Interesting facts about Schumann

Robert Alexander Schumann (1810 - 1856); German pianist and composer; was a leading figure in the Romantic period of Classical music. He was an idealistic champion for the purity of music and expression during a time when flashy virtuosity and "note-spinning" were competing for the attention of the middle-class audience.

Born in Zwickau as the son of a bookseller, he read much literature during his youth, aspiring to be a poet when he grew up. He begun to compose some small pieces at the age of seven, with the encouragement of his father. His interest in music was furthered after he attended a recital by the influential pianist Ignaz Moscheles and heard the music of Franz Schubert and Felix Mendelssohn.

After the death of his father in 1826, he went to Leipzig in 1828 to study law according to his mother's wishes, while secretly taking piano lessons with Friedrich Wieck. In 1830, he finally persuaded his mother to allow him to pursue the career of a pianist; and Wieck accepted him as a "live-in" student.

Sadly, in 1832, the third finger of his right hand became permanently injured, allegedly from use of a finger-strengthening device or an operation to separate the tendons of the third and fourth finger (it has also been suggested that the paralysis of his finger was due to a cure for syphilis). Therefore from then on, he had to abandon his career as a pianist and concentrate on composition and criticism.

In 1834, he founded the Neue Zeitschrift für Musik, one of the most influential periodical music journals of the day, which promoted promising composers  such as Frédéric Chopin and Hector Berlioz, while condemning the iconoclastic music of the Weimar School.

By 1835, he was deeply in love with Wieck's daughter, Clara, also an accomplished pianist. Wieck deeply disapproved of their blossoming romance and tried to separate them. After much legal argument, Robert and Clara finally obtained consent in 1840 from the court to marry without Wieck's permission. Until then Schumann had composed almost solely for the piano, however in 1840, his "year of song", he composed a stunning 168 songs, full of varying lyrical emotions said to be aroused by his love for Clara.

From 1840 - 1849, he ushered in a period of much productivity. Schumann, unlike many other composers, preferred to concentrate his creative energies on one compositional genre at a time. After his early period of focus on piano music and his "year of song", he composed two of his four symphonies in 1841, much of his chamber music was written in 1842 and 1843 was rather devoted to choral music.

From 1844, Schumann begun to suffer from depression, nervous breakdowns and bouts of shivering. He begun to imagine the note "A" sounding in his ear, and later that the ghosts of Schubert and Mendelssohn had sent him a theme (which was later developed into his 5 variations for the piano). Schumann had always feared the possibility of insanity, however in 1854, he threw himself into the Rhine river, only to be rescued by some boatmen, and was then declared to be quite mad.

As his mental health deteriorated, he was taken to an asylum in Endenich, near Bonn, where he spent the last few years of his life. It has been noted that the symptoms of his illness appear to match those of mercury poisoning; during that time mercury was commonly taken as a cure for syphilis.
