Friedrich Ladegast

Friedrich Ladegast (born August 30, 1818 in Hochhermsdorf , † June 30, 1905 in Weißenfels ) was an important German organ builder in the second half of the 19th century .



Friedrich Ladegast was born on August 30, 1818 as the eighth child of the house owner, carpenter and pipe master Johann Christlieb Ladegast and his wife Eva Rosina, nee. Dathin, born in Hochhermsdorf (today Hermsdorf) near the town of Geringswalde in Saxony . The Ladegasts were not a traditional family of musicians, but the children came into contact with music by making music in the family circle. Instructions in piano playing , which were later supplemented by lessons on the organ , initiated the young Friedrich in the basics of this art. The love for music and the craftsmanship acquired from his father went together. In his later years he said to his friend, the organist William Hepworth from Chemnitz : "Basically, I am just as musically inclined as you are, only that time and circumstances do not allow me to develop my skills in this regard." moved to become an organ builder can only be assumed today. In addition to the fact that his older brother Christlieb also chose this profession, the role model of the famous compatriot Gottfried Silbermann , who worked 150 years earlier in Freiberg , about 50 km away , will have had a strong, if not necessarily direct, influence on the brothers . There is no doubt that the Ladegasts had known his plants in Rochlitz , Ringethal and Schweikershain, which are located in the immediate vicinity of their home village, since childhood .


Friedrich received his first training as an organ builder in his brother's workshop in Geringswald. His journeyman piece is in the Ev.-luth. Church to Tanneberg near Mittweida . In the following years of his wandering he worked in various organ workshops in Central Germany ( Kreutzbach in Borna , Mende in Leipzig and Zuberbier in Dessau ). Later study trips led him a. a. also to Alsace , southern Germany and France . According to his own information, Ladegast studied the early works of Gottfried Silbermann in Strasbourg in Alsace , but not, as was mistakenly assumed in the past, as an employee of Martin Wetzel's workshop directly after his apprenticeship in the organ building workshops in Central Germany.

Even the assumption that Friedrich Ladegast got to know the famous French organ builder Aristide Cavaillé-Coll personally on one of his trips and even worked for him for some time, proves to be incorrect based on current knowledge. Both organ builders, however, held each other in high esteem. For example, before the construction of the large organ for the Nikolaikirche in Leipzig (1862) , Friedrich Ladegast found out about the technical systems in the large organs of Cavaillé-Colls on a study trip. Albert Schweitzer writes:

“The great French organ builder Aristide Cavaillé-Coll made it [F. Ladegast] is valued as the best among contemporary organ builders of the second half of the 19th century. I still knew Cavaillé-Coll and can confirm that he spoke of Ladegast with admiration. "


In 1846, Friedrich Ladegast applied for a branch as an organ builder and instrument maker in the Saalestadt Weißenfels , which was approved in early 1847. His newspaper advertisement, which appeared shortly afterwards in the Weißenfelser Kreisblatt, shows the following: “I admit that I have settled here as an organ builder and instrument maker. I ask for your trust, which I will always make myself worthy of the strictest realism. Weißenfels, February 5, 1847 ”.

Not only the protection of the Weißenfels royal music director Ernst J. Hentschel , but also economic factors, played a decisive role in the decision to settle in Weißenfels of all places . Weißenfels, not far from the large cities of Leipzig and Halle , was one of those central German cities that developed rapidly in the course of industrialization . The opening of a railway line to Erfurt on June 6, 1846 brought considerable advantages to the location. The Saale River was also still navigable at that time.

As can be seen from his application for a settlement permit, Ladegast was already familiar with the area through his stay in Lützen to repair the Kreutzbach organ (1839) in the local church. There were no other organ building workshops in the area and therefore little competition. In addition, the city had a teacher training college, which had developed into a center for teacher training in the Prussian province. Since 1822 the institute has been under the direction of the famous pedagogue Wilhelm Harnisch . a. shaped by such personalities as Ernst J. Hentschel and Moritz Hill . Ladegast had a friendly relationship for years with Hentschel, who was also the godfather of his children.


Although the economic aspects were promising, the order situation remained poor in the first few years. In 1849, through the intercession of David Hermann Engel , Ladegast received an order for an organ in the St. George Church in Geusa near Merseburg , which should fundamentally change the future of the young organ builder. Ladegast put everything on one card - his skills, his own resources, his own visions - and won. The organ, originally planned as a one-manual work, was expanded to include a second manual beyond the contract - at Ladegast's own expense. When the organ was accepted, Engel was “delighted” by the sound, the choice of material, the quality of the workmanship - all those aspects that brought Ladegast fame during his lifetime and still distinguish his organs today. In 1855 Ladegast got another order for an organ in the St. Thomas Church in the Geusa district of Blösien .

New orders and the associated success were not long in coming. In 1850, Ladegast acquired a two-story house on Naumburger Strasse, where he set up his workshop and in which five new plants were built in the same year. With the exception of the organ in the village church in Albersroda (II / 15), these were single-manual works with 5 to 10 registers.

