Ernest Hemingway's writing was shaped by significant events such as his experiences in World War I and his time as a journalist. His participation in the war influenced much of his literary work, infusing it with themes of trauma and the human condition. Hemingway’s unique prose style, marked by conciseness and clarity, developed partly through his journalistic background. Key moments such as his encounters with notable figures of the Lost Generation, including F. Scott Fitzgerald, further enriched his perspective on life, contributing to his status as a literary icon.
