discovered electrons
The Electron Cloud theory was proposed in the early 20th century, around the 1920s. It was developed as an improvement to the Bohr model of the atom to better describe the behavior of electrons within an atom.
JJ Thomson called his model of the atom the "plum pudding model." In this model, electrons were embedded in a positively charged sphere, resembling the distribution of plums within a British pudding dessert.
John Dalton's atomic theory indicated that atoms were indivisible spheres. When JJ Thomson did his work with cathode ray tubes, he discovered that atoms contain electrons, which meant that the atom is not indivisible, that there are smaller particles within.
JJ Thomson's model of the atom is called the "plum pudding model." It suggested that atoms were made up of positive and negative charges distributed throughout a neutral, positively-charged background.
here are some jot notes about thomasons theory: 1894+ +ve sphere with embedded electrons net charge of 0 no protons no neutrons his theory led to the "Plum-Pudding "model

he is still alive.
JJ Thomson used a cathode ray tube in his atomic theory experiment, known as the cathode ray experiment. By observing the behavior of cathode rays in the tube, he was able to discover the existence of electrons and propose the plum pudding model of the atom.

I'm pretty sure it was jj. Thompson but i coudnt be sure
