Johanne Fenger (September 5, 1836 – August 11, 1913) was a Danish composer.
Belonging to a family with many priests, doctors and officials, she was the daughter of the priest Johannes Ferdinand Fenger.
Johanne Fenger never had permanent employment.
Instead she lived together with her family her whole life, at first with her parents and later with other relatives.
Her father was acquainted with B.
S.
Ingemann.
She and her father performed for him with songs from other countries, which they recommended that he should translate to Danish.
Her father was given a new parish in Høje Tåstrup which meant that she was able to travel to Copenhagen by train to receive piano, singing and composition lessons from Leopold Rosenfeld and Edvard Helsted.
Her relative, the composer Christian Barnekow, was president of the Society for publication of Danish music.After her parents' death, Johanne Fenger lived with her uncle Carl Emil Fenger, a doctor and politician.
She probably tutored his children but taught choir, song and piano.
During this time she was victim to a stroke and became partially blind and started suffering from delusions.
Between 1885 and 1896 she was treated at a psychiatric hospital.
Later her sister Sofie took her home and eventually she became able to play music again.
