Robert Cambert was a French composer principally of opera. His opera Pomone was the first actual opera in French.
In 1669 Perrin founded the Académie Royale de Musique, under the auspices of the French King. Cambert was invited to join Perrin in the administration of the project which is considered today to be one of the founding influences of grand opera. However, both Perrin and Cambert were eventually replaced at the academy by Lully. Cambert, furious at the insult, and at the lack of interest in his work shown by the French monarchy, left France in 1673 to pursue his career in England.
