While Hurston and Hughes are the two most influential writers to come out of the Harlem Renaissance, a number of other writers also became well known during this period. They include Jean Toomer, author of "Cane", a famous collection of stories, poems, and sketches about rural and urban Black life, and Dorothy West, whose novel "The Living is Easy" examined the life of an upper-class Black family. Another popular renaissance writer is Countee Cullen, who in his poems described everyday black life (such as a trip he made to Baltimore that was ruined by a racial insult). Cullen's books include the poetry collections "Color" (1925), "Copper Sun" (1927), and "The Ballad of the Brown Girl" (1927). Frank Marshall Davis's poetry collections "Black Man's Verse" (1935) and "I am the American Negro" (1937), published by Black Cat Press, earned him critical acclaim. Author Wallace Thurman also made an impact with his novel "The Blacker the Berry: A Novel of Negro Life" (1929), which focused on intraracial prejudice between lighter-skinned and darker-skinned African Americans.
