She was 80.
Ms. Manly suffered a heart attack during a trip to India and died in New Delhi on Dec. 20, Edd Sheriff, the senior funeral director at Mackey Mortuary, told The Associated Press on Friday. She was in the country visiting a mission and school for widows and children.
"She loved old people and young people, it made no difference to her," said Mr. Sheriff, 67, who knew Ms. Manly for more than 40 years. "When she was with young people she acted young. When she was with old people, she'd get on their level."
Born in Greenville, Ms. Manly represented the area in the state House between 1989-1992. She pressed for legislation that would withhold state money from any institution that discriminated based on gender.
"Women are in the Gulf War -- why aren't they in The Citadel?" she said in 1991.
Four years later, the college admitted its first female cadet, Shannon Faulkner, who dropped out after less than a week. The 2007 freshman class included a record 54 women.
Ms. Manly taught at Clemson University and served on the Greenville County school board. She is survived by her husband, four children and six grandchildren.
Funeral services were scheduled for today.
