The Whopper Jr was created, by accident, in 1963 by Luis Arenas-Pérez (aka Luis Arenas), the only Latino in the Burger King Hall of Fame and president and CEO of Burger King in Puerto Rico.[18] Upon the opening of the first Burger King restaurant in Carolina, Puerto Rico, the molds for the (standard) Whopper buns had not yet arrived to Puerto Rico from the United States mainland and thus there were no buns to make and sell the company's flagship Whopper offering.
