“Neighbor Rosicky”, a short story by Willa Cather, exemplifies Heidegger's concept of authentic existence. This study explores the Heideggerian features of authenticity in the character of Anthon Rosicky, drawing from Heidegger's "Being and Time." Rosicky is portrayed as someone at peace with the world, embracing life with serenity and dying with tranquility. He does not evade choice and makes decisions without regret. Satisfied with his destiny, he remains mindful of different possibilities in the world. Rosicky does not allow himself to be consumed by the mundane aspects of everyday life, enjoying each moment without being bound by the past or overly concerned about the future. Unlike many other characters in literature, he does not experience self-fragmentation, as he knows how to mend the holes to avoid destruction. This study provides a detailed analysis of how Cather's story embodies Heidegger's philosophy of authenticity and offers insights into the nature of human existence.
