A 99-year-old woman, thought to be the world's oldest primary school student, died peacefully at home in Kenya, according to her grandson.
After attending class on Wednesday, Priscilla Sitienei began experiencing health complications.
She and her 12-year-old classmates had been studying for final exams, which were set to begin next week.
Ms Sitienei's story sparked a film and accolades from Unesco, the United Nations' cultural and educational agency.
She grew up in a British-occupied Kenya and witnessed her country's struggle for independence.
Last year, she told Unesco that she wanted to encourage young mothers to return to school.
"I wanted to set an example not only for them, but for other girls around the world who are not in school," she explained. "Without education, there is no difference between you and a chicken."
She started at Leaders Vision Preparatory School in 2010, but she has been a midwife in her village of Ndalat in the Rift Valley for over 65 years.
She had even assisted in the delivery of some of her own classmates, who were then aged 10 to 14.
She told the BBC in 2015 that she was finally learning to read and write, something she never had as a child. She was affectionately known as "Gogo," which means grandmother in the local Kalenjin language.
She frequently confronted children who were absent from school and asked them why.
"They say they're too old," she explained. "I tell them, 'Well, I'm at school, and you should be, too.'"
"I see lost children, children without fathers, going round and round in circles, hopeless. I want to motivate them to attend school "She continued.
'Her message endures.'
The school initially turned her down, but they quickly realized how dedicated she was to learning.
Her story was told in the French film Gogo, which provided her with the opportunity to visit France and meet first lady Brigitte Macron.
Patrick Pessis, the film's co-writer, paid tribute on Twitter, saying, "Her message about girls' education lives on."
Another Kenyan, the late Kimani Maruge, holds the current Guinness World Record for the world's oldest primary school pupil.
He started school in 2004 at the age of 84 and died five years later.
