Jean-Guillaume de Neubourg-Wittelsbach
His compositions included music for a Dutch Singspiel, "Bacchus, Ceres en Venus", which can claim to be the first opera in Dutch, and from which songs were published in 1687, as well as works for the viola da gamba. Around 1696 he accepted an appointment to the court of Johann Wilhelm, Elector Palatine in Düsseldorf. After Johann Wilhelm's death in 1716, the electoral court moved to Mannheim.
