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. Later the same year she played at the Gewandhaus in Leipzig, becoming a pupil of Franz Liszt in Weimar in 1873. In 1875 she was married to the celebrated singing teacher Herr Grondahl of Christiania, and 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.
