From 1832 until 1932, the firm produced
mechanical musical instruments of the highest quality. The firm's founder, Michael Welte (1807–1880), and his company were prominent in the technical development and construction of
orchestrions from 1850, until the early 20th century. In 1872, the firm moved from the remote
Black Forest town of
Vöhrenbach into a newly developed business complex beneath the main railway station in
Freiburg, Germany. They created an epoch-making development when they substituted the playing gear of their instruments from fragile wood pinned cylinders to perforated paper rolls. In 1883, Emil Welte (1841–1923), the eldest son of Michael, who had emigrated to the United States in 1865, patented the
paper roll method (), the model of the later
piano roll. In 1889, the technique was further perfected, and again protected through patents. Later, Welte built only instruments using the new technique, which was also licensed to other companies. With branches in New York and Moscow, and representatives throughout the world, Welte became very well known. The firm was already famous for its inventions in the field of the reproduction of music when Welte introduced the Welte-Mignon
reproducing piano in 1904. "It automatically replayed the tempo,
phrasing, dynamics and pedalling of a particular performance, and not just the notes of the music, as was the case with other player pianos of the time." In September, 1904, the Mignon was demonstrated in the
Leipzig Trade Fair. In March, 1905 it became better known when showcased "at the
showrooms of Hugo Popper, a manufacturer of roll-operated
orchestrions". By 1906, the Mignon was also exported to the United States, installed to pianos by the firms
Feurich and
Steinway & Sons. As a result of this invention by Edwin Welte (1876–1958) and his brother-in-law Karl Bockisch (1874–1952), one could now record and reproduce the music played by a pianist as true to life as was technologically possible at the time. Most of the renowned pianists of the time recorded for Welte-Mignon, a complete list would go into the hundred. A Steinway Welte-Mignon reproducing piano and several other player pianos and reproducing pianos can be seen and heard at the
Musical Museum, Brentford, England. ==Welte Philharmonic Organ==
