Johann Strauss II (or Johann Strauss the Younger, or Johann Strauss Jr.) (October 25, 1825 - June 3, 1899) was an Austrian and German composer known especially for his waltzes, such as The Blue Danube.
Radetzky March, Op. 228, is a march composed by Johann Strauss Sr. in 1848. It was dedicated to the Field Marshal Joseph Radetzky von Radetz, and became quite a popular march among soldiers. It has been remarked that its tone is more celebratory than martial- Strauss was commissioned to write the piece for a celebration of Radetsky's victory at the Battle of Custoza.
