Upon completing her studies, Marx undertook a series of concert tours through France and Belgium, everywhere meeting with a cordial reception. At
Brussels, she met
Pablo de Sarasate, who, recognizing her great talent, engaged her as soloist and accompanist, in which capacities she accompanied him on his tours through Europe, Mexico, and the US; she played in all in about 600 concerts. She composed several "Rhapsodies Espagnoles," and arranged Sarasate's
Spanish Dances for the piano. Around 1894, she married Otto Goldschmidt, Sarasate's friend, accompanist, and manager. Marx accomplished some large memorizing feats in the course of her career. Perhaps the greatest occurred in 1894, when she played about 250 works by heart, during a series of concerts in Berlin and Paris. She died in 1925. ==References==
