Robert Jean Julien Planquette (* March 31, 1848 in Paris; † January 28, 1903 in Paris) was a French composer of popular music, especially operettas.
Little is known about his childhood and youth. July 31, 1850, for example is occasionally cited in addition to the date of birth given above. After attending the Paris Conservatory, he earned his living by composing piano reductions of operettas that were popular at the time. He composed on the side. After the war of 1870/1871 he began to compose small one act operettas which were performed in concert cafés. Spurred on by the success that followed, he created nearly 20 full-length works. Among his best-known operettas, in addition to ''Rip-Rip'', are ''The Bells of Corneville'', first performed in 1877 and the song ''Le régiment de Sambre et Meuse'' which was later arranged into a military march by Joseph Rauski. His contemporaries described Planquette's works which are rarely performed today, as delicate, graceful, cheerful, and of good craftsmanship.
