From the Darkness of Occupation to the Light of Mass: The Englert-Brout Tandem,A Journey of Perseverance

This article explores the extraordinary life of Nobel Laureate Fran¸cois Englert, tracing his
path from the perils of the Holocaust in occupied Belgium to the pinnacle of theoretical
physics. It examines his pivotal partnership with the American physicist Robert Brout,
a collaboration that began at Cornell and flourished at the Universit´e Libre de Bruxelles
(ULB). We provide a complete mathematical treatment of their 1964 discovery—the mech
anism of Spontaneous Symmetry Breaking in gauge theories—which solved the problem of
mass for gauge vector mesons. Furthermore, we analyse the historical sociology of science
that led to the moniker “Higgs boson,” overshadowing the priority of the Belgian duo, and
conclude with the legacy of their work in the Standard Model and the historic 2012 discovery
at CERN.
