Rudolf Johann Schock was a German tenor.
Rudolf Schock was born in Duisburg, in the Prussian Rhine Province. He sang a wide repertoire from operetta to Lohengrin, recording among others opera and lieder, doing television, radio and film work. Slim and handsome, he made many films.
His voice fell almost into the heldentenor fach but was smaller and more ardent than many voices in that category. Colored distinctly with a rich baritonal quality, Schock is described by Grove as a "lyric tenor" with a warm flexible voice, and a "strong top voice" which suited him to "heroic roles". However the same source feels that his acting left something to be desired.
When he was 18 and still continuing his musical studies that took him to Cologne, Hanover and Berlin, Schock joined the opera chorus at Theater Duisburg in the city of his birth. The Staatstheater Braunschweig cast Schock in solo roles in 1937, but his career was interrupted by his being enlisted into the army in 1940. It resumed after the war in 1945 in Hanover. In 1946, he appeared with two of the Berlin-based opera companies and in 1947 he joined the Hamburg State Opera where he was a member until 1956.
