From Wikipedia-
Throughout Ireland and Britain, there is a long tradition of carving lanterns from vegetables, particularly the turnip, mangelwurzel, or swede. But not until 1837 does jack-o’-lantern appear as a term for a carved vegetable lantern, and the carved lantern does not become associated specifically with Halloween until 1866. Significantly, both occurred not in Ireland or Britain, but in North America. Historian David J. Skal writes,
Although every modern chronicle of the holiday repeats the claim that vegetable lanterns were a time-honored component of Halloween celebrations in the British Isles, none gives any primary documentation. In fact, none of the major nineteenth-century chronicles of British holidays and folk customs make any mention whatsoever of carved lanterns in connection with Halloween. Neither do any of the standard works of the early twentieth century.

In America, the carved pumpkin was first associated with the harvest season in general, long before it became an emblem of Halloween. The poet John Greenleaf Whittier, who was born in 1807, wrote in “The Pumpkin” (1850):
| “ | Oh!—fruit loved of boyhood!—the old days recalling, When wood-grapes were purpling and brown nuts were falling! When wild, ugly faces we carved in its skin, Glaring out through the dark with a candle within! |
