Jakub Jan Ryba

Jakub Šimon Jan Ryba (surname also Poisson, Peace, Ryballandini, Rybaville;[1] 26 October 1765 – 8 April 1815) was a Czech teacher and composer of classical music.

Being popular among local inhabitants for performing music, he was quite happy there, but after some hesitation he accepted a schoolteacher position in Rožmitál pod Třemšínem.

In 1796, he wrote his most famous work, Czech Christmas Mass "Hey, Master!"

accommodata in linguam bohemicum musicam), also as a consequence of a reconciliation with the local pastor.

An insufferable lack of money, the hostility of his superiors and total exhaustion led him to commit suicide at Voltuš near Rožmitál pod Třemšínem.
