Juan Andres was born at Planes in the province of Valencia, Spain and became professor of literature at Gandia and finally royal librarian at Naples. He died at Rome. He is the author of many miscellaneous treatises on science, music, the art of teaching the deaf and dumb, and others. His chief work, the labour of fully twenty years, is entitled Dell'origine, progressi, e stato attuale d'ogni Letteratura (7 vols., Parma, 1782-1799). A Spanish translation by his brother Carlos appeared at Madrid between 1784 and 1806, and an abridgment in French (1838-1846) was compiled by the Jesuit Alexis Nerbonne. The original was frequently reprinted during the first half of the 19th century.
