Contributions of Abraham, Lorentz and Poincaré to Classical Theory of Electrons

Max Abraham, Hendrik Lorentz and Henri Poincare developed theories of electrons in the years following the discovery of electrons in cathode rays and in a component of the radiation from radioactive elements. The subjects covered in their theories include electrodynamics of moving particles, the origins of mass and implications for other fundamental forces. Highlights include electromagnetic mass, the stability of electrons, and experimental evidence for the dependence of relativistic mass on velocity.
