Who discovered the Electron?

The electron was discovered by J.J. Thomson, a British physicist, in 1897. Thomson was conducting experiments with cathode rays inside a vacuum tube, similar to the ones used in early television sets. He observed that these rays could be deflected by electric and magnetic fields in a manner that was consistent with them being made up of negatively charged particles. Thomson called these particles “corpuscles,” but they were later named electrons. His discovery of the electron revolutionized our understanding of atomic structure and laid the foundation for the field of particle physics.
