Alabama's governor plans to join Birmingham officials to unveil a marker commemorating where Martin Luther King Jr. wrote his "Letter from Birmingham Jail."
King's youngest daughter, Bernice King, is scheduled to speak at the ceremony at noon Tuesday next to the site of the old city jail.
April 16 marks the 50th anniversary of King writing the letter while jailed for his role in civil rights demonstrations. He wrote the letter after some white Alabama clergy suggested he find ways other than demonstrations to seek racial equality.
A spokesman for Gov. Robert Bentley said the historical marker was purchased by the Alabama Tourism Department and the Leadership Birmingham Class of 2012.
