Johann Baptist Strauss II (/straʊs/; German: [ˈjoːhan bapˈtɪst ˈʃtʁaʊs]; 25 October 1825 – 3 June 1899), also known as Johann Strauss Jr., the Younger or the Son (German: Johann Strauß Sohn), was an Austrian composer of light music, particularly dance music and operettas, as well as a violinist. He composed over 500 waltzes, polkas, quadrilles, and other types of dance music, as well as several operettas and a ballet.
In his lifetime, he was known as "The Waltz King", as he played a major role in popularizing the waltz in the 19th century. Some of Johann Strauss's most famous works include "The Blue Danube", "Kaiser-Walzer" (Emperor Waltz), "Tales from the Vienna Woods", "Frühlingsstimmen", and the "Tritsch-Tratsch-Polka". Among his operettas, Die Fledermaus and Der Zigeunerbaron are the best known.
