W.P. Ker Lecture
The W.P. Ker lecture was a yearly lecture at the University of Glasgow. It is now a full lectureship. It was instated in 1938 in honour of William Paton Ker, of whom Tolkien spoke with reverence in The Monsters and the Critics.
On various websites with a "Tolkien Timeline" (a selection:), the date of this lecture is incorrectly given as 1933 (or "circa 1933"). It seems to be based on a misreading and ignorant copy-pasting.
