The most widely accepted origin story begins in 1929, when streetcar workers at Electric Street Railway in New Orleans went on strike. The owners of Martin Brothers’ French Market and Coffee Stand, Bennie and Clovis Martin, decided to feed the strikers.
The two brothers were streetcar conductors turned restauranteurs, and they put their support firmly behind the striking employees. They provided sandwiches filled with potatoes, gravy, and sometimes bits of roast beef.
It was called the “poor boy” sandwich, and it took on a life of its own in New Orleans, continuing to evolve into the po’ boy sandwiches we know today.
