Born in Liverpool, the third son of J H Barendt. Educated at Liverpool College and St Petri School, Danzig. Received his medical training at the University of Liverpool, where he had a distinguished career, gaining honours in materia medica in the 1st MB, 1888, and the Roger Lyon Jones Scholarship in Pathology, a subject which interested him. After qualification he travelled in France, Germany, and Austria, studying under Hebra, Kaposi, Neumann, Max Joseph, and Lassar. Returning to Liverpool he became House Physician in the Royal Infirmary, Senior Medical Officer to the Bootle Borough Hospital, and Assistant Medical Officer to the Rainhill Mental Hospital. Specializing in dermatology, he was appointed Hon Surgeon to St George’s Hospital for Diseases of the Skin at Liverpool, and Physician to the Department of Diseases of the Skin at the Royal Southern Hospital, posts which he held to the end of his life. He won great distinction as a syphilologist, was one of the first practitioners in Liverpool to make use of intravenous injections of arsenical compounds, and was appointed to the charge of the special clinic for venereal disease at Bangor Infirmary. An admirable linguist, Barendt spoke French, German, and Russian, and often acted as a translator of foreign classics for the New Sydenham Society. He took an active part in medical societies and medical journalism, and was in turn Librarian, Editor of the Journal, and Vice-President of the Liverpool Medical Institution. He was also a strong supporter of the Medical and Literary Society. In his contributions he was minutely thorough and accurate, his German strain thus becoming apparent. His biographer says: “So German was he in what old writers would have called his genius, that he was apt to miss the wood for the trees”. He married a daughter of Dr Crowe, of Liverpool, by whom he had three sons and two daughters. One of his sons was studying medicine in 1926. He died suddenly at his residence, 65 Rodney Street, Liverpool, on Oct 28th, 1926. His publications, which were numerous, are mostly on dermatological subjects.
