Johann Strauss I (German: Johann Baptist Strauß, Johann Strauss (Vater); also Johann Baptist Strauss, Johann Strauss Sr., the Elder, the Father; March 14, 1804 – September 25, 1849) was an Austrian Romantic composer. He was famous for his waltzes, and he popularized them alongside Joseph Lanner, thereby setting the foundations for his sons to carry on his musical dynasty. His most famous piece is the Radetzky March (named after Joseph Radetzky von Radetz).
