She was born in Grycksbo, just outside of Falun, on 30 January 1846 and died in Stockholm on 7 October 1916. Her surviving works are limited to songs, but she was also active as a writer and it is significant that she wrote the texts to her musical works. Amalia Hjelm is the older sister of the well-regarded composer Helena Munktell.
