Pasqualati House

The house was built in 1797 by Peter Mollner [de] for Empress Maria Theresa's personal physician, Joseph Benedikt, Baron Pasqualati von Osterberg (1733-1799), by joining two smaller residences and augmenting these to produce the present stately apartment block.

One of the older buildings housed a stonemason's workshop, while the other numbered among its tenants Count Leander Anguissola [de], imperial chief engineer, and Johann Jakob Marinoni [de], a court mathematician, who together published a plan of Vienna while holding teaching posts at the Military Engineering Academy, under whose auspices they gave lectures in the house.

[3] In 1770 the composers Florian Gassmann and his student Antonio Salieri lived in one of these smaller residences, known then as the “Schmidisches Haus.”[4] Joseph Benedikt's son, Johann Baptiste, Baron Pasqualati von Osterberg (1777-1830) inherited the house, together with his three siblings, on his father's death.

Between 1804 and 1815, Beethoven twice took up residence in the present building (1804–08 and 1810–14), with some of his most important works, including the Fifth and Sixth Symphonies, Für Elise, the Archduke Trio and his only opera, Fidelio, being composed at the Pasqualati House.
