Prof Hendrik Swart of the University of the Free State (UFS) has been awarded the 2026 South African Institute of Physics (SAIP) De Beers Gold Medal – the highest honour bestowed by the institute – in recognition of a distinguished career spanning more than four decades of advancing physics through internationally recognised research, scientific leadership, mentorship, and the development of research capacity in South Africa.

The award was announced during the gala dinner at the 70th Annual Conference of the South African Institute of Physics, held at the University of the Western Cape on Friday 10 July 2026.

Awarded every second year, the SAIP De Beers Gold Medal recognises outstanding lifetime achievement in physics through excellence in research, education, technology, and industrial development. Widely regarded as South Africa’s premier recognition in the discipline, it honours physicists whose sustained contributions have advanced both scientific knowledge and the broader physics community.

Prof Swart was recognised for his internationally influential work in luminescent and photonic materials, solid-state physics and advanced functional materials, optical spectroscopy and materials characterisation, as well as for building world-class research infrastructure, mentoring postgraduate students and postdoctoral researchers, and strengthening South Africa’s international standing in materials physics through extensive global collaborations.

Congratulating Prof Swart on the achievement, Prof Hester C. Klopper, Vice-Chancellor and Principal of the UFS, said: “Congratulations! This is excellent news and speaks to your contribution over many years. We salute you!”

Prof Vasu Reddy, Deputy Vice-Chancellor: Research, Innovation and Postgraduate Studies, echoed the views expressed by the vice-chancellor, stating: “Congratulations to Prof Hendrik Swart on receiving the 2026 SAIP De Beers Gold Medal – an exceptional recognition of a lifetime dedicated to advancing physics, research excellence, and scientific leadership in South Africa and globally. Prof Swart’s distinguished career reminds us that science is not only about discovery. It is about creating knowledge that improves lives, advances society, and inspires future generations of researchers and innovators.”

A lifetime of advancing physics

Receiving the award, Prof Swart says, is both humbling and deeply meaningful. “It is one of the greatest honours of my academic career to receive the 2026 SAIP De Beers Gold Medal. As the highest honour bestowed by the South African Institute of Physics, it is a testament to my colleagues’ appreciation of my many years of commitment to advancing physics through scientific leadership, mentoring, teaching, and research,” he says.

“Receiving this honour makes me feel incredibly humbled and appreciative. Even though the medal is given to a single person, I see it as a testament to the combined efforts of numerous individuals who have helped me along the way. I have had the honour of working with outstanding coworkers, bright postgraduate students, postdoctoral fellows, and international partners who share my enthusiasm for scientific advancement.”

Prof Swart also credits the National Research Foundation, the University of the Free State, and numerous funding partners for creating an environment that supports globally competitive research. While the award bears his name, he says it is one he also dedicates to his wife, children, and grandchildren.

Over the course of his career, Prof Swart has established himself as one of South Africa’s leading materials physicists. An NRF B1-rated researcher, he has authored or co-authored more than 1 000 peer-reviewed journal articles, more than 120 conference proceedings, and approximately 100 books and book chapters. His work has attracted more than 34 750 citations, while his research leadership includes the South African Research Chairs Initiative (SARChI) Chair in Solid State Luminescent and Advanced Materials, first awarded in 2012 and renewed in both 2017 and 2022.

Beyond his own research, he established the National Nanosurface Characterisation Facility at the UFS, providing researchers from across South Africa with access to world-class materials characterisation infrastructure. During his career, he has also supervised more than 120 master’s and doctoral graduates, many of whom have gone on to successful careers in academia, research institutions, and industry.

Building a legacy through science and mentorship

Despite an extraordinary list of scientific achievements, Prof Swart says his greatest source of pride is the research environment he has helped build and the people who have grown through it.

“Looking back, I am proud not only of the scientific contributions we have made, but also of the lasting research environment we have built at the University of the Free State. Together with several colleagues, we have created a world-class research infrastructure that facilitates the characterisation of cutting-edge materials and established internationally recognised research programmes in luminescent and advanced materials.”

For him, however, the true measure of success is not the number of publications or citations, but the next generation of scientists.

“Seeing previous students and postdoctoral fellows pursue prosperous careers in academia, business, and research organisations across South Africa and the world is, perhaps, what gives me the most happiness. It is significantly more satisfying to see young researchers grow into scientists, leaders, and supervisors than any one paper or citation.”

This philosophy also shapes his approach to mentorship.

“Scientific knowledge only has lasting value when it is passed on to the next generation. For me, mentoring students and early-career researchers has always been one of the most rewarding aspects of being an academic.”

He believes that developing independent thinkers is essential to South Africa's scientific future, adding that supporting young researchers to become problem-solvers and future leaders remains one of his greatest motivations.

Research that improves everyday life

Although Prof Swart’s research focuses on highly specialised materials physics, its impact extends far beyond the laboratory.

His work explores how materials interact with light and how those properties can be used to develop technologies that improve everyday life. Applications include LED lighting, television and smartphone displays, medical imaging, radiation detectors, temperature sensors, renewable energy technologies, environmental monitoring systems, and security features used in banknotes.

“While the science can be highly sophisticated, the goal is straightforward: to create materials that address real-world challenges and contribute to technological innovation and sustainable development,” he explains.

His research has played a leading role in advancing luminescent and advanced functional materials, helping to position both the UFS and South Africa among internationally recognised contributors in the field of materials physics.

Science without borders

International collaboration has been central to Prof Swart’s research journey.

Over many years, he has built partnerships with leading universities and research institutes across Europe, Asia, North America, and Africa. These collaborations have provided access to specialised facilities, supported joint supervision of postgraduate students, enabled researcher exchanges, and produced numerous high-impact scientific publications.

“I believe these partnerships have increased the University of the Free State’s international visibility and demonstrated that South African researchers can make meaningful contributions to the global scientific community,” he says.

He adds that international partnerships have also created valuable opportunities for postgraduate students and postdoctoral researchers to gain global experience before bringing new knowledge, skills, and research approaches back to South Africa.

For Prof Swart, however, the award is not only recognition of a lifetime of scientific excellence, but also of the many people who have shared the journey. While the medal honours an individual, he regards it as a celebration of the colleagues, students, collaborators, funding partners, and family whose support has helped shape one of South Africa’s most distinguished careers in physics.
