What was the name of F. Scott Fitzgerald's primary editor at Scribner's?

F. Scott Fitzgerald's primary editor at Scribner's was Maxwell Perkins. Perkins became Fitzgerald's editor after reading an early version of his first novel, then titled The Romantic Egotist. Although other people at the publishing house had rejected it, Perkins recognized its promise and worked with Fitzgerald on revisions.

The revised manuscript became This Side of Paradise, published in 1920. Its success established Fitzgerald as a major young writer and began one of the most important author-editor relationships in American literature. Perkins also edited The Beautiful and Damned, The Great Gatsby, and Tender Is the Night, helping Fitzgerald refine structure, pacing, and presentation.

Perkins was more than a copy editor: he was known for close developmental editing and for championing new writers. He also discovered or supported Ernest Hemingway, Thomas Wolfe, and Marjorie Kinnan Rawlings. Harold Ober, another important Fitzgerald associate, was Fitzgerald's literary agent rather than his primary Scribner's editor. Charles Scribner was associated with the publishing firm, but he was not the editor identified with Fitzgerald's books.
