he was a British scientists that discovered negatively charged particles, electrons, inside the atom. he proposed a possible structure of the atom (atomic model) called the plum pudding. you can Google some images

J. J. Thomson discovered the electron (particle carrying negative charge) in 1897.
Millikan found the charge of an electron by his famous oil drop experiment. J J Thomson determined the specific charge of the electron. That means the ratio of the charge of an electron to its mass. With these two values one can find the mass of electron by dividing the charge value by its specific charge.
