HARDTMUTH, Joseph

(b. 1758 Asparn an der Zaya, d. 1816 Wien)

Austrian architect and inventor. Joseph Hardtmuth, Joseph Kornhäusel and Franz Engel were the architects of the princes of Liechtenstein. They created an architecture of follies, pavilions, miniature palaces and all the other accoutrements of an English garden in Feldsberg (Valtice) and Eisgrub (Lednice). The park was also a hunting ground, and this led to a whole series of buildings that were used during and after hunts.

Hardtmuth’s major architectural works are: the Palais Liechtenstein at Herrengasse in Vienna (1789-91, destroyed between 1913 and 1917); Burg Janùv Hrad (Lednice, 1801-02); Dianatempel, (Valtice, 1810-12); Reistenberg colonnade (Valtice, 1810-12); Schloss Pohanska (Breclav, 1810-12).

As an inventor, in 1789, Hardtmuth invented a new kind of earthenware with a lead-free glaze for the tableware production, the so-called Vienna ware. In 1810, he invented an artificial pumice and years later, a version of stoneware which was used to make mortars, funnels and other utensils. A flexible, unbreakable blackboard was also produced.

In 1792, Hardtmuth established a pencil factory in Vienna after he succeeded in creating an artificial graphite pencil by mixing powdered graphite with clay. Until that time, whole pieces, cut from graphite, were glued in between wood and were imported from England. With the new method, graphite of inferior quality could be used in pencil manufacturing, lowering the price and making the product more accessible for the masses. His company Koh-i-Noor Hardtmuth still exists.

The Hansenburg castle belongs to the typical follies found in English gardens. It corresponds to the traditional canon of landscape architecture. Ruined castles were built at several of the Liechtenstein estates in Lower Austria and Moravia. The four-winged complex of the Hansenburg with its massive round towers was the largest of these. Its interior housed a great Knights’ Hall and a collection of weapons.

Reistenberg colonnade

One of the most interesting collections of Neoclassical and Romantic buildings can be found situated along the Thaya on the border between Austria and Moravia. Along the seven-kilometer avenue which connected their residences at Feldsberg (Valtice) and Eisgrub (Lednice), the princes of Liechtenstein laid out a landscape garden on the English model with buildings from a variety of different architectural styles. From the 13th century to 1945 both locations were inextricably linked to the House of Liechtenstein, and in the 16th century Feldsberg became the main seat of the princes, along with their summer residence at Eisgrub. It was towards the end of the 18th century that Prince Johann Josef I began to regulate the countryside, laying out the gigantic landscape garden that still exists today.

The Reistenberg colonnade is a variation on the colonnade theme. It was begun in 1812 by Hardtmuth and completed by his successor Joseph Kornhäusel, after Hardtmuth retired from royal service. The attic extends for four intercolumniations at both sides of the triumphal arch, the outermost supports of the structure featuring the same design as the arch itself. They contain staircases leading up to the terrace on top of the attic.

The traditional triumphal arch of the Temple of Diana was built by Hardtmuth, but the interior was completed by Kornhäusel. A great hall is located on its top floor, reached by a spiral staircase. The room served as a breakfasting hall after the hunt.

The model for this park was principally provided by the garden at W�rlitz near Dessau. Among the most impressive buildings in the park is the 68-m-high Turkish Tower which Joseph Hardtmuth built in 1797 as a viewing platform by the Swan Lake (excavated in 1790). The podium of the octagonal tower is built on a square ground plan, whose perimeter is marked by an arcade. Each of the three arches of the arcade corresponds to three round arched windows in the floor above. Piers continue past the cornice to become small towers, and the individual floors of the tower are separated from each other by external galleries.
