Abert stayed on at Halle as a lecturer, becoming a senior lecturer (or associate professor) in 1910 and a full professor in 1918. In this capacity he moved the next year to the University of Heidelberg. But after just one year, Abert took up a post at Leipzig and in 1920 he became the successor of the music theorist Hugo Riemann. In 1923 he was called to the University of Berlin, where he was seen as the most suitable successor to Hermann Kretzschmar, also a music theorist. It was there that he worked with Friedrich Blume, Rudolf Gerber, Hans Hoffmann and Theodor Schwartzkopff, on the illustrated Dictionary of Music which was discovered to contain plagiarisms of Alfred Einstein's Neues Musiklexikon und Hugo Riemann Musiklexikon.[1]
In 1925 he was admitted to the Prussian Academy of Sciences, the first music theorist to be granted this honour.
On 13 August 1927, Prof. Dr. Hermann Abert died at Stuttgart, aged 56.
