Sophia Rosa Berghout (14 December 1909 - 22 March 1993) was a Dutch harpist.
[1][2] Her obituary in The Independent called her "arguably the most influential harpist this century".
[citation needed] She studied the harp at the Amsterdam Conservatoire with Rosa Spier [de].
[3] Together with Maria Korchinska (1895-1979) she established the International Harpweeks held at Queekhoven near Amsterdam in the 1960s; these developed into the World Harp Congress.
[3] Berghout married Johannes den Hertog, pianist and assistant conductor of the Amsterdam Concertgebouw: they divorced after a short time.