On November 3, 1850 at the age of 32, Friedrich Ladegast married the 24-year-old Johanne Rosette Bertha Lange (* May 7, 1826, † January 6, 1892), daughter of the Weißenfels city organist. The marriage was blessed with twelve children. However, seven of the children died prematurely. At the end of 1851, Ladegast received an order to build a new organ for the St. Peter town church in the town of Hohenmölsen, 15 km away . With its 24 sounding stops, this organ is today his largest two-manual instrument, which - with the exception of the prospect pipes and the wind turbine - has been preserved in its original form. It occupies a special position in his work, not only because it was the first major commission, but because, due to its sound and structural soundness, it formed a basis for the major commissions that followed immediately afterwards in Merseburg, Schulpforta , Leipzig, etc.

When the Merseburg cathedral organ had to be repaired again in 1853, the cathedral organist Engel could not consider anyone else as a guest. A repair costing 4,500  thalers became a new building for 6,258 thalers. While retaining the case of the old organ and 26 of its stops, which were later also replaced by new ones, Ladegast set up a work with 81 stops on 4 manuals and pedal, about which it was already said during the construction that “this organ work is a new one Section in the art of organ building designates in that things have been achieved here that have not yet occurred on any other organ ”. The inauguration took place on September 26, 1855. This organ, which was the largest in Germany at that time, brought Ladegast a lot of recognition and fame and placed him on a higher level among the ranks of smaller organ builders. The work was admired by a number of well-known intellectuals and inspired, for example, Franz Liszt to some of his great organ works.

Before his next big order, the organ for the Leipzig Nikolaikirche (IV / 84), which was completed in 1862 as the largest organ in Saxony at the time, around 16 instruments were made, including the first three-manual organ for the Pforta State School (Schulpforta) near Naumburg (1857 , 34 registers). The work was demolished in the 1960s and stored in the attic until it was stripped of essential parts at some point. However, there is still a small Ladegast organ from 1884 with 11 registers in the auditorium of the state school. In 2005 this small organ was repaired by the organ building workshop Rösel & Hercher . Two organs went beyond the region to East Prussia ( Memel , 1858, II / 44) and Lower Silesia ( Görkau , 1859, II / 13).

In 1864, Ladegast built his second three-manual organ (41 stops) for the town church of St. Marien on behalf of the municipality of Weißenfels, which is today his oldest three-manual organ. Also in 1864, Ladegast's third three-manual organ - a work with 39 registers for the castle church in Wittenberg in the historic case by J. E. Hübner (1767) - was completed. In 1892 this got a new neo-Gothic case and was supplemented with a Barker machine .

New orders for large instruments required a larger workshop. In 1865, Ladegast applied for a permit to build a new workshop on Naumburger Strasse. Thus, a room was created that later even housed the organ for the Schwerin Cathedral . Such an assembly hall made it possible to relieve individual production sites such as the pipe-making and windchest workshops and allowed several instruments to be built at the same time. In addition, the possibility of installation made it possible to perform a pre-intonation of a new organ, to check the action of its suitability and to eliminate any defects in the workshop. Furthermore, this led to the crystallization of individual professional special areas with specially trained personnel such as tin workers, pipe or windchest makers and the like. Ä.

This practice only became generally accepted among central German organ builders in the 1880s and 1890s with the increase in production and exports. The organ building company Jehmlich , founded in 1808, did not get its large assembly hall until 1897. The also traditional Saxon organ building company Eule, founded in 1872, built its hall in 1888. Friedrich Ladegast can therefore be seen as a progressive-thinking organ builder of his time who did not completely shut himself off to industrialization , describe. Unfortunately, the workshop was completely demolished in 1979.

In the period between 1864 and 1871, around 25 new organs left the workshop, three of them went to the Baltic States , one to Moscow (op. 50, 1868) and two to the Palatinate. Other instruments were rebuilt or repaired.

The year 1871 was groundbreaking for Ladegast, which finally put him in the ranks of internationally important organ builders. This year his work was completed with 84 voices in Schwerin Cathedral. The construction cost 11,000 thalers, took three years and was completed on September 6, 1871. In this instrument, Ladegast used everything that had convinced him of the technical innovations and findings of that time. Besides the already proven Barker machine, the split into divisions slider chest and the radial angle and Wellentraktur he built for the first time in the history of German organ building in an organ, the pneumatically controlled crescendo one. With these innovations, which actually only became standard with the introduction of tube pneumatics, he stepped ahead of the times and thus set indelible marks in German organ building history.

On November 10, 1871, Ladegast received the Gold Cross of Merit awarded by the Duke of Mecklenburg-Schwerin - the House Order of the Wendish Crown - for organ building in Schwerin . The instrument, built in 1872 for the St. Jakobskirche in Köthen , is still the largest organ in Anhalt today .

