William Paton Ker
William Paton Ker (usually referred to as "W. P. Ker"; 30 August 1855 – 17 July 1923) was a Scottish literary scholar and essayist.
He was appointed to a fellowship at All Souls College, Oxford in 1879. He became Professor of English Literature and History at the University College of South Wales, Cardiff in 1883; and moved to University College London as Quain Professor in 1889. He was the Oxford Professor of Poetry from 1920 to his death whilst hill-climbing in Europe. A W. P. Ker Memorial Lecture is held at Glasgow University in his honour.
- "... what good angel lured me into Blackwell's one afternoon and, from such a wilderness of volumes, picked out for me the essays of W. P. Ker? No other critic whom I have subsequently read could have granted me the same vision of a kind of literary All Souls Night in which the dead, the living and the unborn writers of every age and tongue were seen as engaged upon a common, noble and civilizing task. No other could have so instantaneously aroused in me a fascination with prosody, which I have never lost."
