- Description: Ruth Moore (1903–1989) was an important Maine author of the twentieth century. She is best known for her honest portrayals of Maine people and evocative descriptions of the state. Now primarily thought of as a regional writer, Moore was a significant literary figure on the national stage during her career. Her second novel Spoonhandle spent fourteen weeks on the New York Times bestseller list in the company of George Orwell, W. Somerset Maugham and Robert Penn Warren. In her time, Moore was hailed as "New England's only answer to Faulkner".
In 1940 Ruth met Eleanor Mayo, an aspiring writer also from Maine, and the two soon became a couple. They returned to New York where Ruth got a job with The Readers Digest while writing her first novel, The Weir, which was published in 1943.
