ATLANTA - S. Truett Cathy, the founder of the Chick-fil-A fast-food chain known for its chicken sandwiches as well as for its president's public opposition to gay marriage, died on Monday at age 93, the company said.
Cathy, the billionaire chairman emeritus of the privately held Atlanta-based company known for requiring the chain's restaurants to close on Sundays in keeping with its Christian principles, died peacefully at his home in Clayton County, Georgia, a company spokeswoman said.
"Our city is saddened by the loss of Truett Cathy," Atlanta Mayor Kasim Reed said on Twitter. "His legacy will live on through his family and good works."
Cathy opened the first Chick-fil-A in 1967 in his native Georgia, where he is credited with creating the recipe for the company's signature boneless chicken sandwich and helping to pioneer the idea of putting restaurants in shopping malls.
A devout Southern Baptist, he earned both admiration and disdain for his unapologetic mix of religion and business as he built a family-owned empire that now includes more than 1,800 locations in 40 states and Washington, D.C.
Chick-fil-A netted $5 billion in sales in 2013, according to the company.
"People appreciate you being consistent with your faith," he once told the Atlanta Journal-Constitution. "It's a silent witness to the Lord when people go into shopping malls, and everyone is bustling, and you see that Chick-fil-A is closed."
The chain made headlines in 2012 when president Dan Cathy - the founder's son - told an online religious newspaper that he supported "the biblical definition of the family unit" and that supporters of gay marriage were "arrogant."
His statements ignited a cultural firestorm, triggering protests that included "kiss-ins" by same-sex couples outside some stores and criticism from the mayors of Chicago and Boston.
Social conservatives and fans of the chain's chicken and waffle fries countered with their own push to get people to eat at Chick-fil-A in a sign of support for Dan Cathy's stance and his right to voice it.
Chick-fil-A issued a statement as it sought to move past the controversy, saying its culture was "to treat every person with honour, dignity and respect - regardless of their belief, creed, race, sexual orientation or gender."
Truett Cathy was also known for his philanthropy, which focused largely on programs for foster children and other youth.
His survivors include his wife of 65 years, Jeannette McNeil Cathy, three children, 19 grandchildren and 18 great-grandchildren.
A public funeral service will be held at a church in Jonesboro, Georgia, on Wednesday, the company said.
