Niels Henrik David Bohr was a Danish physicist and professor of physiology at the University of Copenhagen. The scientist made numerous significant contributions to the field of Quantum physics and was even a recipient of the 1922 Nobel Prize. J. Robert Oppenheimer knew and admired Bohr for his contributions to the field of physics and had wanted to employ some of his techniques in his own model for the atomic bomb.

According to his press notes, Oppenheimer described Niels Bohr as his chief advisor and one of the major minds behind the invention.
