Johann Adolph Ibach founded an organ and piano workshop in Wuppertal-Beyenburg in 1794, which evolved into the piano and grand piano factory Rud. Ibach Sohn in 1869. Today, the Ibach family company in Schwelm is the oldest producing piano manufacturer in the world. The historical photos in this illustrated book, spanning from the 19th century to the end of the 20th century, evoke the "inner workings" of the factory and the daily work life.
