Hoffmann und Schindler, an organ building firm in Ostheim vor der Rhön, traces its lineage back to the Markert family of organ builders. Otto Hoffmann took over the business after the death of the last Markert family member, Otto Reinhold Markert, in 1944. Together with his brother Louis, they continued the tradition of organ building, eventually transitioning to mechanical slider chests in the 1960s. Despite the challenges posed by the Iron Curtain, the company expanded its reach, undertaking numerous new organ constructions and restorations until Louis's death in 1965. Under Otto's leadership, notable projects included the restoration of historical organs like the Herbst organ in Lahm/Itzgrund and the Schlimbach organs in various locations.

In 1985, Otto's sons, Horst and Günter Hoffmann, assumed control of the business. They oversaw a new wave of constructions and restorations, including significant projects like the reconstruction of the organ built by Johann Friedrich Wender in 1703 for the Bach Church in Arnstadt. Horst Hoffmann also played a pivotal role in founding the Ostheimer Organ Building Museum in 1993. Christoph Schindler, a longtime employee, became co-owner of the firm alongside Günter Hoffmann in 2010. With Günter's retirement in 2020, the company transitioned to the leadership of Christoph and his son Dominik, marking the continuation of the rich tradition of organ building into the seventh generation.
