Besse Cooper, the world's oldest person died on Tuesday in a Monroe, Georgia nursing home at the age of 116.
Her son Sidney Cooper said his mother had been ill recently with a stomach virus. On Tuesday he said she was put on oxygen in her room and died at about 2 p.m.
Sidney Cooper told the Associated Press that his mother recently had her hair done: "With her hair fixed it looked like she was ready to go."
Robert Young, Guinness senior consultant for gerontology, told the Associated Press: "It's a sad day for me. At that age she was doing really well, she was able to read books."
Besse Cooper was the first Georgian to hold the world record. She was born in Tennessee and moved to Georgia during World War I to work as a teacher.
The title of world's oldest person now belongs to 115-year-old Dina Manfredini, of Johnston, Iowa.
