He studies in K\u00F6nigsberg, where he gains his doctorate in mathematics in 1891. He is influenced above all by his subsequent time as assistant to Felix Klein in G\u00F6ttingen. In 1900 he is appointed professor of technical mechanics at the Technical University of Aachen, and full professor of theoretical physics at the University of Munich in 1906. He starts incorporating Einstein\u2019s special theory of relativity into his lectures as early as 1907, and writes important articles on refining its mathematical formalism. He is among the early supporters of the quantum hypothesis and further develops the Bohr model of the atom. Sommerfeld\u2019s fundamental works include his 1919 treatise Atomic Structure and Spectral Lines, that is regarded as the \u201Cbible\u201D of atomic physicists at that time.
