The Belgian Group of Rheology is deeply saddened to announce the passing of our most distinguished member and cofounder, Professor Jan Mewis, on December 14th, 2025. It is with profound grief that we share this loss with the global rheology community. Professor Mewis was not only one of the world’s most eminent rheologists — having received, among many honors, the Bingham Medal and the Gold Medal of the British Society of Rheology — but also an exceptional mentor who generously shaped generations of scientists through his insight, kindness, and unwavering dedication to the field.
His scientific legacy and personal influence will endure, and he will be remembered with deep respect, gratitude, and affection by colleagues, students, and friends worldwide.
