Which writer was one of the most successful novelists in the Harlem Renaissance?

The Harlem Renaissance was an intellectual, social, and artistic explosion centered in Harlem, Manhattan, New York City, spanning the 1920s. At the time, it was known as the "New Negro Movement", named after The New Negro, a 1925 anthology edited by Alain Locke. The movement also included the new African-American cultural expressions across the urban areas in the Northeast and Midwest United States affected by the Great Migration, of which Harlem was the largest.
