A spokesman for Chick-fil-A has said that the restaurant chain's founder, S. Truett Cathy, has died aged 93, the Associated Press reported.
Chick-fil-A famously famously operates a policy where its restaurants remain closed on Sundays.
Cathy was a devout Southern Baptist who taught Sunday school classes for 50 years, and the "closed on Sunday" policy was an extension of his faith.
A statement from the company confirmed that their restaurants will continue the policy and will remain in private hands.
Cathy was replaced as Chick-fil-A president by his oldest son Dan in 2001, but remained chairman emeritus until his death.
In 2012, Chick-fil-A and the Cathy family courted controversy with their vocal opposition to gay marriage.
