Joseph O'Neill was an Irish novelist.
O'Neill was born in the Aran Islands, County Galway, Ireland, in 1886. He became a school inspector and subsequently Secretary of the Department of Education in the newly formed Irish Free State. He wrote five novels, of which the best-known was Land Under England, a science-fiction account of a totalitarian society ruled by telepathic mind control, cited by Karl Edward Wagner as one of the thirteen best science-fiction horror novels.[1][2] His other novels include the time-travel novel Wind From the North and the future-war story Day of Wrath.[2] He died in 1953.
He was the husband of Mary Devenport O'Neill, poet and friend of W.B. Yeats, who consulted her when writing 'A Vision'. Devenport O'Neill was an important writer in her own right, whose work warrants further study.
