Pianoforte

The Stein family was a dynasty of keyboard makers originally from Augsburg and later Vienna. The first maker of the family was Johann Andreas Stein (1728–1792) who was credited with developing a new action, the prellmechanik, or the so-called "Viennese" action. Stein had several children that also built pianos, including his daughter Nannette and son Mattäus Stein. The brother and sister headed the Stein shop as their father's health failed, and after his death continued in this partnership. Nannette married Johann Andreas Streicher in 1794 and that same year the Stein shop was moved to Vienna. Nannette and Mattäus continued to build pianos together until 1802 when she and her husband started their own workshop using the Streicher name.
