The correspondence between Paul Celan (1920–1970) and Péter Szondi (1929–1971) is evidence of a long and trusting friendship. This friendship remained intact despite a severe crisis—the alleged plagiarism campaign waged against Celan by Claire Goll. Szondi's public statements in Celan's defense played a crucial role in this campaign. The letters included in this book offer a thorough chronicle of this campaign. The publication is accompanied by numerous documents and detailed factual commentary.
