Agathe Ursula Backer Grøndahl (1 December 1847 – 4 June 1907) was a Norwegian pianist and composer. Her son Fridtjof Backer-Grøndahl (1885–1959) was also a pianist and composer, who promoted his mother's compositions in his concerts. Biography 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. Between 1865 and 1867 she became a pupil of Theodor Kullak and studied composition under Richard Wuerst at the Akademie der Tonkunst in Berlin, where she lived together with her sister Harriet Backer. She won fame there with her interpretation of Beethoven's "Emperor" Concerto. After her arrival to Norway in 1868, she debuted with Edvard Grieg, then 26 years old, as conductor of the Philharmonic Society. A recommendation from Ole Bull led to further studies with Hans von Bülow in Florence in 1871.

After that she was proclaimed one of the century's greatest piano artists by George Bernard Shaw, who also remarked on the sensitiveness, symmetry and artistic economy of her compositions.
