Subway’s last surviving founder Peter Buck dead at 90

Peter Buck, the billionaire cofounder of Subway, one of the largest restaurant chains in the world, has died at 90 years old.

Report informs, citing Forbes, that Buck died on November 18, according to a statement from the company. His cause of death was not immediately revealed.

Buck gave the chain its wings by making the crucial investment of $1,000 to his friend’s son, Fred DeLuca, in 1965. Then working as a nuclear physicist, Buck figured the sub shop could help pay the 17-year-old high school graduate’s way through college. DeLuca used the money to launch “Pete’s Subway Submarines,” named in Buck’s honor.
