Electron: Johann Wilhelm Hittorf in 1869 got the first observations of cathode rays. and in 1876, Eugen Goldstein showed that the rays from this glow cast a shadow. He called them Cathode Rays.
In 1896 J. J. Thomson, with his colleagues John S. Townsend and H. A. Wilson, performed experiments that showed that cathode rays were actually unique particles. 
Rutherford and Bequerel later showed that radioactive materials emitted negative particles (called beta particles) which were found to be electrons.
The charge of the electron was determined by Robert Millikan and Harvey Fletcher in 1909 using the so-called Oil Drop Experiment.

siril: discovered, because 'invented' is a lot different
