Scholars disagree about Cather's sexual identity. Some believe it impossible or anachronistic to determine whether she had same-sex attraction, while others disagree. Researcher Deborah Carlin suggests that denial of Cather being a lesbian is rooted in treating same-sex desire "as an insult to Cather and her reputation," rather than a neutral historical perspective. Melissa Homestead has argued that Cather was attracted to Edith Lewis, and in so arguing, asked: "What kind of evidence is needed to establish this as a lesbian relationship? Photographs of the two of them in bed together? She was an integral part of Cather’s life, creatively and personally." Beyond her own relationships with women, Cather's reliance on male characters has been used to support the idea of her same-sex attraction.
