History

Rieger–Kloss traces its roots to 1873, when the Rieger brothers established an organ-building enterprise. The company associates its early development with the wider Rieger tradition, which continued separately after the political and social upheavals surrounding the end of the Second World War. Following the war, Czechoslovak authorities expelled the ethnic German owners and workers of the original business and nationalized the Rieger company. In 1948, the nationalized operation was combined with the workshop of Josef Kloss, which had also been nationalized. This merger created the Rieger–Kloss company in its postwar form. Former members of the original Rieger enterprise established a new Austrian company called Rieger Orgelbau, making the postwar Czech business distinct from that successor organization. The new company developed a substantial international profile during the socialist period. Its participation in the 1958 World Exhibition brought attention to its work and was followed by 46 commissions in Soviet republics. Rieger–Kloss built instruments for major public and religious institutions, including the Slovak Philharmonic Society in Bratislava, the Belarusian State Philharmonic in Minsk, Prague's Congress Hall, St. Egyd in Klagenfurt, Xinghai Concert Hall in Guangzhou, Trinity Lutheran Church in Roselle, Illinois, and the Concert Hall of the New Conservatory in Ostrava. These commissions illustrate the company's reach across Central and Eastern Europe, China, and the United States. Technically, the company worked in several major organ-building traditions. Its output included pneumatic, electro-pneumatic, and tracker-action mechanisms. The product range extended from portative and compact instruments to large concert and cathedral organs. Rieger–Kloss also undertook restorations of historic instruments, an important part of the specialist organ-building market. Reference material attributes more than 600 completed organs to the company, although it does not provide a complete production register. The company became privately owned in 1994. In July 1997, floods severely damaged its Krnov facilities and other property. Production was interrupted for roughly four weeks while the business dealt with the consequences. Despite the disruption, the company remained associated with international work and is described as active in the Americas and Asia during its later operating period. The name was also connected with guitar production, and a separate company bearing the same name was described as producing pianos; the available material does not clarify the corporate relationship between those activities and the organ manufacturer. Education formed another part of the company's identity. Rieger–Kloss established a school of organ building in 1992. The school accepted twelve students from different parts of Europe each year for a four-year course combining theoretical instruction, technical training, and practical workshop work. The curriculum included languages, mathematics, organ playing, organ history, physics, mechanics, pipe and action construction, acoustics, electrical engineering, materials, technical drawing, and economics. Students were required to build a complete organ independently before graduation and to pass demanding written and practical examinations. Entrepreneur Jakub Škrbel took over the company in 2011. The business was reported to have gone bankrupt in 2018. The available reference material does not document the legal outcome of the bankruptcy, a successor entity, or whether the Rieger–Kloss brand continued commercial production. Accordingly, the historical record supports describing the company as a major Czech organ-building name with an uncertain present status.
