Medal of Honor recipient Tom Kelley, former Georgia Gov. Carl Sanders and former major league pitcher Lou Brissie will each receive a 2013 Distinguished American Award.
The symposium was created to honor Dyess in recognition of his courage as a citizen and a soldier.
Kelley received the Medal of Honor for actions during the Vietnam War. A river assault craft he commanded fell under attack after it malfunctioned, and Kelley led the crew to safety despite a serious head wound that eventually cost him his eye.
Sanders served as governor of Georgia from 1963 to 1967, during which time he improved public schools and the university system.
Brissie, who received two Purple Hearts during World War II, pitched seven seasons in the major leagues with a shrapnel-shattered leg.
Retired Maj. Gen. Perry Smith will be the guest speaker at the event.
Admission to the 5 p.m. ceremony is free. For more information, call the museum at (706) 722-8454.
