Rudy, one of six children, is Liesel's best friend. He is known for painting himself black like Jesse Owens after the 1936 Olympics and running the track at Hubert Oval. He is in love with Liesel and is constantly trying to get her to kiss him, but he only receives his kiss after it is too late. Rudy is a good student and a great athlete and often sticks up for Liesel, protecting her in any way that he knows how. Together, they steal apples and potatoes, as well as books from the mayor's house. He calls Liesel a Saumensch just like Rosa Hubermann does. Liesel calls him a Saukerl, just like Rosa calls Hans.
