# Jerry O'Mahony Diner Company

The Jerry O'Mahony Diner Company of Elizabeth, New Jersey, was a manufacturer of roadside diners from 1917 to 1952. The company produced some 2,000 of the long, narrow, primarily metal buildings, perhaps more than any other firm. Prefabricated in a factory and trucked to their locations, the diners resemble and are often confused with railroad rolling stock. The company's motto was "In our line, we lead the world".

## History

Jerry O'Mahony (1890–1969) of Bayonne, New Jersey, is credited by some to have made the first "diner". In 1912, the first lunch wagon built by Jerry and Daniel O'Mahoney and John Hanf was bought for $800 by restaurant entrepreneur Michael Griffin and operated at Transfer Station in Hudson County, New Jersey. The wagon helped spark New Jersey's golden age of diner manufacturing.
It is estimated that about 20 remain in the United States as of 2022.

* Bishop's 4th Street Diner, in Newport, Rhode Island, was in continuous use in Newport from 1967 to 2022. Previously located on Route 6 in Swansea, Massachusetts as "The Princeton Diner." It was moved to Admiral Kalbfus Road in Newport in 1967 as "The Galley Diner," then "The 4th Street Diner" (a tongue-in-cheek name, since no 4th Street exists in Newport). In 1998, renamed "Bishop's 4th Street Diner" after a new owner. The diner closed in 2022 to make way for a Seasons Market and gas station. After its closure, the diner was sold in October 2022 and moved to New Hampshire, where new owners plan to eventually reopen it as a restaurant.
