Atomic Model
Created his own version of the atomic model. Before this, Ernest Rutherford had specified atoms as a central positive nucleus surrounded by negative electrons orbiting it. Bohr, finding this to be an unstable description, set out to formulate his own theory about the orbital paths of electrons and the cause of electromagnetic radiation.

Saving Science
Bohr felt the impact of Germany's conversion to Nazism when he saw that Jewish physicists had been put out of a job because of the new regime. Reaching out, he made contact with other foundations to find those physicists a temporary place to stay at Bohr's institute before they were relocated to more permanent places of residence. -
Nuclear Physics
Realizing that the study of theoretical physics centers around the nucleus of an atom as opposed to the entire atom, Bohr collaborated with the Rockefeller Center to build an early version of the particle accelerator, known as a cyclotron. Knowing irradiation of elements was a big deal, he had a wing designated for housing a cyclotron, the completion date of which being the year listed. -
Lasting Legacy
After being stranded for several years, he was finally able to return to his home after the nuking of Japan in August of 1945. Upon his return, he went back to his work as a physicist. He was involved in the foundation of two major scientific institutions, but the matter that preoccupied him the most was the "open world" that nuclear weaponry presented.
