Less of a household name than colleagues such as Albert Einstein, Niels Bohr nevertheless contributed immensely to the developments of twentieth-century physics. Building on the work of his mentor Ernest Rutherford, Bohr developed his own atomic model that clarified and expanded the field of quantum theory.ess of a household name than colleagues such as Albert Einstein, Niels Bohr nevertheless contributed immensely to the developments of twentieth-century physics.
