Gresham College Lectures

The lecture shares perspectives from global history, comparative politics, and international relations to revaluate whether the twentieth-century collapse of European colonialism was as definitive as often portrayed. It suggests that, while in some ways, ending European Empires remade our contemporary world, in others processes of decolonization are far from complete.

This lecture was recorded by Martin Thomas on the 9th of April 2025 at Barnard's Inn Hall, London

Martin is Professor of Imperial History and Director of the Centre for Histories of Violence and Conflict at the University of Exeter.

He was awarded a Philip Leverhulme prize for outstanding research in 2002 and has been both a Leverhulme Trust Research Fellow and a fellow of the Independent Social Research Foundation. He has also held visiting fellowships at Sciences Po., Saint-Germain-en-Laye, and the Netherlands Institute of Advanced Studies in Amsterdam.

Decolonisation movements sought to win sovereignty and control over national resources, especially oil. This lecture explores oil’s influence on national independence struggles, from the 1955 Bandung Conference to the rise of OPEC and the nationalisation of crude reserves. It examines how these shifts reshaped global power, exposing both the successes and limits of decolonisation, and their contemporary relevance to understanding the roots of today’s climate crisis.

This lecture was recorded by Adam Hanieh on the 15th of May 2025 at Barnard's Inn Hall, London

Shanawdithit was a woman who bore witness to the death of her world in the early nineteenth century, creating the only first-hand account we have of the Beothuk people from the Island of Newfoundland.  This lecture seeks to narrate the history of her fascinating and important life, alongside the history of her island, which was England’s first transatlantic colony. It will illuminate the profound connections between the hyper-extraction of the island’s resources, the hyper-exploitation of its settlers, and the violent and totalizing dispossession of Shanawdithit’s people. 

This lecture was recorded by Julia Laite on the 30th of April 2025 at Barnard's Inn Hall, London

Julia Laite is Professor of History at Birkbeck, University of London. 

Her most recent book The Disappearance of Lydia Harvey (2021) won the Golden Dagger for Non-Fiction from the British Crime Writer’s Association. She has published widely on the history of sexual labour, migration, and crime history, and works as a historical consultant in British media. Her new book project, A Woman at the End of the World, will tell the life story of the Beothuk woman Shanawdithit, the dilletante ethnographer William Eppes Cormack, and her own Newfoundland ancestors.

Health over the last 150 years in the UK and internationally has been transformed and this rapid rate of change will continue. Improvements in public health and the shifting demographic structure are altering the trajectory and frequency of disease. Advances in science including new drug classes, diagnostics and AI are changing what is possible in diagnosis and treatment. This lecture will consider the possible, and likely, direction of health over the next decades.

We perceive the world through the processing of information given by our senses. Sometimes, this processing is faulty leading to illusions: shapes or sounds that we perceive differently from their physical reality. These illusions have delighted children and scientists alike for centuries. This lecture reveals how simple geometric illusions can be modelled mathematically, based on our understanding on how visual signals are coded and decoded by the brain, leading to a better understanding of how we process information.

This lecture was recorded by Alain Goriely on the 17th of June 2025 at Barnard's Inn Hall, London.

Alain is Gresham Professor of Geometry.

He is currently the Director of the Oxford Centre for Industrial and Applied Mathematics and was elected as a Fellow of the Royal Society in 2022.

Our understanding of the human immune system today is vastly different from that of 50 years ago. This knowledge has led to immune-based therapies that would have seemed like science fiction to our grandparents: monoclonal antibodies, T-cell therapies, anti-cancer vaccines, precision immune suppression – the list is endless. In this lecture, we look to the future and ask, “What next for immunity?” 

This lecture was recorded by Robin May on the 11th of June 2025 at Barnard's Inn Hall, London.

He is also Chief Scientific Adviser at the Food Standards Agency (FSA) and Professor of Infectious Disease at the University of Birmingham.

This is the fifth and final lecture from the Gresham Festival of Musical Ideas.
https://www.gresham.ac.uk/watch-now/series/musical-ideas-2025

Professors Lintott and Mermikides present and discuss historical and contemporary musical representations of astronomical data including Pythagoras’s parallelism of tuning purity and celestial movement, Plato’s cosmic harmony in Timaeus, Kepler’s representations of orbital eccentricity as musical scales, Herschel’s blending of music and cosmology, and the tendency of stable planetary systems to ‘find’ harmonic ratios. The contemporary field of astro-sonification – using sound to represent, search and communicate to a diverse audience, astronomical patterns from black hole radiation to exoplanetary systems – is demonstrated with original examples.

This lecture was recorded by Milton Mermikides and Chris Lintott on 29th June 2025 at Barnard's Inn Hall, London.

Chris is Gresham Professor of Astronomy. He is also a Professor of Astrophysics at the University of Oxford, and a Research Fellow at New College. Milton Mermikides  is Gresham Professor of Music.He is Associate Professor in Music at the University of Surrey, Professor of Guitar at the Royal College of Music and Deputy Director of the International Guitar Research Centre.
