Overview
Reiser Orgelbau was a German organ-building company based in Biberach an der Riß. Its origins go back to 1906, when Albert Reiser (1874–1947) acquired the Schefold workshop and continued it under his own name. Reiser had learned the organ-building trade in the workshops of Mönch in Überlingen, Gebr. Späth Orgelbau, and Schlimbach in Würzburg. By the 1930s the firm was counted among the representative organ workshops of southwestern Germany. After Albert Reiser's death, his sons Johann (Hans), Albert, and Josef took over the business in 1948 and traded as Gebr. Reiser. In 1983 Hans Peter Reiser (born 1943), son of Johann Reiser, took over the workshop under the name Reiser Orgelbau. The company built around 500 organs. Its motto was: “Das Bild einer Orgel entsteht im Kopf. Reiser baut Orgeln mit besonderer Klangfülle. Jeder Raum wird so neu erlebbar.” (“The image of an organ is formed in the mind. Reiser builds organs with a special fullness of sound. Every space becomes newly experienceable.”) The firm is considered defunct. Tuning and maintenance contracts are handled by Josef Pferdt Orgelbau in Isny im Allgäu. The company's instruments are documented in organ inventories and literature, including Wolfgang Manecke and Johannes Mayr's Historische Orgeln in Oberschwaben: Der Landkreis Biberach (1995) and Wolfgang Manecke's article “100 Jahre Orgelbau Reiser” in Ars Organi (2006).
