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.

Jakob Ludwig Felix Mendelssohn Bartholdy born and widely known as Felix Mendelssohn, was a German composer, pianist, organist and conductor of the early Romantic period.

Mendelssohn is often compared to Mozart. Both of them were child prodigies, both had a talented sister and they both died at a young age. Mendelssohn, who as a child also painted wrote poetry, was born in small family which converted to christianity from judaism. As a composer he preferred looking back, rather than forward: his main examples were Bach, Handel and Mozart. It was Mendelssohn who retrieved Bach from oblivion and pushed for a revival of his music, which still lasts today. One century after its premier, Mendelsson performed the St Matthew Passion for the second time ever, in 1829.

Three years, earlier, on his 17th, he had already composed his masterfully overture A midsummer night's dream op. 21, based on Shakespeare's play. Today, it is still considered as one of the absolute masterpieces in all of the orchestra reperoire. His Violin Concerto op. 64 belongs to the most beautiful works of the 19th century as well. During his travels through Europe, he wrote his brilliant Italian Symphony, Scottish Symphony and the overture The Hebrides.

Although Mendelssohn had a prosperous career, his weak physique made him emotionally vulnerable. The death of his favourite sister Fanny became fatal: Mendelssohn died in the same year, at the age of 38.

Sir William Walton, in full Sir William Turner Walton, (born March 29, 1902, Oldham, Lancashire, Eng.—died March 8, 1983, Ischia, Italy), English composer especially known for his orchestral music. His early work made him one of England’s most important composers between the time of Vaughan Williams and that of Benjamin Britten.

Walton, the son of a choirmaster father and a vocalist mother, studied violin and piano desultorily as a boy and also sang, with somewhat better results, in his father’s choir. He taught himself composition, although he received advice from both Ernest Ansermet and Ferruccio Busoni. In 1912 he entered the University of Oxford, where he sang in the choir of Christ Church. He put in the requisite four years of study but failed by one examination (Responsonions) to win a bachelor of music degree. At Oxford he had met the Sitwell brothers, Osbert and Sacheverell, by whom he was virtually adopted, and he spent most of the next decade traveling with them or living with them at Chelsea. During this period he composed Façade (1923)—a set of pieces for chamber ensemble, to accompany the Sitwells’ sister Edith in a recitation of her poetry—as well as Sinfonia Concertante for piano and orchestra (1928; revised 1943) and Portsmouth Point (1926), which established his reputation as an orchestral composer.

Walton was influenced by some of his older contemporaries, notably Edward Elgar, Igor Stravinsky, and Paul Hindemith. Hindemith was soloist in the first performance of one of Walton’s finest works, his Viola Concerto (1929). Walton also composed a number of scores for motion pictures, including Major Barbara (1941), Henry V (1944), Hamlet (1947), and Richard III (1954). His vocal music includes the oratorio Belshazzar’s Feast (1931) and the operas Troilus and Cressida (1954) and The Bear (one act; 1967). The composer received a knighthood in 1951.
