Two celebrated authors will discuss their work during a free public Jan. 22 event to celebrate the 50th anniversary of the Rev. Dr. Martin Luther King Jr.’s “I Have a Dream” speech.

The event, called “Voices of the Dream,” is sponsored by Wayne State University Law School’s Damon J. Keith Center for Civil Rights, and will be held from 4:30 to 6:30 p.m. in the Spencer M. Partrich Auditorium at the Law School, 471 W. Palmer, Detroit.

The first speaker, Dr. Clarence B. Jones, is a former speechwriter and legal counsel to King. Jones will discuss and sign his latest book, “Behind the Dream: The Making of the Speech that Transformed a Nation.”

Jones began working with King in 1960, and stayed with him as an advisor and close friend throughout the remainder of King’s life, helping him draft the “I Have a Dream” speech.

The second speaker, Gregory Reed, earned his J.D. in 1974 and his LL.M. in 1978 from Wayne Law. He is founder of the Keeper of the Word Foundation and a former attorney to Rosa Parks. He’ll be signing copies of his new, award-winning book, “Obama Talks Back: Global Lessons – A Dialog with America’s Young Leaders.”

The book features thousands of letters from students to President Obama, and his responses.
