After Jimmy John Liautaud graduated second to last in his class at Elgin Academy in 1982, his father gave him a choice to either join the Army or start a business.[5][6] Although his father wanted him to enlist, the younger Liautaud chose the latter, and his father agreed to loan him $25,000 in exchange for a 48% stake in the business.[6][7] Initially Jimmy John wanted to open a hot dog stand, but after visiting numerous such stands throughout the summer of 1982, he realized the $25,000 would not be enough for such a venture.[8][3] After a chance encounter at a sandwich shop, Jimmy John realized that he could open a sandwich shop within his available budget by purchasing premium meats at a neighborhood market and baking his own bread. With the help of his family as tasters, he decided to put four sandwiches on his original menu. Paying $200 a month in rent, Liautaud could only afford used equipment consisting of a refrigerator, a chest freezer, an oven, and a meat slicer.[9]

On January 13, 1983, Jimmy John's Gourmet Sandwiches opened in Charleston, Illinois.[10][8] Due to the poor location of his first store, Liautaud decided to include delivery of his sandwiches to boost sales. He began by bringing samples door-to-door to the dorms of nearby Eastern Illinois University, which he had attended for one semester.[8][11]

The original Jimmy John's was located in Charleston, Illinois.
