Fredrikke Egeberg (1815-1861) was a Norwegian pianist and composer. She was born in Christiania on 23 November 1815 to Westye Egeberg (1770–1830), a Danish immigrant and businessman, and Anna Sophie Muus (1775–1862). Her family became wealthy through her father's lumber company. Egeberg was the youngest of nine children and their only daughter.[1] She was the sister of Westye Martinus Egeberg and physician Christian Egeberg, and an aunt of Ferdinand Julian Egeberg, Einar Westye Egeberg, Sr. and Theodor Christian Egeberg. Violinist Ole Bull was a friend of the family and often played at the family chamber music concerts. Egeberg's brother, Christian, became an accomplished amateur cellist. Her two nieces, Anna Egeberg and Fredrikke Lindboe, also became composers of songs and piano pieces.
