Crookes observed that the cathodic rays are deflected by a magnetic field and concluded that this beam is negatively charged. Thomson established that the beam is composed from a new type of particles called by Fitzgerald electrons. But many scientists contributed to the discovery of the electron.

What particle did J. J. Thomson discover?
according to jj thomsons model of an atom,an atom consists of a positively charged sphere with electrons in it.however,it was later found that positively charged particles reside at the center of the atom called nucleus,and the electrons revolve around the nucleus.
Who first postulated the existence of the electron?
Good ol' J. J. Thomson my man. Using cathode rays
What type of charge do electrons have?
The charge of an electron is -1, and has a smaller mass of a proton. (For you Castle Learning users) :]negative chargeAn electron carries one fundamental unit of negative charge*, measured to be about 1.609 x 10-19 Coulombs.(* The negative designation is a convention, established in the earliest experiments with electricity long before the existence of the electron was known.)A proton has a +1 charge.A neutron does not have a charge, it is neutral.
