A memorial service Friday will honor Barber, one of Georgia's longest-serving elected officials who died in Macon on Sunday.
Barber served as a member of the Georgia House of Representatives from 1949 to 1973. He was then elected to the PSC five times and briefly served as mayor of Commerce in the late 1980s.
Barber became the target of a bribery investigation in 1985 after representatives from a trucking company handed him an envelope containing $800. He was cleared of the charges.
Barber is remembered as an eccentric politician, sometimes sleeping in his office to avoid long commutes.
