Before New Jersey became known for diners, Elizabeth helped build the form itself. Jerry O’Mahony’s West Grand Street operation connected the city to one of the state’s most recognizable cultural symbols, turning local manufacturing into a lasting piece of American roadside history.
The idea of the diner, and by extension, the food truck, began with lunch wagons in the 19th century - often horse drawn carts where the owner would sell food to working class men, often men who worked overnight better known as the Lunch Car. Lunch cars were originally made by retrofitting old cargo carts to hold the merchant. The kind of cuisine lunch cars would sell varied from the seller, however the constant was the focus on easily prepared home cooked meals to be sold en masse. Of course, that also means that the diner and the food truck have a combined origin as the latter was also a natural descendant of the lunch wagon, but taken in a different direction. The term Lunch Car would fade from common use by the mid 1920s in favor for diner.
The Diner evolved from the old lunch wagons, originally in Worcester, Massachusetts, however other companies quickly sprang up. That begs the question: if diners started in Massachusetts, why is New Jersey synonymous with the diner? Jerry O’Mahony of Bayonne based his business on 977 West Grand Street, Elizabeth (now a Home Depot,) after moving from his previous location in 1925. The Jerry O’Mahony Diner Company started in 1917 in Bayonne, but quickly changed locations due to the sheer demand for O’Mahony designed cars. O’Mahony made use of the Central Railroad of New Jersey and Merrit-Chapman & Scott Corporation, a marine salvaging company, to transport his diner cars to customers across the country. The company got its start in 1913 when Jerry O’Mahony got a loan from his brother to go into business owning a highly profitable lunch car in Bayonne. O’Mahony went into business with John J. Hanf and started the company in a garage to, at first, build lunch cars, which was an immediate success. The cause for O’Mahony to constantly move to different locations came from the demand constantly exceeding his manufacturing capacity. This is how O’Mahony would eventually move on to the Elizabeth address where it stayed until the company ceased operations.
O’Mahony diners were based on the lunch car design being roughly ten to fifteen feet wide by forty feet long. Catalogues would show off the different models O’Mahoney offered prospective future restaurateurs. Diner models would use stools and countertops for seating to save space. The O’Mahony Diner Car company promised that customers would earn five to ten thousand dollars per year with their diner cars. Diner historian Richard Gutman reports that 1928 was the company’s best manufacturing year with 184 diners built for 1.5 million dollars. By the time the company dissolved, they manufactured approximately 2,000 diners. During the Second World War, the United States Government had O’Mahony’s Elizabeth factory produce chassis for trucks.
1956 – Jerry O’Mahony’s Elizabeth Property purchased by Peddie-Johnson Company of Newark, who used it for warehousing. Today, the property is a Home Depot. O’Mahony retired in 1950, and his successor decided to dissolve the Elizabeth plant. In 1957, The Wall Street Journal, reported on an incident where brokers were alleged to be manipulating Jerry O’Mahoney stocks in the aftermath of the company’s dissolution from 1950 to 1956.
There are diners built by the Jerry O’Mahony company which are still in operation to this day. Within New Jersey, the Summit Diner and the Miss America Diner are both Mahony Diners that are open to this day. Only two Jerry O’Mahony diners are in operation outside of the United States: the Super Diner at Disneyland Paris and the 1950s American Diner in Derbyshire.
It is with the help of the diners manufactured by the Jerry O’Mahony Diner Car Company that New Jersey could earn the name of the Diner Capital of the World.
