Robert Schumann (1810-1856) was a German composer, pianist, and influential music critic. He is widely regarded as one of the greatest composers of the Romantic era. Schumann left the study of law, intending to pursue a career as a virtuoso pianist. His teacher, Friedrich Wieck, a German pianist, had assured him that he could become the finest pianist in Europe, but a hand injury ended this dream. Schumann then focused his musical energies on composing. In 1840, Schumann married Clara Wieck, after a long and acrimonious legal battle with her father, Friedrich, who opposed the marriage. A lifelong partnership in music began, as Clara herself was an established pianist and music prodigy. Until 1840, Schumann wrote exclusively for the piano. Later, he composed piano and orchestral works, and many Lieder (songs for voice and piano). He composed four symphonies, one opera, and other orchestral, choral, and chamber works. Schumann suffered from a mental disorder that first manifested in 1833 as a severe melancholic depressive episode. After a suicide attempt in 1854, Schumann was admitted at his own request to a mental asylum in Endenich (now in Bonn).
