G. F. Steinmeyer & Co., founded in 1847 by Georg Friedrich Steinmeyer, was a prominent German manufacturer of harmoniums and organs until 2001. The company, originally based in Oettingen, gained recognition for its significant contributions to organ building, including the world's largest church organ in Passau Cathedral and notable restorations like those in Ottobeuren Basilica. Over its history, leadership passed through several generations of the Steinmeyer family, with each contributing to the production of numerous organs and adapting to technological advancements. The company ceased active organ building in 2001 and was converted into a property management entity to preserve its historical assets. The legacy continues through Orgelbau Steinmeyer GmbH, founded by Karl Göckel.
