Lorraine Vivian Hansberry was a playwright and writer. She was the first African-American female author to have a play performed on Broadway. Her best known work, the play A Raisin in the Sun, highlights the lives of Black Americans living under racial segregation in Chicago.

At the age of 29, she won the New York Drama Critics' Circle Award — making her the first African-American dramatist, the fifth woman, and the youngest playwright to do so. Hansberry's family had struggled against segregation, challenging a restrictive covenant and eventually provoking the 1940 Supreme Court case Hansberry v. Lee.
