A few 20th century Black British scientists and innovators who broke barriers
Science plays an intrinsic role in society. Alton P Bell highlights Black scientists – past and present – whose work has had a lasting impact
Throughout the 20th century, British science saw remarkable contributions from Black scientists who advanced knowledge across mathematics, geology, anthropology, botany, brewing science, and more. Their achievements not only enriched their disciplines but also served as powerful testimonies of perseverance and excellence. Below, we spotlight five distinguished figures who made great strides in their particular discipline.
1. Professor Nira Chamberlain OBE: Mathematics and Industrial Modelling
Mathematician Nira Chamberlain is renowned for applying complex mathematical modelling to practical, real-world challenges. He developed the Mathematical Cost-Capability Trade-Off Model, which gave the UK government the necessary evidence to build the HMS Queen Elizabeth aircraft carrier. Chamberlain’s leadership in mathematics was recognised nationally: he was named one of the UK’s top scientists by the Science Council in 2014; voted the World’s Most Interesting Mathematician in 2018; and he served as President of the Institute of Mathematics and its Applications (IMA) from 2020 to 2022. Beyond academia, he is a prominent advocate for diversity in STEM.
2. Dr Raphael Armattoe (1913–1953): Medicine and Anthropology
Originally from the Gold Coast (now Ghana), Raphael Armattoe was trained in medicine in Edinburgh and later practised in Northern Ireland. He founded the Lomeshie Research Centre, blending medical science with cultural anthropology. Armattoe was invited to the Nobel ceremonies in 1947 – making him a rare African presence among global scholars – and was nominated for the Nobel Peace Prize in 1948 for his humanitarian and scientific contributions.
3. Sir Geoff Palmer (1940–2025): Grain Science, Brewing, and Human Rights
Born in Jamaica and arriving in Britain as part of the Windrush Generation, Sir Geoff Palmer became Scotland’s first Black university professor in 1989, ultimately serving as Professor Emeritus at Heriot-Watt University. His most notable scientific innovation was the barley abrasion process, developed in 1968. This technique radically improved malting efficiency by mechanically abrading barley grains, accelerating germination, and boosting extract yields – transforming the brewing and distilling industry worldwide. In 1998, he received the American Society of Brewing Chemists Award of Distinction – recognised as the ‘Nobel Prize of brewing’.
At Heriot-Watt, Palmer founded the International Centre for Brewing and Distilling (ICBD), elevating teaching and research in grain science to global prominence. His expertise extended into advisory roles for governments, particularly on sorghum as a brewing grain in Africa.
Alongside his scientific legacy, Palmer was a committed human rights activist and historian. He wrote extensively on Scotland’s colonial and slavery history, advocated for honest public commemoration, and campaigned for educational reform to address racial inequality. He was knighted in 2014 for services to human rights, science, and charity, later becoming Chancellor of Heriot-Watt University and a recipient of the Edinburgh Award for his anti-racism work.
4. Dr Melrose Stewart: Chartered Physiotherapist and Health Equity
Born in Jamaica, Dr Melrose later moved to the UK, where she qualified as a physiotherapist. She earned a master’s degree in education and a PhD for her research on cultural competence. Her work has focused on achieving equity in health and social care and promoting physical and mental well-being. She is a Vice President of the Chartered Society of Physiotherapy and has been involved in various other professional organisations. She also appeared on the Channel 4 programme Old People’s Home for 4 Year Olds, which further increased her visibility.
5. Dr Maggie Aderin-Pocock: Space Science and Communication
Born in London in 1968, Dr Maggie Aderin-Pocock is an esteemed space scientist and science educator. With degrees in physics and mechanical engineering from Imperial College London and a PhD in interferometry, she advanced astronomical instrumentation – such as a high-resolution spectrograph for the Gemini telescope – and contributed to climate research via satellite technology. Widely known for her work on the BBC’s The Sky at Night, she has inspired countless children through her outreach and was honoured with the Institute of Physics’ Lord Kelvin Medal – among other accolades.
All of these trailblazers redefined what was possible in their disciplines, often in the face of systemic obstacles. Through determination, innovation and advocacy, they not only advanced scientific frontiers but also created paths for future generations. Their legacies continue to remind us that excellence knows no boundaries.
