Neil's Bohr developed his model of the atom in 1931 as a student of Rutherford. This model suggested that electrons orbited in concentric circles around the nucleus at discrete energy levels.
He did not discover it. He just gave the structure of the Atom after a few other scienctists.
The atomic model of Bohr is from 1912.
Bohr
Dalton 'drew' the first atom, however, this was essentially a circle with a letter in it. The popular version of the atom, as seen today, was theorized by Rutherford.
He made a model of the atom, with electrons circling the nucleus.
Bohr devoleped a model of the atom that predicts how it will behave.
The Bohr model was made around 1913. There isn't an exact date, it's unknown.

Niels Bohr
Neils Bohr changed the current view of the atom by adding a nucleus with made up of protons and neutrons.
Niels Bohr's 1913 model was the first to depict the atom as small positively charged nucleus in the center with negative charged electrons circling around it, similar in shape to the solar system. Though quantum theory has made his model obsolete. it is a simple and good enough approximation it's still be taught today when introducing students to the atom.
Niels Bohr (the father, not the son who also got a Nobel prize) is n´known for: - Nuclear models with layers explaining radiation - Contributions to quantum mechanics - Politcal work after WWI to put the nuclear bomb under UN control
Dalton proposed planetary model. He kept electrons at a distance.
The atomic model of Bohr (1913) suppose that an atom is formed from a central electrically positive charged nucleus surrounded by electrically negative charged electrons moving on circular orbits.
Bohr's atomic model introduced some mechanical aspects to the atomic model, and, more importantly, it provided a theoretical frame for Rydberg's formula, which had been observed only empirically.
