. He was the third of five children of Georg Dannecker (1718–1786), a
coachman of the nobleman
Charles Alexander, Duke of Württemberg. In 1764, the family moved to
Ludwigsburg (
Baden-Württemberg). He was entered in the military school at the age of thirteen, but from 1772 to 1780 he was educated as a sculptor, together with
Philipp Jakob Scheffauer. Initially, he studied under Adam Bauer and, starting in 1775, at the military academy at Stuttgart. In his eighteenth year he carried off the prize at the Concours with his model of
Milo of Crotona. On this the duke made him sculptor to the palace (1780), and for some time he was employed on child-angels and
caryatids for the decoration of the reception rooms. In 1810, the Frankfurt banker Simon Moritz von Bethmann signed the contract for the marble version. He built a small neoclassical museum (known as the Bethmann Museum) in his garden which was completed in 1816 (today Seilerstraße 34). Open to the public, this was Frankfurt's first purpose-built museum building. Numerous visitors from all over Europe visited and admired the Ariadne. Small-scale replicas, such as those made by Meissen and Minton, were popular souvenirs and fashionable decorations. In 1853 the building and the small park were sold to the city of Frankfurt and the collection reopened in 1856 in the
Ariadneum, an octagonal annex to the Bethmann family's house (architects: Johann Georg Kayser and his son Ferdinand August). In 1941, the Bethmann family donated the museum and the collection to the city of Frankfurt. However, the sculpture was severely damaged by fire in 1943 and could only be restored in 1977–78. After the death of his schooltime friend
Friedrich Schiller, Dannecker created a bust of him, which was copied by his sculptor friend
Reinhold Begas for the
monumental Schiller statue erected on Berlin's
Gendarmenmarkt. In 1823 and 1824 he created a bust of
John the Baptist. == References ==
