Hospital for Children at Hackney, and was later surgeon to the Mildmay Cottage Hospital. He began to practice in partnership with his father at Highbury and kept on this general practice after his father's death in 1893. He was a Fellow of the Hunterian Society. In 1913 he retired to St Albans, and during the war of 1914-18 helped local practitioners there. In 1919 he came back to London, taking consulting rooms in partnership with John Adams, FRCS, in Aldersgate Street in the City, and lived at 42 Lyndale Avenue, Finchley Road, NW2. He later retired to Firbank, 4 St John's Road, Sevenoaks, Kent, where he died on 25 August 1944, aged 84, and was buried at Greatness cemetery, Sevenoaks. He had married about 1886 Annie Martha Everard, who predeceased him, leaving two daughters and one son, Christopher Langton Hewer, MRCS 1918, in practice at St Albans.
