In Memoriam: Peter Higgs (1929-2024)

Peter Higgs was a British theoretical physicist, famous for his work published in 1964, where he proposed a mechanism that can generate masses for elementary particles, while respecting gauge invariance. Half a century later, two experiments at CERN confirmed that this mechanism is realized in nature. On April 8th, we received the sad news of the passing of the great pioneer of elementary particle physics. This article is dedicated to his memory, and to the mechanism and particle that bear his name. -- Peter Higgs fue un f\'isico te\'orico brit\'anico, famoso por su trabajo de 1964 donde propuso un mecanismo que puede generar masas para part\'iculas elementales, conforme a la simetr\'ia de norma. Medio siglo m\'as tarde, dos experimentos del CERN confirmaron que este mecanismo est\'a realizado en la naturaleza. El 8 de abril nos lleg\'o la triste noticia del fallecimiento del gran pionero de la fisica de part\'iculas elementales. Este art\'iculo es dedicado a su memoria, as\'i como al mecanismo y a la part\'icula que llevan su nombre.
