Abstract: (The life of Alfred Nakache, an inexhaustible source of inspiration for biographies) Two biographies published under the titles Le Nageur (Gallimard, 2023) by Pierre Assouline and Le Nageur d’Auschwitz (J’ai lu, 2024) by Renaud Leblond, both focusing on the life of the French swimmer Alfred Nakache (1915-1983), have caught the attention of the French public. These two books enabled the readers to recall significant events related to this remarkable athlete. Both texts are extremely fascinating and enlightening, presenting their own perspectives on the life and work of this athlete. We will analyze these two texts and will attempt to highlight the similarities and differences between these biographies. We will examine the structure, the style, the choice of subjects and events emphasized by the authors, showing the sub-genres these biographies belong to and demonstrating that the life of this swimmer is, in fact, an endless source of inspiration for this type of literary text.
