Sir Errol Manners KBE (29 June 1883 – 23 October 1953) was a British Royal Navy Rear admiral and author on theology and British Israelism. He completed fifty-two ocean convoys during the Second World War, including ONM 249 which consisted of 153 ships. He wrote segments of research in a lengthy book titled Bible Research published in 1946, which quickly became popular among proponents of British Israelism for its chapter titled "The Hebrew origin of English. Israelite heraldry in Anglo-Saxon countries".
