Joseph Lux (January 1757 – 9 May 1818) was a German actor and operatic bass, who appeared especially in comic roles.
The important ensemble, which last performed in Aachen, gave rise to the Bonner Nationaltheater, which was subsidized by Elector Maximilian Franz with 15,000 Reichstalers per year and opened on 3 January 1789.
Beethoven and Bernhard Romberg were appointed kitchen boys in the roles which Lux, the singer chosen as the great king and well-known comedian, performed.
The diploma of his further promotion, which Beethoven received, dates: at the height of Rüdisheim, one will probably still have found it in his estate; at least I still saw it in his best custody in 1796.
A large seal printed in pitch in the lid of a box, fastened by some severed threads of a ship's rope, gave this diploma an honorable reputation.
