A captivating portrait of Lorraine Hansberry’s life, art, and political activism--one of O Magazine's best books of April 2021 "Hits the mark as a fresh and timely portrait of an influential playwright."—Publishers Weekly In this biography of Lorraine Hansberry (1930–1965), the author of A Raisin in the Sun, Soyica Diggs Colbert considers the playwright’s life at the intersection of art and politics, with the theater operating as a “rehearsal room for [her] political and intellectual work.” Colbert argues that the success of Raisin overshadows Hansberry’s other contributions, including the writer’s innovative journalism and lesser known plays touching on controversial issues such as slavery, interracial communities, and black freedom movements. Colbert also details Hansberry’s unique involvement in the black freedom struggles during the Cold War and the early civil rights movement, in order to paint a full portrait of her life and impact. Drawing from Hansberry’s papers, speeches, and interviews, this book presents its subject as both a playwright and a political activist. It also reveals a new perspective on the roles of black women in mid-twentieth-century political movements.
