How Old is my Gaveau Piano?

Founded in Paris in 1847 by Joseph Gabriel Gaveau, this French firm was to gain an excellent reputation for high-quality harpsichords, and in particular small upright pianos.

By 1907, when Gaveau was passed to the founder’s son, Etienne, the firm was producing and selling over 1,000 pianos a year. Etienne Gaveau expanded the factory and had a 1,100-seat concert hall, Salle Gaveau, built in Rue la Boetie in Paris.

Between the 1910s and 1940s, the severe economic climate meant that Gaveau, now joined by his sons Marcel and Andre, had to diversify to compete with their main competitor, Pleyel. Production started of small unfretted clavichords and spinets, made possible by the short-term hiring of Arnold Dolmetsch, who designed these instruments for Gaveau between 1911 and 1914. On Dolmetsch’s return to England, Gaveau returned to producing uprights pianos only.

In 1960 Gaveau joined forces with Erard and a year later with their great rival Pleyel.

How Old is my Irmler Piano?

 Irmler had achieved a good profitable export business, particularly to North America, and they also had a steady home market. However, as other German makers were invading their home territories, Irmler quickly had to develop more aggressive tactics in selling their pianos and keep apace with the most advanced ideas of the time. In 1861 they introduced stream-driven works in their factory. Later that same year Otto died, leaving the running of the factory to his younger brother, Oswald. The success that followed marked Irmler as one of Germany’s finest makers of pianos and by the turn of  the century they had been honored by the courts of the emperor of Austria and the kings of Wurttemberg, Sweden, and Romania.

Oswald died in 1905, leaving the firm in the very capable hands of his sons, Emil and Otto. Irmler carried on producing pianos independently until the 1950s. Today they are made in Asia and European factories under the name Irmler Europe and imported into the United States by German Piano Imports.

How Old is my Samik Piano?

Founded in 1958 by chairman Hyo Ick Lee, the company swung into full production of upright pianos under the brand name Horugel. This name would be used until the 1970s, when the Samik brand was introduced. A leading light in its domestic market, Samik became, in 1964, the first Korean company to export pianos, sending ten uprights to Hongkong. Output of uprights steadily grew and, spurred on by the Price of Piano Development awarded by the Korean Ministry of Trade and Industry in 1970, Samik became the first Korean manufacturer of grand pianos.

         The following years were to be spent securing a position on the world stage, and resources were focused on expanding the company’s exports. Samik opened a branch in West Germany in 1980 and later entered a joint venture with the American Baldwin Piano and Organ Company.

The company has worked tirelessly since its founding to expand its production facilities. By the 1990s, after several changes in factories, the company could boast separate plants for upright, grand and digital piano production, all incorporating the latest development in machinery. In 1996 Samik opened a factory in Indonesia incorporating its own wood processing plan, were both uprights and grands are now built. With a new line of pianos for the millennium-and after just forty-four years producing musical instrument-Samik have come a long way in a short time, and look set to play a significant role in the future.

How Old is my Sauter Piano?

The company’s reputation was firmly established by the time Carl Sauter III took charge in the 1960s. But he was dissatisfied with the notable differences in repetition speeds between the upright and grand actions, and he led the development of an improved action known as the R2, for the upright range. A new factory was opened in 1984, in which machines were installed to speed production, but the company insists that many parts are still made by hand in the traditional way.

Carl Sauter’s son, Ulrich, is now a prominent member of the firm, ensuring that the family tradition lives on into a new century, and 2001 has already seen the unveiling of a new Sauter concert grand after years of development.

Sauter developed the “2 Double Escapement Action” for upright pianos to even out the differences in touch between an upright piano action and that of a grand. The action includes an extra jack spring to aid repetition.

A grand piano was made by Sauter for the Paris Conservatory to help a pianist to perform music written for a prepared piano. It was decorated with inlaid lines on the dampers and colored lines on the soundboard to identify the keyboard layout on the strung back and also to indicate where to touch the strings to produce harmonics. This piano has now been integrated into the Sauter line.
