Willa Sibert Cather born Wilella Sibert Cather; December 7, 1873 – April 24, 1947) was an American writer known for her novels of life on the Great Plains, including O Pioneers!, The Song of the Lark, and My Ántonia. In 1923, she was awarded the Pulitzer Prize for One of Ours, a novel set during World War I. Cather achieved recognition as a novelist of the frontier and pioneer experience. She wrote of the spirit of those settlers moving into the western states, many of them European immigrants in the nineteenth century. Common themes in her work include nostalgia and exile. A sense of place is an important element in Cather's fiction: physical landscapes and domestic spaces are for Cather dynamic presences against which her characters struggle and find community.
