François-Joseph Gossec (17 January 1734 – 16 February 1829) was a French composer of operas, string quartets, symphonies, and choral works.
The son of a small farmer, Gossec was born at the village of Vergnies, then a French exclave in the Austrian Netherlands, now in Belgium. Showing an early taste for music, he became a choir-boy in Antwerp. He went to Paris in 1751 and was taken on by the composer Jean-Philippe Rameau. He followed Rameau as the conductor of a private orchestra kept by the fermier général Le Riche de La Poupelinière, a wealthy amateur and patron of music. Gradually he became determined to do something to revive the study of instrumental music in France.
Gossec's own first symphony was performed in 1754, and as conductor to the Prince de Condé's orchestra he produced several operas and other compositions of his own. He imposed his influence on French music with remarkable success. His Requiem premiered in 1760, a ninety minute piece which made him famous overnight. Years later, in 1778, Mozart visited Gossec during a trip to Paris, and described him in a letter to his father as "a very good friend and a very dry man".
Gossec founded the Concert des Amateurs in 1770 and in 1773 he reorganised the Concert Spirituel together with Simon Leduc and Pierre Gaviniès. In this concert series he conducted his own symphonies as well as those by his contemporaries, particularly works by Joseph Haydn, whose music had become increasingly popular in Paris, finally even superseding Gossec's symphonic work.
In the 1780s Gossec's symphonic output decreased as he began concentrating on operas. He organized the École de Chant in 1784, together with Etienne Méhul, was conductor of the band of the Garde Nationale of the French Revolution, and was appointed (with Méhul and Luigi Cherubini) inspector of the Conservatoire de Musique at its creation in 1795. He was an original member of the Institut and a chevalier of the Legion of Honour. In 1815, after the defeat of Napoleon at Waterloo, the Conservatoire was closed for some time by Louis XVIII, and the eighty-one year-old Gossec had to retire. Until 1817 he worked on his last compositions, including a third Te Deum, and was supported by a pension granted by the Conservatoire. He died in the Parisian suburb of Passy. The funeral service was attended by former colleagues, including Cherubini, at Père Lachaise Cemetery in Paris. His grave is near those of Méhul and Grétry.
Some of his techniques anticipated the innovations of the Romantic era: he scored his Te Deum for 1200 singers and 300 wind instruments, and several oratorios require the physical separation of multiple choirs, including invisible ones behind the stage. He wrote several works in honor of the French revolution, including Le Triomphe de la République, and L'Offrande à la Liberté.
While most people would have difficulty recognizing Gossec's Gavotte by its title, the melody itself remains familiar in the United States and elsewhere because Carl Stalling used an arrangement of it in several Warner Brothers cartoons.
He was little known outside France, and his own numerous compositions, sacred and secular, were overshadowed by those of more famous composers; but he was an inspiration to many, and powerfully stimulated the revival of instrumental music.
