Hermann Keller (20 November 1885 – 17 August 1967) was a German Protestant church musician and musicologist.
[1] Max Reger, with whom Keller took private lessons, advised him to make music his profession.
After the Second World War, he was director of the State University of Music and Performing Arts Stuttgart (1946-1952) and was significantly involved in its reconstruction.
At the beginning of the 20th century, he published organ works and performed mainly Bach as docent and interpreter not only in Europe but also in the USA and Japan.
Through his long-standing collaboration with the Leipzig and Frankfurt publishers "Peters" he became a bridge-builder between the two post-war German states.
