{geni:about_me} Probably same as the reference in "David Popper" by Stephen De'ak: "Caroline Brandeis...Well-known Prague pianist... David Popper took her under his wings...presenting her... introduced her in Budapest"

David Popper mentions his niece Camilla Brandeis explicitly in his will.

Deutsches Musiker-Lexikon (Herausgegeben von Erich H. Muller, Dresden: Wilhelm Limpert, 1929, 1644 p.) has Camilla Brandeis, Pianist, born 24 Aug 1878 in Prague"
