In 1919, Larsen married Elmer Imes, a prominent physicist; he was the second African American to earn a PhD in physics. After her marriage, she sometimes used the name Nella Larsen Imes in her writing. A year after her marriage, she published her first short stories.
The couple moved to Harlem in the 1920s, where their marriage and life together had contradictions of class. As Pinckney writes:
By virtue of her marriage, she was a member of Harlem's black professional class, many of them people of color with partially European ancestry. She and her husband knew the NAACP leadership: W.E.B. Du Bois, Walter White, James Weldon Johnson. However, because of her low birth and mixed parentage, and because she did not have a college degree, Larsen was alienated from the black middle class, whose members emphasized college and family ties, and black fraternities and sororities.[3]
Her mixed racial ancestry was not itself unusual in the black middle class. But many of these individuals, such as Langston Hughes, had more distant European ancestors. He and others formed an elite of mixed race or people of color, some of whom had ancestors who had been free people of color well before the American Civil War. This had given many families an advantage in establishing themselves and gaining educations in the North. In the 1920s, most African Americans in Harlem were exploring and emphasizing their black heritage.
Imes's scientific studies and achievement placed him in a different class than Larsen. The Imes couple had difficulties by the late 1920s, when he had an affair with a white woman at Fisk University, where he was a professor. Imes and Larsen would divorce in 1933.[3][4]
