Valentine Hicks, son-in-law of abolitionist and Quaker preacher Elias Hicks, and eventual president of the Long Island Rail Road, bought land in the village in 1834 and turned it into a station stop on the LIRR in 1837. The station became a depot for produce, particularly cucumbers for a Heinz Company plant. After a blight destroyed the cucumber crops, the farmers grew potatoes. It turned into a bustling New York City suburb in the building boom following World War II.
