Gertrude Franklin Horn Atherton (October 30, 1857 - June 14, 1948) was an American author. Many of her novels are set in her home state of California. Her bestseller Black Oxen (1923) was made into a silent movie of the same name. In addition to novels, she wrote short stories, essays, and articles for magazines and newspapers on such issues as feminism, politics, and war. Atherton's first publication was "The Randolphs of Redwood: A Romance", serialized in The Argonaut in March 1882 under the pseudonym Asmodeus. When she revealed to her family that she was the author, it caused her to be ostracized. In 1888, she left for New York, leaving Muriel with her grandmother. She traveled to London, and eventually returned to California. Atherton's first novel, What Dreams May Come, was published in 1888 under the pseudonym Frank Lin.
