Ernest Rutherford: born on August 30, 1871, and died on October 19, 1937
The picture below is a model of Rutherford's atom. This picture shows the nucleus of a atom, and electrons. The negatively charged electrons elliptically orbit around the positively charged nucleus. His model of the atom has been said to resemble a mini solar system!
Rutherford's experiment, the gold foil experient, was a radioactive source of positively charged heavy particles inside a thick lead box with a narrow opening. The particles were distributed in narrow beams by passing them through a lead sheet through a slit. An extremely thin piece of gold foil was hit with the narrow beam of fast moving particles which was veiwed through florecence microscope. The experiment was setup inside a chamber so air particles wouldn't interfear. Rutherford created this experiment in response to Thomsons Plum Pudding experiment!
