Karl Leyser

Karl Joseph Leyser (24 October 1920 – 27 May 1992) was a German-born British historian who was Fellow and Tutor in History, Magdalen College, Oxford, from 1948 to 1984, and Chichele Professor of Medieval History at Oxford University, from 1984 to 1988.

Early life and military service Leyser was born in Düsseldorf to Otto Leyser, a manufacturer of belts and braces, and Emmy Leyser (née Hayum). In 1937 the family was declared stateless by the Nazi regime and Karl moved to England with his sister Dorothée while their parents escaped to the Netherlands.

Leyser began studying at St Paul's School in London in 1937, with the medieval historian Wilhelm Levison, a relative of Otto's, helping with the fees. He was elected a Fellow of the British Academy in 1983 and a year later was appointed Chichele Professor of Medieval History at All Souls College.

He wrote extensively on early medieval Germany, with a particular focus on Saxony, publishing over 70 articles and books in both German and English. His interests included royal rule and royal personality, diplomacy, politics, warfare, and the early Holy Roman Empire.

Peter Brown, who attended a lecture series of Leyser's as an undergraduate in 1956, remembered him thus in his Journeys of the Mind:
