20 000 Forint Teréz Brunszvik

Teréz Brunszvik (1775–1861) founded the first kindergarten in Hungary in 1828, predating Friedrich Fröbel's widely credited German model by nearly a decade — a priority dispute that Hungarian historians have pressed for two centuries with only partial international acknowledgment. She was a close friend of Beethoven, who dedicated his two piano sonatas Op. 78 to her, though whether their relationship extended beyond friendship remains genuinely contested among biographers. The Magyar Nemzeti Bank has issued this coin in 2025, the year marking the 250th anniversary of her birth.
