Jan. 15, 1929, the day the Rev. Martin Luther King Jr. was born in an upstairs bedroom at 501 Auburn Ave., has become a day when Atlanta pauses to celebrate not only King, but subsequent leaders who have devoted themselves to public service. Hands on Atlanta's 15th annual MARTIN LUTHER KING JR. SERVICE SUMMIT, continuing Wed., Jan. 16, pays tribute to King's legacy with a weeklong program of literature, discussions and films, including the premier of Honeydripper, about the birth of rock music in the Jim Crow South, and American Idealist, a documentary about Peace Corps founder Sargent Shriver. His daughter, Maria Shriver, will introduce the film. The summit culminates on the official King holiday Mon., JAN. 21, with mass volunteering. Through Jan. 21. Prices, times and locations vary. 404-979-2800. www.handsonatlanta.org.
