From a Wall Street Journal online article:
Beethoven moved nearly 70 times while living in Vienna. Two of his former homes are open to the public, and many more are marked with commemorative plaques.
High above Vienna’s historic center, at the edge of the hilly Vienna Woods, the city’s Beethoven Museum, is housed in a onetime bakery complex dating back to the late Middle Ages, with an 18th-century annex containing a small apartment where Beethoven spent the summer of 1802. While living here, he composed his tragic “Tempest” piano sonata and began work on his 3rd Symphony, the “Eroica.”
LUDWIG VAN BEETHOVEN is as Viennese as apple strudel. Though born in Bonn, Germany in 1770, he moved to the Austrian capital when he was in his early 20s, and then spent the rest of his 56 years changing the course of Western music from the city on the Danube. A quirky, cantankerous celebrity in his own time, he premiered his groundbreaking symphonies and concertos in Vienna’s grand palaces, escaped the summer heat in what are now its sleepy suburbs, and moved around between dozens of supposedly squalid apartments that sprawl across much of the city.
