This month's final post in our series celebrating African-American artists and writers brings together two greats of the Harlem Renaissance: James Weldon Johnson and Aaron Douglas. Johnson was multi-talented: an educator, writer, attorney and musician, he was the author of "Lift Every Voice and Sing," a leader of the NAACP, and the first African-American professor at New York University. God's Trombones is considered one of his most important works. Douglas was one of the leading artists of the Harlem Renaissance. He developed a distinctive style that blended modernism with African influences and was highly influential in the development of later African-American artists.
