Hammerich was active in the Danish Music Pedagogical Association (Dansk Musikpædagogisk Forening) and contributed to various journals.
[1][2][3] Born in Roskilde on 1 November 1854, Golla Andrea Bodenhoff Jensen was the daughter of the specialist physician Hans Peter Jensen (1818–95)[4] and his wife Golla Hermandine née Rosing Bodenhoff (1820–1906).
Although she continued to practice chamber music at home with prominent musicians, it was not until she was in her mid-thirties that she first appeared in public, soon becoming one of the country's leading pianists.
She gave concerts of works composed by women and published a collection of their songs.
In 1888, she appeared with the violinist Frederik Hilmer and the cellist Ernst Høeberg in a concert including music by the Russian composer Anton Arensky.
