As a young person, Lorraine became an influential American playwright and writer, best known for her groundbreaking work "A Raisin in the Sun," which made her the first Black woman to have a play produced on Broadway. In the 1950s, Hansberry identified as a feminist and was a closeted lesbian. She joined the New York chapter of the Daughters of Bilitis, contributing essays to its newsletter, The Ladder, under the pen name “L.H.N.”
Her lesbian identity and 1964 divorce from Nemiroff were not widely known at the time of her death. It was not until the 1980s that feminist scholars connected her feminist vision with her lesbian identity.
