Jason Carter, himself a former state senator and one-time Democratic nominee for governor, called his grandmother “the best politician in the family”, a distinction Jimmy Carter never disputed.
When she died, Mr Carter said in a statement that she’d been “my equal partner in everything I ever accomplished”.
Celebrated as an active first lady who championed then little-discussed issues of mental health, Mrs Carter’s reputation only grew, along with her husband’s, once they left the White House.
Losing his 1980 reelection bid to Republican Ronald Reagan, Mr Carter was widely dismissed as a failure. However, the couple went on to build a global network of charity activities and earned plaudits for their humble lifestyle.
The Carters married in 1946 and held the record of longest-wed presidential couple.
Throughout Mr Carter’s long political career, his wife was at the heart of his campaigns. During the 1977 to 1981 White House term, Mrs Carter worked to raise the status of the first lady’s office.
“She attended Cabinet meetings and major briefings, frequently represented the chief executive at ceremonial occasions and served as the president’s personal emissary to Latin American countries,” according to the White House website.
She was born in Plains on Aug 18, 1927, as the first of four children. At 13 her father died and she worked alongside her mother, who became a dressmaker to make ends meet.
She met Mr Carter in 1945 while she was in college and he was on leave from the US Naval Academy in Annapolis.
Mrs Carter’s farewell began Monday when past and present agents from the US Secret Service, which guards presidential families, escorted her coffin to the Jimmy Carter Presidential Library and Museum in Atlanta. The public was invited to pay their last respects.
Her funeral will take place on Wednesday at Maranatha Baptist Church in Plains, Georgia where the couple worshipped after they left the White House.
