Theodore Arnold Haultain (1857-1941) was a British writer who published 36 books in his lifetime. The scope of his work was wide, including a romantic handbook dedicated to his daughter, a historical analysis of 19th century Canadian revolt, and even a reflection on the philosophy of walking tours. The son of a Major General in the British army, Haultain was educated in London before moving to Canada, where he spent many years as the secretary to academic and historian Goldwin Smith. After Smith’s death, Haultain would write his memoir and act as his literary executor.
