The nucleus was discovered by Ernest Rutherford in 1914 with his famous gold foil experiment. From the results of shooting alpha particles (radiation) at a sheet of gold foil he determined that the atom must be made of mostly empty space with a dense, positively charged center called the nucleus.
This was the official discovery, though really Robert brown originally discovered the nucleus of a cell.

So they proposed different atom models. Then after the famous alpha particle scattering experiement the idea about the nucleus was introduced by Ernest Rutherford in 1909-1911.
