Robert Schumann was a German composer 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. He had been assured by his teacher Friedrich Wieck that he could become the finest pianist in Europe, but a hand injury ended this dream. Schumann then focused his musical energies on composing.
Schumann's published compositions were written exclusively for the piano until 1840; he later composed works for piano and orchestra; many Lieder (songs for voice and piano); four symphonies; an opera; and other orchestral, choral, and chamber works. Works such as Carnaval, Symphonic Studies, Kinderszenen, Kreisleriana, and the Fantasie in C are among his most famous. His writings about music appeared mostly in the Neue Zeitschrift für Musik (New Journal for Music), a Leipzig-based publication which he jointly founded.
In 1840, Schumann married Friedrich Wieck's daughter Clara, against the wishes of her father, following a long and acrimonious legal battle, which found in favour of Clara and Robert. Clara also composed music and had a considerable concert career as a pianist, the earnings from which, before her marriage, formed a substantial part of her father's fortune.
Schumann suffered from a mental disorder, first manifesting itself 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 to a mental asylum, at his own request, in Endenich near Bonn. Diagnosed with "psychotic melancholia", Schumann died two years later in 1856 without having recovered from his mental illness.

Frédéric Chopin is one of the greatest composers of the Romantic piano tradition. He was a master in making the small form great. His ballades, mazurkas, polonaises, preludes, etudes and nocturnes all belong to the most popular standard works for piano ever written. As a child prodigy, Chopin grew up in a middle class family, who lived among the literati of Warsaw. When in 1830 the November Uprising broke out in Poland, the twenty year old Chopin stayed in Vienna. He became an exile and never returned to his mother country. He eventually settled in Paris. He avoided public concerts, but he did like performing in small settings, such as salons and at home for his friends. This way, Chopin built a reputation as an exceptional pianist, teacher and composer.
Chopin brought a unique synthesis between the Viennese bravado and the French/English lyric style. Even though his pieces often are technically very demanding, the focus was always on creating a lyric expression and poetic atmosphere. He invented the instrumental ballade, and brought salongenres to a higher level with his many innovations and refinements.

César Franck was simultaneously a child prodigy and a late bloomer. His parents quickly discovered his enormous talent, but they were mostly interested in the money and fame that he might generate. Because of this, he was presented as a piano virtuoso, without a focus on composition. Unfortunately, his virtuoso career was less promising then they had hoped, and he started earning his money more as a teacher and organist. Composing stayed in the background, but in the mean time he did get some notable students, such as Henri Duparc. After a while, a sort of "Franck school" of students arose, albeit against his will, who affectionately called him ‘Pater seraphicus’. It was not until he was 50 before he started to receive some acclaim as a composer, and from his 52nd he started a very prolific period, lasting until his death at the age of 68.
Nowadays, Franck is mostly known for his instrumental music, peaking at the famous Violin Sonata in A. Besides this work,, his small collection of organ works was particularly influential.
