Erich Kästner is a phenomenon – his books do not age and continually find a new, enthusiastic audience. The fact that he is now perceived not only as a children's author but also as a serious novelist is also thanks to Sven Hanuschek. For Kästner's 100th birthday, he published his groundbreaking biography and has since completed the picture of Erich Kästner with surprising first and new editions: "Der Gang vor die Hunde," the original version of "Fabian," became a bestseller, as did the "Blaue Buch" with the secret diary entries from 1941 to 1945. For Kästner's 125th birthday (and 50th death anniversary), Sven Hanuschek updates his biography. It presents Erich Kästner as one of the most significant authors and intellectuals of his generation.
