For 10 points, identify this namesake of an orbit-based atomic model who hailed from Denmark.
This man is the namesake of a constant, symbolized mu-sub-B, which serves as the unit of the electron magnetic dipole moment. He believed that quantum mechanics described only probabilities and must be explained in the terms of classical mechanics. This namesake of a "magneton" and formulator of the complementarity principle was central to theorizing the Copenhagen interpretation and created a model that explained the emission lines of hydrogen.
