Franz Peter Schubert (31 January 1797 – 19 November 1828) was an Austrian composer of the late Classical and early Romantic eras. Despite his short life, Schubert left behind a vast oeuvre, including more than 600 secular vocal works (mainly lieder), seven complete symphonies, sacred music, operas, incidental music, and a large body of piano and chamber music. His major works include the art songs "Erlkönig", "Gretchen am Spinnrade", "Ave Maria"; the Trout Quintet, the unfinished Symphony No. 8 in B minor, the "Great" Symphony No. 9 in C major, the String Quartet No. 14 Death and the Maiden, a String Quintet, the two sets of Impromptus for solo piano, the three last piano sonatas, the Fantasia in F minor for piano four hands, the opera Fierrabras, the incidental music to the play Rosamunde, and the song cycles Die schöne Müllerin, Winterreise and Schwanengesang.

Born in the Himmelpfortgrund suburb of Vienna, Schubert showed uncommon gifts for music from an early age. His father gave him his first violin lessons and his elder brother gave him piano lessons, but Schubert soon exceeded their abilities. In 1808, at the age of eleven, he became a pupil at the Stadtkonvikt school, where he became acquainted with the orchestral music of Joseph Haydn, Wolfgang Amadeus Mozart, and Ludwig van Beethoven. He left the Stadtkonvikt at the end of 1813 and returned home to live with his father, where he began studying to become a schoolteacher. Despite this, he continued his studies in composition with Antonio Salieri and still composed prolifically. In 1821, Schubert was admitted to the Gesellschaft der Musikfreunde as a performing member, which helped establish his name among the Viennese citizenry. He gave a concert of his works to critical acclaim in March 1828, the only time he did so in his career. He died eight months later at the age of 31, the cause officially attributed to typhoid fever, but believed by some historians to be syphilis.

Appreciation of Schubert's music while he was alive was limited to a relatively small circle of admirers in Vienna, but interest in his work increased greatly in the decades following his death. Felix Mendelssohn, Robert Schumann, Franz Liszt, Johannes Brahms and other 19th-century composers discovered and championed his works. Today, Schubert is ranked among the greatest composers in the history of Western classical music and his work continues to be admired and widely performed.
