Robert Schumann (German: [ˈʃuːman]; 8 June 1810 – 29 July 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, after a long and acrimonious legal battle with Wieck, who opposed the marriage, Schumann married Wieck's daughter Clara. Before their marriage, Clara—also a composer—had substantially supported her father through her considerable career as a pianist. Together, Clara and Robert encouraged, and maintained a close relationship with, German composer Johannes Brahms.
Until 1840, Schumann wrote exclusively for the piano. Later, he composed piano and orchestral works, many Lieder (songs for voice and piano). He composed four symphonies, one opera, and other orchestral, choral, and chamber works. His best-known works include Carnaval, Symphonic Studies, Kinderszenen, Kreisleriana, and the Fantasie in C. His writings about music appeared mostly in the Neue Zeitschrift für Musik (New Journal for Music), a Leipzig-based publication that he co-founded.
Schumann suffered from a mental disorder that first manifested in 1833 as a severe melancholic depressive episode—which recurred several times alternating with phases of "exaltation" and increasingly also delusional ideas of being poisoned or threatened with metallic items. After a suicide attempt in 1854, Schumann was admitted at his own request to a mental asylum in Endenich near Bonn. Diagnosed with psychotic melancholia, he died two years later at the age of 46 without recovering from his mental illness.
