Joseph O'Neill (1878-1952)Joseph O'Neill was an Irish educationist and author. He worked as the Permanent Secretary to the Department of Education, Irish Free State, between 1923 and 1944. Although not strictly an SF writer, O'Neill used SF instruments to make cultural and political points with great eloquence. Land Under England (1935), about an underground world where citizens are controlled by telepathy, is a satire on Hitlerian totalitarianism.
