Pleyel et Cie. ("Pleyel and Company") was a French piano manufacturing firm founded by the composer Ignace Pleyel in 1807. In 1815, Pleyel's son Camille joined him as a business partner. The firm provided pianos to Frédéric Chopin, who considered Pleyel pianos to be "non plus ultra". Pleyel et Cie. also operated a concert hall, the Salle Pleyel, where Chopin performed his first – and last – Paris concerts. Pleyel's major contribution to piano development was the first use of a metal frame in a piano. Pleyel pianos were the choice of composers such as Chopin, Debussy, Saint-Saëns, Ravel, de Falla and Stravinsky and of pianists and teachers Alfred Cortot, Philip Manuel and Gavin Williamson. Nineteenth-century musicians involved in the company's management included Joseph O'Kelly and Georges
