The proton was discovered in 1918 by Ernest Rutherford. He noticed that when alpha particles were shot into nitrogen gas, his scintillation detectors showed the signatures of hydrogen nuclei. Rutherford determined that the only place this hydrogen could have come from was the nitrogen, and therefore nitrogen must contain hydrogen nuclei. He thus suggested that the hydrogen nucleus, which was known to have an atomic number of 1, was an elementary particle. This he named proton, from protos, the Greek for "first".

Discovery of the ProtonIn the early 1920's after the discovery of the electron, Rutherford and other physicists made a number experiments, transmuting one atom into another. In every case, hydrogen nuclei were emitted in the process. It was apparent that the hydrogen nucleus played a fundamental role in atomic structure, and by the late 1920's physicists were regularly referring to hydrogen nuclei as 'protons'. The term proton itself seems to have been coined by Rutherford, and first appears in print in 1920.See the Related Questions links to the left for more information.

Discovery of the proton happened so slowly and by so many that it is impossible to give just one scientist credit for it. Physicists Rutherford, who is credited with discovering the nucleus, is also credited with coining the name proton.
The electron was discovered by J.J. Thompson. Simply, he used a Cathode ray tube and magnetic fields to "bent" the flow of particles. He also determined the mass to charge ratio of the electron, thus proving it to be less massive (and a component) of the atom. By extension, as electrons were negative and matter is generally neutral, he knew that there must be something positive inside the atom to balance the charge. He came up with the plumb pudding model of the atom. The proton was discovered by Ernest Rutherford. He bombarded a sheet of gold foil with alpha particles, and found that the majority of these particles passed through (thus disproving the plumb pudding model) while very few were radically deflected or reflected. The neutron was discovered by James Chadwick. His experiment was a variation on that used by Irene Curie and her husband involving polonium and alpha radiation. The discovery of each of the three basic particles that make up the atom is take up by three separate questions - one for each one. All there questions are listed in the related questions area below, and they are links to those questions.
