Chopin arrived in Paris in 1831, and there he knew important people of the literary and artistic world such as the writer George Sand -she and Chopin had a brief and intense romance-, the musician Franz Liszt, the poet Heinrich Heine and the painter Eugène Delacroix.

At the end of 1831, his work was recommended, and recognized as ‘‘a genius’’ by the well-known musician Robert Schumann. In 1832 he made his debut in Paris with a wonderful concert, which was celebrated by the critic François-Joseph Fétis.
