Robert Schumann (; 8 June 1810 - 29 July 1856) was a German composer and an 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. He had been assured by his teacher Friedrich Wieck, a German pianist, that he could become the finest pianist in Europe, but a hand injury ended this dream.
1830-34
During Eastertide 1830, he heard the Italian violinist, violist, guitarist, and composer Niccolo Paganini play in Frankfurt. In July he wrote to his mother, "My whole life has been a struggle between Poetry and Prose, or call it Music and Law." By Christmas he was back in Leipzig, at age 20 taking piano lessons from his old master Friedrich Wieck, who assured him that he would be a successful concert pianist after a few years' study with him.  During his studies with Wieck, it has been claimed that Schumann permanently injured a finger on his right hand. Wieck claimed that Schumann damaged his finger by the use of a mechanical device designed to strengthen the weakest fingers, a device which held back one finger while he exercised the others. This claim has been discredited by Clara Schumann, who said that the disability was not due to a mechanical device, and Robert Schumann himself refers to it as "an affliction of the whole hand". Some have argued that, as the disability appeared to have been chronic and have affected the hand, and not just a finger, it was unlikely to have been caused by a finger strengthening device.  Schumann abandoned the idea of a concert career and devoted himself instead to composition. To this end he began a study of music theory under Heinrich Dorn, a German composer six years his senior and, at that time, conductor of the Leipzig Opera. About this time Schumann considered composing an opera on the subject of Hamlet.
