Why can F. Scott Fitzgerald also be considered a social historian?

I hope this helps :)

Explanation:

The success of his first novel, “This Side of Paradise” (1920), made him an instant celebrity. His third novel, “The Great Gatsby” (1925), was highly regarded, but “Tender is the Night” (1934) was considered a disappointment. Struggling with alcoholism and his wife’s mental illness, Fitzgerald attempted to reinvent himself as a screenwriter. He died before completing his final novel, “The Last Tycoon” (1941), but earned posthumous acclaim as one of America’s most celebrated writers.
