U.S. Rep. John Lewis of Atlanta will deliver the keynote address Friday at DeKalb County's Annual Martin Luther King Celebration Program, according to a release from the county's public information office.

The event will be held at the Maloof Auditorium located at 1300 Commerce Drive in Decatur from 11:30 a.m. to 1 p.m.

One DeKalb - One Community - One Dream  is the theme for the free celebration intended to honor the life of the Rev. Dr. Martin Luther King, Jr. presented by DeKalb County Chief Executive Officer Burrell Ellis and the Board of Commissioners. The event is open to the public.

Burke Brennan, the county's chief communications officer, said in addition to the keynote remarks, the celebration will feature choral performances and other speakers in what is expected to be an hour-long tribute to King's legacy.

Lewis led the Student Nonviolent Coordinating Committee and was the youngest speaker at the 1963 March on Washington for Jobs and Freedom, where Martin Luther King, Jr. delivered his famous “I Have a Dream” speech.

The 2011 tribute marks the 27th consecutive year DeKalb County will host the employee-planned event honoring the life and legacy of Dr. King, county officials said. Jan. 17 marks the 25th anniversary of the Martin Luther King Jr. federal holiday. In celebration of the day, many groups and charities organize volunteer and service opportunities.
