In 1938, Hansberry's family moved to a white neighborhood and was violently attacked by neighbors. They refused to move until a court ordered them to do so, and the case made it to the Supreme Court as Hansberry v. Lee, ruling restrictive covenants illegal.

While at school, she changed her major from painting to writing, and after two years decided to drop out and move to New York City.
