The founder of Chick-Fil-A S. Truett Cathy died early Monday at 93. The billionaire rose from poverty and became the biggest boss of fast food chicken sandwiches. A very religious man who believed in observing Sundays as a day of rest and was open about his opposition to gay marriage. He made a lasting difference in Atlanta and on everyone who loves a tasty chicken sandwich with a pickle in the middle.

Check out his amazing legacy below.

Chick-Fil-A founder S. Truett Cathy died at the ripe age of 93 after a life full of epic success and making a difference. Chick-fil-A spokesman Mark Baldwin told The Associated Press that Cathy died at home surrounded by members of his family. The company said in a statement that preliminary plans are for a public funeral service at 2 p.m. Wednesday at First Baptist Jonesboro in Jonesboro, Georgia.

Cathy opened his first postwar diner in an Atlanta suburb in 1946 and by 1967 he had founded and opened his first Chick-fil-A Inc. restaurant in Atlanta. Over ensuing decades, the chain’s boneless chicken sandwich he is credited with inventing would propel Chick-fil-A expansion to more than 1,800 outlets in 39 states and the nation’s capital. By early 2013, the company says on its website, annual sales topped $5 billion as the chain offered up a taste of the South that went beyond chicken to such offerings as sweet tea, biscuits and gravy.

Under the religiously conservative founder, the chain gained prominence for its Bible Belt observance of Sunday — none of its hundreds of restaurants are open on that day, to allow employees a day of rest. Its executives often said the chain made as much money in six days as its competitors do in seven.

Those religious views helped win Cathy and his family a loyal following from conservative customers, but also invited protests when Cathy’s son defended the company’s donations to groups campaigning against gay marriage.

Cathy’s son, Dan, who is currently chairman and president of the chain, had told the Baptist Press in 2012 that the company was “guilty as charged” for backing “the biblical definition of a family.” Gay rights groups and others called for boycotts and kiss-ins at Cathy’s restaurants. The Jim Henson Co. pulled its Muppet toys from kids’ meals, while politicians in Boston and Chicago told the chain it is not welcome there.

The controversy later subsided.

The family-owned company has said it has had 46 consecutive years of positive sales growth. Cathy’s $6 billion fortune as the founder of Chick-fil-A puts him on the yearly Forbes magazine list of the wealthiest Americans in the country. The company has listed him on its website as its chairman emeritus after he left day-to-day operations to younger generations.

Truett Cathy began his career in the restaurant business by opening with his brother in 1946 an Atlanta diner called The Dwarf Grill, which was named for the short and stout shape of the restaurant.

He has attributed his hardworking nature — even as a little boy he made money by selling six bottles of Coca-Cola for a quarter — to growing up poor. He said,

“I’ve experienced poverty and plenty and there’s a lesson to be learned when you’re brought up in poverty,” he said in 2007. “I had to create some good work habits and attitude.”

Even well into his 80s, Cathy was actively involved in the chain’s operations, including setting up a contract with his children that said they may sell the privately owned chain in the future but the company must never go public.

Active in the business of the restaurant to his death Cathy loved his business. He was quoted in an

“Why would I retire from something I enjoy doing?” Cathy said in a 2007 interview. “I can hardly wait to get here.”
