Harold Frederick Stewart (14 December 1916 – 7 August 1995) was an Australian poet and oriental scholar. He is chiefly remembered as the enigmatic other half of Ern Malley.Stewart's work has been associated with James McAuley and A. D. Hope, belonging to a neo-classical or Augustian movement in poetry, but his choice of subject matter is different in that he concentrates on writing long metaphysical narrative poems, combining Eastern subject matter with his own metaphysical journey to shape the narrative.He is usually described by critics as a traditionalist and conservative but described himself as a conservative anarchist. A witty and engaging letter writer, many examples have been retained by the National Library in Canberra. Leonie Kramer in The Oxford History of Australian Literature, p. 371, grades the literary quality of Ethel's letters as equal to those of Patrick White, Peter Porter and Barry Humphries.
