In 1934 Pleyel acquired the firm of  Antoine Bord. In 1961, facing financial difficulties, the firm merged with the combined firms of Erard and Gaveau. This conglomerate was acquired in 1971 by the Shimmel Company, which produce a small number of Pleyel pianos each year. Then in 1994, the Rameau company bought the names of Pleyel and Gaveau, and two years later Pleyel took control once more, opening a state-of-the-art production and R&D unit in Ales in the South of France, where they continue to make superb pianos faithful to the Pleyel tradition.
