Presented Master's thesis deals with euthanasia in the novel "Ikarien" by German author Uwe Timm. The thesis highlights development of its main character Alfred Ploetz, an originator of so-called racial hygiene (German variation of eugenics). Ploetz supported the idea of performing euthanasia on severely disabled people. This was applied at massive scale in Nazi Germany from 1939 to 1945. One of the goals of this thesis is to analyze the connection between utopian notions about the creation of a new man, eugenics and euthanasia performed by Nazis, which is reflected in the life of Alfred Ploetz. Furthermore, the thesis aims to give analysis of literary means used for capturing subject matter and compare factual and fictional parts of this historical novel.
