The 100 Most Influential Authors of the 20th Century
This list celebrates one hundred of the most widely read authors whose work shaped — and continues to shape — the literary landscape of the 20th century. It reflects a broad and inclusive perspective, recognising storytellers from across the globe and across genres, languages, and lived experiences.
From Nobel laureates to genre pioneers, from voices of revolution and exile to icons of popular fiction, these authors have reached millions of readers — sometimes across generations — through powerful ideas, unforgettable characters, and enduring narratives.
This is not a list of the “greatest” or “most awarded” writers, but rather those whose words found lasting audiences worldwide. It honours the diversity of 20th-century literature and invites you to explore signed editions of their works, now treasured by collectors and readers alike.
