Johann Strauss, Jr. (October 25, 1825 – June 3, 1899; also known as Johann Strauss the Younger) was a composer of light music, particularly dance music and operettas. 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", and was largely responsible for the popularity of the waltz in Vienna during the 19th century.
Some of Johann Strauss's most famous works include the waltzes The Blue Danube, Kaiser-Walzer, Tales from the Vienna Woods, the Tritsch-Tratsch-Polka, and the Pizzicato Polka. Among his operettas, Die Fledermaus and Der Zigeunerbaron are the most well-known.
