Lorraine is from the historical French province of Lorraine — itself from the medieval Latin Lotharingia, the kingdom of Lothair II established 855 CE. Lorraine Hansberry (1930-1965) — *African American playwright whose A Raisin in the Sun (1959) — written when she was 28 — became the first play by a Black woman ever produced on Broadway and the first Broadway play directed by a Black director (Lloyd Richards). Won the New York Drama Critics' Circle Award for Best Play (1959), beating works by Tennessee Williams, Eugene O'Neill, and Archibald MacLeish — the youngest American and first Black writer to win the prize. The play's title is from Langston Hughes's poem Harlem: "What happens to a dream deferred?". Died of pancreatic cancer at 34. A top-100 US baby name from 1933 to 1957*.
Subject of Sighted Eyes/Feeling Heart (2017 PBS American Masters documentary).
