The Welte Light-Tone was one of the last instruments designed by Edwin Welte (1876-1958) of the famous Welte-Mignon mechanical instrument manufacturers. Welte had become fascinated with the possibility of using optical disks since 1925 and produced a number of prototypes using clay optical disks before completing the production version of the Lichttonorgel. The organ premiered in 1936 at the Berlin philharmonic but any potential the instrument had was destroyed by the Nazi’s disapproval of Welte due to his marriage to a German Jew. After the war Welte continued to try and make a commercial success of the instrument but eventually foundered due to the complexity of the photo-electric system and from increasing competition from cheaper and more efficient instruments such as the Hammond Organ. Welte never built a production model of the Lichtonorgel.
The instruments sound generation unit consisted of 12 glass disks which were printed with 18 different looped waveforms in concentric rings. The glass ‘tone wheel’ disks were rotated over a series of photoelectric cells, filtering a light beam that controlled the sound timbre and pitch. The resulting combinations of tones gave 3 different timbres for all the octave registers of each note on the keyboard.
The German arm of the Welte-Mignon company in Frieburg was completely destroyed in 1944 by allied bombing and all of the companies closely kept secret designs were lost forever.
Edwin Welte (1876-1958) and his brother-in-law, Karl Bockish, developed the Welte-Mignon reproducing piano in 1904 for M. Welte & Soehne of Freiburg, Germany. Music roll recording commenced in 1905. The recording piano and the reproducing system were entirely new inventions which astounded the musicians and fans in Europe. In 1906 (?) he established “The Welte Artistic Player Piano Company” in a showroom in New York and soon was producing pianos and music rolls for American customers.
The Welte Company
The Welte Company was a German organ firm which was first established in 1832 at Vörenbach (Black-Forest) by automata manufacturer Michael Welte (1807-1880). In c1865 he moved to Freiburg/Breisgau and the firm was registered there as M. Welte & Söhne. During the remainder of the 19th century the Welte firm expanded considerably and became particularly noted for their orchestrions. Welte’s “Cabinet player”, a reproducing piano without keyboard which bore the Mignon label, was first patented in 1904 while the firm was under the direction of Edwin Welte (1876-1958, grandson of the founder). The prototype was exhibited during late 1904 in Leipzig and became commercially available from early 1905. The Vorsetzer came on the market in 1908. Mignon was integrated into their upright pianos in 1909, and into their grand pianos from 1913. In 1908 the technology was adapted and applied to the Welte “Philharmonic Autograph Organ”. This was the forerunner of the “Welte-Philharmonie Organ” which was first publicly displayed at the Turin Exhibition of 1911. The firm then went on to successfully market player organs, cinema organs and, later, when their market contracted during the 1930s, church organs. They concurrently produced rolls of performances by the greatest organists of the day and sold them with considerable commercial success. From 1865-1917 they also ran a branch in New York (M. Welte & Sons) under Emil Welte (1841-1923, eldest son of the founder), but it was closed during World War I as an “alien enterprise”. Welte’s instruments became status symbols and the epitome of entertainment in their day. They were installed in stately houses, palaces, schools, department stores (Harrods in London had one), yachts, ships (one was manufactured just too late to be aboard the Titanic) and even apparently a “house of pleasure” (the Atlantic Garden orchestrion). Around the world they were dispersed throughout Europe, USA, with their market is known to have extended much further – to Istanbul, Russia, China and Sumatra for example. The top of Welte’s Orchestrion/player-organ range was the “Welte-Philharmonie”. Very few of the full- sized model were ever manufactured. From about 1926 Welte began to be threatened by a rapidly growing radio and recording industry. Business declined so much that, in 1932 they narrowly escaped bankruptcy. At about this time they were also involved in a collaboration with the Telefunken Company which was terminated because Edwin Welte’s first wife, Betty Dreyfuss, was Jewish. This stalled collaboration involved the development of electronic organs. Using (analog) sampling and photo-cells, truly prophetic developments at that time, had Welte been successful they might well have eliminated the Hammond organ from the pages of history. It was World War II which finally precipitated the total demise of the firm. The Freiburg premises – all stock, instruments and historical documents – were effectively annihilated by British bombing in November 1944. The bombed out factory was something of a landmark by the Freiburg railway station for at least decade until the mid-1950s. (from: Museum of Music Automatons Seewen)
