François Englert was a renowned Belgian theoretical physicist celebrated for his groundbreaking work in particle physics. He played a crucial role in the development of the theoretical framework that explains how particles acquire mass. His research, alongside Peter Higgs, led to the formulation of the Higgs mechanism, which is fundamental to the Standard Model of particle physics. Englert's contributions significantly advanced our understanding of the universe at the smallest scales. His work helped explain the origin of mass for elementary particles, a discovery that was confirmed through experiments at CERN. This achievement earned him and Higgs the Nobel Prize in Physics in 2013, highlighting the importance of their theoretical insights. Throughout his career, Francois Englert was respected not only for his scientific genius but also for his dedication to education and research. He mentored many students and colleagues, fostering progress in theoretical physics. His legacy continues to influence the field, and his contributions remain foundational to modern particle physics.
