Peter Buck, one of the co-founders of Subway, has died. He was 90.

Dr. Buck died on Nov. 18 in Danbury, Connecticut, according to theNew York Times.

Subway’s official Twitter accountalso confirmed the news of Dr. Buck’s death, writing, “Our co-founder, Dr. Peter Buck has passed. He was 90. A kindhearted physicist & philanthropist, Dr. Buck made a lasting impact, leaving behind a spirit of hard work & dedication across nearly 40,000 locations. His legacy continues through Subway®, a brand he worked hard to build.”

A cause of death has not been announced.

Dr. Buck, a nuclear physicist, helped co-found one of the most well-knownfast-food chainsin the world in the 1960s.

“One day, my wife and I and the kids were having a picnic in the backyard, and we had invited our friends Sal and Carmela DeLuca, and young Fred DeLuca, too,” Dr. Buck said in aYouTube videoexplaining the story of Subway’s origins. “At some point during the picnic, Fred came to me and said, ‘Hey Pete, what can I do to get some money so I can go to college?’ … I said, ‘Let’s open a submarine sandwich store.’ "

PerSubway’s website, Dr. Buck gave DeLuca $1,000 to open a sandwich shop to “help pay his tuition,” and the pair opened their first sandwich shop in Bridgeport, Connecticut, in 1965. The restaurant chain was originally founded under the name “Pete’s Super Submarines,” but was changed to Subway three years later, according toCBS News.
