This led to the important discovery that rays emitted by cathodes (negatively charged electrodes) consisted of negatively charged particles called electrons. ... New Zealand-born British physicist Ernest Rutherford (1871-1937) discovered a positively charged subatomic particle, the proton, in 1919. He also predicted...

Basic Properties of Electrons ... William Crookes (1832-1919) discharged electricity through low pressure tubes and discovered cathode rays (electrons) ... He concluded that cathode rays are composed of negative corpuscles (electrons) which are present in all kinds of metals, and he determined the charge to mass (e/m) ratio...
