Joseph Joubert

John Pierre Herman Joubert was a British composer of South African birth, particularly of choral works. He lived in Moseley, a suburb of Birmingham, England, for over 50 years. A music academic in the universities of Hull and Birmingham for 36 years, Joubert took early retirement in 1986 to concentrate on composing and remained active into his eighties. Though perhaps best known for his choral music, particularly the carols Torches and There is No Rose of Such Virtue and the anthem O Lorde, the Maker of Al Thing, Joubert composed over 160 works including three symphonies, four concertos and seven operas.

Joubert, an organist at Nantes Cathedral in the latter half of the eighteenth century, presented an oratorio of his own composition, La Ruine de Jérusalem, ou le Triomphe du christianisme, at a spiritual concert in 1776. According to Biographie universelle des musiciens et bibliographie générale de la musique (1883), he also composed the comic opera La Force de l’habitude for the Nantes theater in 1778, and was still living in Nantes in 1793.
