Musik-Lexikon. Theorie und Geschichte der Musik, die Tonkünstler alter und neuer Zeit mit Angabe ihrer Werke, nebst einer vollständigen Instrumentenkunde

Hugo Riemann's fondness for controversial musicological theories got him into trouble at a surprisingly early age: he completed a complex doctoral dissertation at 23 only to have it rejected by the University of Leipzig. Gaining support from like-minded musicologists in who were better positioned to upset apple carts, Riemann was hired for a number of teaching posts; the last of these, ironically, was at Leipzig, where he was named a professor in 1901.
