The Beethoven Museum Heiligenstadt is the address where Beethoven wrote his brothers a letter admitting he was going deaf and had thought about ending his life. He dated it 6 October 1802, added a postscript four days later, and never sent it. It is called the Heiligenstadt Testament, though it is a letter and not a will, and it lay among his papers until friends found it after his death. He had come out to this wine village that spring on a doctor's advice.
The doctor was Johann Adam Schmidt, an eye and ear specialist who hoped the village's mineral bath would help. It did not. The building was a country baker's house around a small courtyard, and the city opened rooms in it as a memorial in 1970. The letter on show is a reproduction, because the original has been in a Hamburg library since 1888. The strongest thing here is a listening station that plays music through Beethoven's hearing as it failed, until almost nothing comes through.
