Kurt Johnen (3 January 1884 – 26 February 1965) was a German pianist, music educator and musicologist.
Born in Burtscheid, Johnen attended the Gymnasium in Aachen[1] and studied musicology at the Humboldt-Universität zu Berlin and piano with Rudolf Maria Breithaupt from 1904 .
From 1908 until 1911, he was assistant of Rudolf Maria Breithaupt and studied at the Berlin University of the Arts.
In his scientific work, he was mainly concerned with occupational diseases of pianists, the psychology of music and especially with the connection between rhythm and phrasing and physiological processes such as breathing and pulse.
From 1952, he had a lectureship for music at the Staatliche Hochschule für Theater und Musik Halle [de] and from 1955 a teaching position for the treatment of professionally ill pianists at the Hochschule für Musik "Hanns Eisler".
