Ivan Müller was the assistant editor of the Pall Mall Gazette.
JW was in correspondence with Müller in 1895 over a letter from George Moore to JW that was published in the Pall Mall Gazette. JW considered the printing of a private letter to be libellous. However, relations stayed positive, JW writing, 'though this time disappointed, I have to thank you for all your courtesies' (#04394).
He was the author of several books, including Lord Milner and South Africa, London, 1902.
