Biography
Early life
Agathe Ursula Backer was born in Holmestrand in 1847, in a wealthy and art-loving home, as the second youngest of four sisters, all gifted in drawing and music. In 1857, she moved with her family to Christiania, where she studied with Otto Winther-Hjelm, Halfdan Kjerulf and Ludvig Mathias Lindeman. She won fame there with her interpretation of Beethoven's "Emperor" Concerto.
Her parents heavily discouraged her performance career, believing it was unsuitable for a woman. They believed she was better suited to life as a house-wife. In a letter to Kjerrulf, she wrote, “I do not understand how both you and my parents could object to the fact that I want to become what one calls a female artist… It seems to me that a beautiful, independent future for a woman can be found in the simple act of striving, if possible, to be able to present an enjoyable experience to people, especially if that future included a way to travel and see a little of the world! But time will decide. I just feel that there is something in me that will never give me peace… for I love art so much that the desire to master it is indescribable.”
Return to Norway
After returning to Norway in 1868, she debuted in Christiania with the Philharmonic Society, playing the "Emperor" Concerto under the direction of Edvard Grieg, then 26 years old. Later the same year she played at the Gewandhaus in Leipzig, becoming a pupil of Franz Liszt in Weimar in 1873. During the second half of the 1870s she built up an outstanding pianist career with a series of concerts in the Nordic countries, also playing with very great success in London and Paris.
