    "abstract": "We commemorate 50 years from A. Proca\u0027s death. Proca equation is a\nrelativistic wave equation for a massive spin-1 particle. The weak interaction\nis transmitted by such kind of vector bosons. Also vector fields are used to\ndescribe spin-1 mesons (e.g. $\\rho$ and $\\omega$ mesons). After a brief\nbiography, the paper presents an introduction into relativistic field theory,\nincluding Klein-Gordon, Dirac, and Maxwell fields, allowing to understand this\nscientific achievement and some consequences for the theory of strong\ninteractions as well as for Maxwell-Proca and Einstein-Proca theories. The\nmodern approach of the nonzero photon mass and the superluminal radiation field\nare also mentioned.",