In 1872 he was commissioned to build the organ for the Great Hall of the Vienna Musikverein . Its housing was designed by the architect Theophil von Hansen . The organ had 52 registers, distributed over three manuals and pedal, whereby he provided mechanical slide chests for the manual works and cone chests for the pedal work. Anton Bruckner took part in the opening concert on this organ. In 1907, however, this organ was replaced by a new instrument.


The general change from a craft business to a factory as the main feature of industrial development, triggered by the invention of the steam engine , brought about profound changes in organ building as well. The growth of cities associated with the industrial revolution called for new churches and organs. In addition, many instruments that were perceived as out of date were replaced. Traditional craft production could no longer fully satisfy this increased demand. The livelihood of many companies no longer only depended on the quality of their work, but increasingly on their ability to increase production volumes and keep prices low. Only larger companies were able to meet these enormous requirements.

Around 1840, the company EF Walcker & Cie. , Ludwigsburg, the first cone shop organ was built. This new wind chest system led to divisions and disputes like no other invention in organ building. Received enthusiastically by some, frowned upon by others, it traced the path of organ building at that time. No well-known organ workshop passed the cone chest. While some companies such as Walcker and Sauer made a complete changeover to this wind chest system, others returned to the sliding chest after a few attempts with the cone chest or used both systems at the same time. The latter also included the Ladegasts workshop. He himself comments on the use of both systems as follows: "In fact, I use all systems, sometimes different in one organ, each where it seems appropriate to me."

Indeed, in the seventies and eighties one can find both pure slider chest organs (e.g. in the parish church in Posen , III / 43, 1876) and pure cone chest organs (e.g. in the St. Nicholas Church in Spandau , III / 45, 1880) as well as organs with a mixed wind chest system (e.g. St. Andreas Church in Rudolstadt , III / 33, 1882). Both organs with slide chests in the manuals and cone chests in the pedal and vice versa were built. The latter combination is preferred by Ladegast in his later creative period. Nevertheless, he remained a staunch supporter of the slider chest all his life. On January 13, 1880, he addressed the then general secretary of the Vienna Society of Friends of Music , Leopold Alexander Zellner , the lines that had already become proverbial:

“[…] Of the works delivered in the past year, two were with a cone shop. In many respects, the same are easier to manufacture than slider chests (but to be honest!) The slider chests will not be displaced by the cones. However, since almost everything is crazy, it doesn't help, you have to cry with me! "

It was not until the late 1880s that the workshop turned more intensively to pneumatics. However, since by 1890 at the latest almost all well-known organ building companies started building the pipe pneumatics and already had their own sophisticated systems, the traditional workshop from Weißenfels fell by the wayside in the tough competition - the train had left. The once famous company was gradually pushed out of the market. The large orders were reserved for other companies that were now building the organs that were considered modern.

In 1884, when the new organ was awarded for the newly built Gewandhaus in Leipzig , the company suffered its first major defeat against the Walcker company. The Frankfurt organ building company Sauer contested further orders for him in the city of Leipzig, which previously belonged to "his territory". The large buildings for the Petrikirche (1886, III / 60) and the Thomaskirche (1889, III / 63) were awarded to Sauer. The answer to the question of whether this development is solely due to alleged intrigues, of which Ladegast often spoke, remains speculation.

Closely connected with the technical advancement in organ building was the change in the sound aesthetics of the organ to the late romantic orchestral style. Due to Ladegast's sound ideas, which at the beginning of the 1890s were considered too straightforward and outdated, his works were increasingly no longer competitive in this respect.

The number of organ builders who learned and worked at Ladegast is large. These include:

End of life

The Ladegast family grave at the Weißenfels cemetery

After the death of his wife in 1892, Friedrich Ladegast withdrew more and more from the public. Still involved in the management of the company until then, in 1898 he finally handed the scepter over to his son Oskar Ladegast (born September 26, 1858 - † January 4, 1944).

After a stroke, Friedrich Ladegast was lovingly cared for by his daughter Elisabeth. He died in her arms on June 30, 1905. His last words were, "Help me, help me!" Master's death was publicly noted with great respect. As early as August 3, 1905, the following message from the city council appeared in the Weißenfelser Tagesblatt: “The city council honored the old master of organ building, Friedrich Ladegast, who recently died, by taking the road connecting Beuditz and Gustav Adolfstraße Added the name 'Ladegaststrasse'. "

The importance of this outstanding master of German organ building can best be understood with the words of Albert Schweitzer to the then Merseburg cathedral organist Hans-Günther Wauer (in a letter from Lambarene from 1958):

“I consider Friedrich Ladegast to be the most important organ builder after Silbermann, whose tradition he continues. Both in terms of technology and sound, his creations are unique in a certain way. I myself was moved by the variety and the beauty of the tone of the Ladegast organs that I got my hands on and at the beginning of our century I advised organists who wanted to rebuild and modernize their Ladegast organs against this sin. In terms of sound quality, I even put Ladegast organs above those from Cavaillé-Coll. "

On April 11, 1991, the German astronomer Freimut Börngen named the asteroid (29204) Ladegast after the organ builder.
