The Hersch Lauterpacht Memorial Lecture is an annual three-part lecture series given in Cambridge to commemorate the unique contribution to the development of international law of Sir Hersch Lauterpacht. These lectures are given annually by a person of eminence in the field of international law.

We will come together to celebrate the life and scholarship of our colleague and friend, Professor Karen Knop (1960-2022). Karen, until her untimely passing, was the Cecil A Wright Chair at the University of Toronto’s Faculty of Law. A long-time friend of the Lauterpacht Centre, Karen was to have delivered the Centre’s 2025 Hersch Lauterpacht Memorial Lectures.

The 2025 Lectures will take place on 13 and 14 March, over four special sessions, conversing with Karen’s extraordinary body of work across the history and theory of international law, gender and feminism studies, and private and foreign relations law. Four former HLM Lecturers will deliver these lectures in conversation with three discussants, all outstanding scholars mentored by Karen.

Session IV Discussion and Q&A led by Professor Susan Marks

Chair: Professor Antony Anghie

Professor Marks will lead the discussion of the three talks, teasing out cross-cutting themes and the enduring influence of Karen Knop’s scholarship across different fields of international law scholarship.

Susan Marks is Professor of International Law at the LSE.
