History:

The organ was built 1743-1746 by organbuilder Zacharias Hildebrandt.
Hildebrandt reused the old decorated organ case of the old organ built
by Thayssner in the years 1696-1705. The organ was proofed ("Orgelprobe")
on September 27th, 1746 by Johann Sebastian Bach and Gottfried Silbermann
(Hildebrandt was a pupil of G. Silbermann). J. S. Bach also worked as an
organ consultant for this project. In the 19th century the organ was
extensively rebuilt. In 1933 the action was electrified by E. F. Walcker
organbuilders. 66 percent of the pipes by Hildebrandt are lost and a lot
of the surviving pipes are not on their original location on the chest. So
it is not a Hildebrandt-organ but more or less an organ with Hildebrandt-pipes
and an old Thayssner-case. In the year 1992 there was a symposium at Naumburg
which decided together with a commission of organ consultants/organists to
reconstruct the organ to its original state dating from 1743-46. This work is
currently done by organbuilder Hermann Eule from Bautzen. It is planned, that
in September 1996 (250 years after its completion) the Rueckpositiv will be
playable again. (Now, 1999, the Rueckpositiv is playable.) In 2000 the whole
organ was restored and playable again.

1696/1705 organ built by Zacharias Thayssner

1743    J. S. Bach made a proposal for a repair of the organ
    to the local authorities

1743/46 Totally new organ built in the old case by Zacharias Hildebrandt

1834    Organ repaired by organbuilder Friedrich Beyer from Naumburg:
    some stops revoiced, pitch raised 1 halftone (pies shortened)

1865    Organ repaired by Friedrich Ladegast, some changes made by Beyer
    removed, Posaune 32' exchanged by Violonbass 32'

1912/15 Oskar Ladegast (son of Friedrich L.): chests of the Oberwerk
    replaced by pneumatic cone chests, pitch changed (pipes shortened
    and changes in the key action), some Hildebrandt stops removed
    and replaced by 'modern' stops

1928    Plans to rebuilt the whole organ (reusing some Hildebrandt stops)
    (organist Wilhelm Nichterlein)

1931    Organ visited by Chisthard Mahrenholz as consultant: recommended
    to restore the organ to its original (Hildebrandt) state

1931/33 Organ rebuilt by organbuilders Walcker: original pipes from
    Hildebrandt retained, also the chests and some parts of the
    old console, but: new electropneumatic action with a new console,
    pipes shortened again (3rd time), new pipes added
    Before and during the restauration the whole organ in all details
    was photographed, these photos now are an important historic document.

1964    First trial of organbuilders Eule to restore the organ
    towards its original state
