Which of the following authors is NOT known for writing short stories?

T.S. Eliot is primarily recognized for his contributions to poetry and plays rather than short stories. He is a leading figure in modernist literature, famously known for his poems such as "The Waste Land" and "The Love Song of J. Alfred Prufrock." While he did write some prose and essays, including critical works on poetry and literature, his reputation does not stem from short fiction.

In contrast, the other authors listed are all celebrated for their mastery of the short story form. Eudora Welty, for example, is acclaimed for her poignant and evocative short stories that often explore the American South. Flannery O'Connor is renowned for her unique voice in the Southern Gothic genre, delivering impactful narratives in short form. O. Henry, famous for his twist endings, is synonymous with American short stories and is cherished for his clever and engaging tales. These authors have produced significant volumes of short fiction, making them distinct from T.S. Eliot in this regard.
