How it started

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.
