Welte-Mignon

Welte-Mignon is a physics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Welte-Mignon rather than just read about it. In short: M. Welte & Sons, Freiburg and New York was a manufacturer of orchestrions, organs and reproducing pianos, established in Vöhrenbach by Michael Welte (1807–1880) in 1832.

Key takeaways

  • Welte-Mignon belongs to physics; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Welte-Mignon to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Welte-Mignon from memory before moving on to harder problems.

Reference excerpt

M. Welte & Sons, Freiburg and New York was a manufacturer of orchestrions, organs and reproducing pianos, established in Vöhrenbach by Michael Welte (1807–1880) in 1832.

Overview

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 (U.S. patent 287,599), 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

From 1911 on, a similar system for organs branded "Welte Philharmonic-Organ" was produced. Thirteen well-known European organist-composers of the era, among them Alfred Hollins, Eugene Gigout and Max Reger were photographed recording for the organ, distinguished organists like Edwin Lemare, Clarence Eddy and Joseph Bonnet were recorded too. The largest Philharmonic Organ ever built is at the Salomons Estate of the Markerstudy Group. This instrument was built in 1914 for Sir David Lionel Salomons to play not only rolls for the organ but also for his Welte Orchestrion No. 10 from about 1900, which he traded in for the organ. One of these organs can also be seen in the Scotty's Castle museum in Death Valley where it is played regularly during museum tours. An organ built for HMHS Britannic never made its way to Belfast due to the outbreak of the First World War. It can currently be heard playing in the Swiss National Museum in Seewen.

Welte Inc. In 1912 a new company was founded, the "M. Welte & Sons. Inc." in New York, and a new factory was built in Poughkeepsie, New York. Shareholders were predominantly family members in the U.S. and Germany, among them Barney Dreyfuss, Edwin's brother-in-law.

As a result of the Alien Property Custodian enactment during the First World War, the company lost their American branch and all of their U.S. patents. This caused the company great economic hardship. Later the Great Depression and the mass production of new technologies like the radio and the electric record player in the 1920s virtually brought about the demise of the firm and its expensive instruments. Other companies with similar products like American Piano Company (Ampico) and Duo-Art also began to fade from the scene at this time, a list would go into the hundred.

From 1919 on, Welte also built theatre organs, in particular for installation in cinemas. With the introduction of "talkies" around 1927, the demand for these also began to diminish, and by 1931 production of such instruments had been severely curtailed. The last big theatre organ was a custom-built instrument for the Norddeutscher Rundfunk (NORAG) broadcasting company in Hamburg, still in place and still playing today. A number of other Welte theatre organs survive in museums. In 1932 the firm, now with Karl Bockisch as sole owner, barely escaped bankruptcy, and began to concentrate on the production of church and other speciality organs. The last project of Edwin Welte was an electronic organ equipped with photo-cells, the Lichttonorgel or Phototone-Organ. This instrument was the first ever to use analogue sampled sound. In 1936, a prototype of this type of organ was demonstrated at a concert in the Berliner Philharmonie. The production of these organs - in cooperation with the Telefunken Company – was halted by the Nazi-government because the inventor, Edwin Welte, was married to Betty Dreyfuss, who was Jewish. The business complex in Freiburg was bombed and completely destroyed in November 1944 by Operation Tigerfish . This event seemed to obliterate the closely kept secrets of the firm and their recording apparatus and recording process appeared lost forever. But in recent years parts of the recording apparatus for the Welte Philharmonic-Organs and documents were found in the United States. It was then possible to theoretically reconstruct the recording process. The Augustiner Museum of Freiburg keeps the legacy of the company – all that survived the Second World War.

Worked examples

Example 1 — a first encounter with Welte-Mignon

Start with the simplest possible case. Write down what Welte-Mignon claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Welte-Mignon before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Welte-Mignon ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Welte-Mignon

In research
Welte-Mignon appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Welte-Mignon in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Welte-Mignon is common in secondary-school and first-year university syllabi. It links to neighbouring topics Companies based in Baden-Württemberg, Defunct companies of Germany, Mechanical musical instruments, so understanding it makes those chapters shorter.
In everyday life
Look for Welte-Mignon outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
