Dudley Leavitt was an American publisher. He was an early graduate of Phillips Exeter Academy in his native town of Exeter, New Hampshire, and later moved to Gilmanton where he first edited a newspaper and taught school. Within a few years, Leavitt relocated to Meredith, where in addition to teaching school and farming, he began publishing in 1797 Leavitt's Farmers Almanack, one of the nation's earliest farmers' almanacs. A polymath, Leavitt poured his knowledge of disparate fields including mathematics, language and astronomy into the wildly popular almanacs, which outlived their creator, being published until 1896. The inaugural issue of 1797 carried the title of The New England Calendar: Or, Almanack for the Year of Our Lord 1797. On the cover was the disclaimer that the new publication was "Calculated for the Meridian of Concord, Latitude 43° 14' N. Longitude 72° 45' W.: And with But Little Variation Will Answer for Any of the New England States."
