In 1948, Agnes Headlam-Morley became the first woman to receive a full professorship at which UK university?

Agnes Headlam-Morley (10 December 1902 – 21 February 1986) was a British historian and academic. From 1948 to 1971, she was Montague Burton Professor of International Relations at the University of Oxford. Upon her appointment in October 1948, she became the first woman to be appointed to a chair at Oxford.

Headlam-Morley was educated at Wimbledon High School, an all-girls private school in Wimbledon, London. She studied modern history at Somerville College, Oxford, graduating with a second class Bachelor of Arts (BA) degree in 1924. She then undertook research in modern European political history, and completed a Bachelor of Letters (BLitt) degree in 1926. As per tradition, her BA was promoted to a Master of Arts (Oxon) degree.

In 1932, Headlam-Morley was elected a Fellow of St Hugh's College, Oxford. Until her retirement, she was a tutor in history and politics at St Hugh's. She specialised in Anglo-German relations and diplomatic history. She belonged to the traditional school of international relations in which the subject was considered a subfield of history and not a social science. In 1971, she stepped down from the chair and retired from full-time academia.

In 1948, Headlam-Morley was made an honorary fellow of Somerville College, Oxford (her alma mater). She was made an honorary fellow of St Hugh's College, Oxford in 1970; the year before her retirement.
