Einstein's work on the special and general theories was based on the work of predecessors and contemporaries, Maxwell, Michelson-Morley, Minkowski, Poincare, Mach, Dirac, Lorentz, Friedmann, Hilbert, Bose, Bohr, Schrodinger, Szilard, Posner, Podolsky, Freundlich, Grossman, Noether, and Olinto De Pretto, who first published the equation e=Mc^2.
The field equations of relativity are in fact Hilbert's field equations with some additions.

His work on light led him to propose the stimulated emission of radiation, which we now know as light amplification by stimulated emission of radiation. Or Laser.
"In 1917, Einstein published an article in Physikalische Zeitschrift that proposed the possibility of stimulated emission, the physical technique that makes possible the laser (Einstein 1917b). " |
