Who dated Emilie Trampusch?

Johann Baptist Strauss I (; German: [ˈjoːhan bapˈtɪst ˈʃtʁaʊs]; 14 March 1804 – 25 September 1849), also known as Johann Strauss Sr., the Elder or the Father (German: Johann Strauß Vater), was an Austrian composer of the Romantic Period. He was famous for his light music, namely waltzes, polkas, and galops, which he popularized alongside Joseph Lanner, thereby setting the foundations for his sons—Johann, Josef and Eduard—to carry on his musical dynasty. He is best known for his composition of the Radetzky March (named after Joseph Radetzky von Radetz).
