Victoria Bachke (7 July 1896 – 19 November 1963) was a Russian born, Norwegian musician and museum director.
In March 1914, Victoria and her elder sister Valentine Rostin (1887-1940) toured Europe.
Valentine Rostin became the new prima donna at Trondheim's theater after the role of Violetta in the play La Traviata.
The couple lived at Ringve Manor and assembled a large collection of historical musical instruments.
The museum principally displays the former private collection of Christian and Victoria Bachke.
