Which author is known for the use of magical realism in American literature?

The recognition of Gabriel García Márquez as a key figure in magical realism is grounded in his profound influence on the genre, particularly through works like "One Hundred Years of Solitude." Magical realism blends fantastical elements with realistic settings, allowing the extraordinary to coexist with the mundane in a way that resonates deeply with Latin American culture and experiences. Márquez’s narrative style intricately weaves the magical into the fabric of everyday life, crafting stories that challenge traditional perceptions of reality.

While other authors mentioned have made significant contributions to literature, their works do not primarily embody the characteristics of magical realism. John Steinbeck is known for his poignant social commentary and depictions of American life, particularly during the Great Depression. Mark Twain is celebrated for his satire and realism, focusing on the intricacies of American society and its characters without incorporating the magical elements that define magical realism. Isabel Allende, although a prominent author known for her own magical realist works, is often recognized as a key figure within Latin American literature rather than American literature as defined in the context of this question. Therefore, Gabriel García Márquez stands out as the quintessential author associated with magical realism in the American literary canon.
