Claim to fame for Romantic composers?

All of these composers had numerous claims to fame. I can't imagine why you would ask this if not for some assignment, and I will not do your work for you. If you want to learn about these composers, there is plenty information on the Internet and in resources such as the Grove Dictionary of Music and Musicians or oxfordmusiconline.com. So that you don't get sidetracked needlessly, make sure you look under the correct names: Adolf von Henselt (not Hensel) and Clara (not Carla) Schumann.
