James Dalton is best known for his pioneering work in the development of modern atomic theory.
Eugen Goldstein discovered canal waves, and is sometimes credited with discovery of a proton.
He is credited with discovering electrons and isotopes.
Robert Millikan was aNobel laureate in physics for his measurement of the charge on the electron and for his work on the photoelectric effect.
Rutherford discovered the concept of radioactive half-life and he theorized that atoms have their charge concentrated in a very small nucleus.
Henry Moseley determined the number of positive charges in neutrons and developed the concept of the atomic number.
Neils Bohr created the Bohr model of an atom in 1915
Max Planck originated the quantum theory, which won him the Nobel Prize in Physics in 1918.
Einstein is credited for his discovery of the law of the photoelectric effect. This was pivotal in establishing quantum theory.
He developed a number of fundamental results in the field of quantum theory, and he also formulated the wave equation.
Louis deBroglie postulated the wave nature of electrons, one of the basis of the quantum physics.
