Elfrida Andrée was a Swedish organist, composer, and conductor.
An activist in the Swedish women’s movement, she was one of the first female organists to be officially appointed in Scandinavia. She began work in Stockholm in 1861 and became the organist at Gothenburg Cathedral in 1867. For her services, she was elected to the Royal Swedish Academy of Music.
Andrée’s two organ symphonies are still performed today. Her other compositions included the opera Fritiofs saga, several works for orchestra including two symphonies, a piano quartet in A minor and a piano quintet in E minor, a piano trio in G minor, and another published posthumously in C minor, string quartets in D minor and A major, pieces for violin and for piano, two masses, a choral ballade “Snöfrid,” and lieder.
