German piano action and parts manufacturer. The firm was founded by Louis Renner in Stuttgart in 1882. His son, Oscar, took over 20 years later in partnership with Wilhelm Megenhardt, with Renner managing the technical side and Megenhardt in charge of business and finances. Initially, much of the output was handcrafted, but production was rapidly mechanized for greater consistency and productivity, and Renner soon became known for high-quality action parts, including, by 1906, piano hammers. The firm moved to a new larger factory in 1902, at which time they had 35 employees, growing to more than 400 in the 1930s. The factory was nearly destroyed in 1944, but by 1948 it was again producing actions, initially for piano manufacturers in German-speaking parts of Europe, but soon internationally. An additional factory was opened in Odenheim by 1960 for storing and processing wood and for pre-assembly and hammer making.
