The Genius Of Beethoven

Episode One

Beethoven was the grandson of a musician of Flemish origin named Lodewijk van Beethoven (1712–1773). Beethoven was named after his grandfather, as Lodewijk is the Dutch counterpart of Ludwig. Beethoven's grandfather was employed as a bass singer at the court of the Elector of Cologne, rising to become Kapellmeister (music director). He had one son, Johann van Beethoven (1740–1792), who worked as a tenor in the same musical establishment, also giving lessons on piano and violin to supplement his income. Johann married Maria Magdalena Keverich in 1767; she was the daughter of Johann Heinrich Keverich, who had been the head chef at the court of the Archbishopric of Trier.
