Born in London on 10 April 1874 the fifth child and second son of John Theodore Rodocanachi, merchant, and Fanny Mavrogordato, his wife. He was educated at University College School, University College, and University College Hospital. He won an exhibition and the gold medal in organic chemistry at the BSc examination in 1893, took honours in medicine and obstetrics at the MB in 1895, and proceeded to the MD the next year. After serving as ophthalmic assistant at University College Hospital, he was house surgeon at the District Hospital, Ashton-under-Lyne, Lancashire, and remained on the staff becoming eventually consulting surgeon. He was also surgeon to Ancoats Hospital, Manchester. Later he practised at Stalybridge, Cheshire. Rodocanachi was a member of the Manchester Medical and Pathological Societies. He married on 18 June 1913 Florence Lilian Andrew, who died on 14 November 1937, but without children. After his wife's death his sister kept house for him at Aingarth, Stalybridge, where he died on 13 October 1942, aged 68. He was of a reserved and somewhat cynical temperament. He left the residue of his estate to the endowment fund of the Ashton-under-lyne District Infirmary; his other legacies included £1000 to University College Hospital.
