The plum pudding model is an obsolete scientific model of the atom. It was first proposed by J. J. Thomson in 1904 [1] following his discovery of the electron in 1897 and subsequently rendered obsolete by Ernest Rutherford 's discovery of the atomic nucleus in 1911. It was the first model to describe an internal structure for the atom.
Sir Joseph John Thomson OM FRS [1] (18 December 1856 – 30 August 1940) was a British physicist and Nobel Laureate in Physics, credited with the discovery of the electron, the first subatomic particle to be found.

The experiments were performed between 1906 and 1913 by Hans Geiger and Ernest Marsden under the direction of Ernest Rutherford at the Physical Laboratories of the University of Manchester. The most crucial of these experiments was performed in 1909, being the one where they discovered angles of scattering greater than 90 degrees.
