(orig. Baldassare da Belgiojoso; b Paris, early 16th century; d Paris, c.1587)
Italian-French violinist, composer, and choreographer. He was a personal servant to Catherine de Médicis and musical tutor to her sons. He took part in the masquerade Défense du paradis (1572), arranged the Ballet aux ambassadeurs polonais (1573), and choreographed the Ballet comique de la reine in 1581. The latter, a five-hour extravaganza celebrating the marriage of the Duc de Joyeuse to the Queen's sister, is widely considered to be the first ballet de cour. As such, he is regarded as the first French choreographer.
