Sauter Pianofortemanufaktur GmbH & Co KG is a German piano manufacturer in Spaichingen, Baden-Württemberg.
Sauter was founded by Johann Grimm in 1819. In 1813 Grimm traveled to Vienna to study piano building with Johann Andreas Streicher and his wife, Nanette Streicher, the noted pianoforte builder. Ludwig van Beethoven is known to have purchased instruments from Nanette Streicher, and she ran the composer's household for many years. Upon completing his apprenticeship with Nanette Streicher, Grimm returned to his hometown of Spaichingen in 1819 and began building virginals.[1][2] Grimm's successor was his nephew Carl Sauter, who built the workshop into a factory employing a dozen apprentices in 1846, becoming a prominent instrument manufacturer in the region of Swabia. After Carl's early death, his son Johann Sauter took over operation of the company together with his mother. Johann traveled extensively, including to America, researching contemporary instrument construction in advance of the company's transition from manufacturing virginals to building the larger, more complex and expensive pianoforte, the predecessor to the modern piano. Johann Sauter's son, Carl Sauter II, led the company beginning in 1909, and initiated an expansion of the factory in Spaichingen to increase production.
In 1948 Carl Sauter's son, Hans Sauter, took over company operations, and under his leadership the business began worldwide export of its instruments. The final Sauter family member to head the company, Carl Sauter III, brother of Hans Sauter, took over the company in 1968 and constructed a new factory building between 1974 and 1983. After Carl Sauter III's retirement in 1993, Otto Hott acquired a majority share of the company with Ulrich Sauter, of the original Sauter family, remaining in the company as an authorized officer and director of operations.
