Literature became a very important part of the Renaissance. Contributions include those of poems by Langston Hughes, Countee Cullen, Angelina W. Grimke, Jessie Redmon Fauset, and James Weldon Johnson; short stories by Nella Larsen and Zora Neale Hurston; and works by Marion Vera Cuthbert, Jean Toomer, and Ida B. Wells-Barnett.
Painting is another field that received a great number of additions by black artists in the Harlem Renaissance. Artists include Palmer Hayden, William H. Johnson, among others.
