Sources

Every claim on this site should be traceable. These are the sources — and how to check them yourself.

Letters and documents

• Brandenburg edition of Beethoven’s correspondence (Sieghard Brandenburg, ed.) — the scholarly standard for the letters quoted on Sayings & Letters and The Deafness Story.
• Heiligenstadt Testament (6/10 October 1802): original in the State and University Library Hamburg (Carl von Ossietzky Library), gift of Jenny Lind and Otto Goldschmidt (1888). English translation quoted from the public-domain Wikisource translation (translator unknown).
• Immortal Beloved letter (6–7 July 1812): manuscript in the Berlin State Library.
• Conversation books (from 1818): Deutsche Staatsbibliothek, Berlin; many destroyed by Schindler — the gaps are part of the record.
• Wegeler–Ries, Biographische Notizen über Ludwig van Beethoven (1838) — the earliest memoir; source of the Napoleon-dedication account.

Biography and scholarship

• Beethoven-Haus Bonn (beethoven.de) — chronology, catalogue, and the world’s great Beethoven archive; the authority for dates and work details used here.
• Lockwood, Lewis. Beethoven: The Music and the Life (Norton, 2003).
• Swafford, Jan. Beethoven: Anguish and Triumph (Houghton Mifflin, 2014).
• Rosen, Charles. The Classical Style (Norton, 1971/1997) — for sonata form and the Classical/Romantic turn.
• Kinsky–Halm catalogue — opus numbers and work dating.

Manuscripts and images

• Für Elise draft (BH 116, 1810) and the Beethoven-Haus Bonn collections.
• All historical images on this site come from Wikimedia Commons with their licenses recorded per file in the image credits on this page: public-domain artworks (Stieler 1820, Mähler 1804, Hardy 1792, Lange 1789) and Creative Commons photographs (Beethoven-Haus, Heiligenstadt house, Fidelio playbill) with photographer attribution.
• Generated images (the Vizlings-style character art) are labeled “AI-generated dramatization art — not a historical depiction” wherever they appear, and listed as such in the image credits on this page.

How to verify a claim

1. Check the page’s Source notes — every content page has one.
2. Dates and work details: cross-check the Beethoven-Haus Bonn work catalogue.
3. Quotations: the cited letter’s date and recipient are given; the Brandenburg edition is the scholarly text.
4. Anything flagged “reported”: the flag names the reporter (usually Schindler) and the reason for caution.
