Lorraine Hansberry's Unflinching Critique Of American Life

On March 11, 1959, "A Raisin in the Sun" opened on Broadway. It is one of the most important plays in the history of American theater, telling the story of the American dream and its limitations for black Americans.

"A Raisin In The Sun" was written by Lorraine Hansberry. Hansberry was a profoundly intelligent, politically radical and emotionally perspicacious 28-year-old when the play first debuted in New York.

A new documentary, entitled "Sighted Eyes | Feeling Heart," explores her life.
