Eberhard Friedrich Walcker

Rejection by Wilhelm Strebel because of Walcker's 100th anniversary, letter dated August 20, 1920

Eberhard Friedrich Walcker (born July 3, 1794 in Cannstatt ; † October 2, 1872 in Ludwigsburg ) was a German organ builder and, like his grandson Oskar Walcker (1869–1948, company owner since 1916), “Walcker Hof organ builder under King Wilhelm II. from Württemberg and suppliers to the Vatican ”. The organ building company in Ludwigsburg, which went back to him, was at times one of the largest and most renowned in the world.

description

Eberhard Friedrich was born as the son of the organ builder Johann Eberhard Walcker , who founded his workshop in Cannstatt in 1780. In 1820 he transferred the company to Ludwigsburg, the company's long-term headquarters. Eberhard Friedrich Walcker is considered the most important German organ builder of the 19th century. It gained importance through various technical and sonic improvements, in particular through the perfecting of the cone chest . He was trained in the organ building workshop of his father Johann Eberhard Walcker and founded his own workshop in Ludwigsburg in 1821 (from 1854 under the name EF Walcker & Cie. ). His first important work was the organ in the Paulskirche in Frankfurt, completed in 1833 (Opus 9), which received international attention.

Walcker's epoch-making innovations in organ building include the perfecting and dissemination of the cone chest, a style-defining disposition for German organ romanticism and the consistent use of partials inspired by Abbé Vogler . Walcker succeeded in building the first open 32 'register, which, due to its design, turned out to be satisfactory in terms of sound including the low notes. It is also thanks to him that the blind sill was introduced in Germany; a facility that he - mediated by Vogler - took over from England and France .

student

Carl Gottlieb Weigle began an apprenticeship as an organ builder with his brother-in-law Eberhard Friedrich Walcker in 1826. Later he became the first assistant in almost all of the company's large organ buildings, especially the renovation of the Stuttgart collegiate church organ from 1837 to 1845. In 1845 he set up his own workshop in Stuttgart, which was continued as the Friedrich Weigle Organ Builder .

In 1864, the previously employed by Walcker organ builder founded Johann Nepomuk Kuhn with another employee in Männedorf on Lake Zurich , the company Kuhn Organ Builders .

development

The company stayed in Ludwigsburg until 1974. In 1957 a branch was founded in Vienna , which then moved to Guntramsdorf in 1961 . After a stopover in Murrhardt , the main company moved to Bliesransbach (district of Kleinblittersdorf ) in Saarland . After an insolvency in 1999, both companies were managed independently from the year 2000 by Werner Walcker-Mayer's sons as organ builder Michael Walcker-Mayer in Guntramsdorf and as organ builder Gerhard Walcker-Mayer in Bliesransbach. Both companies continue to manufacture Walcker organs and see themselves as part of the Walcker organ building tradition.
