Nicholas Longworth, an American horticulturist, born in Newark, N. J., Jan. 16, 1782, died in Cincinnati, Feb. 10,1863. In his youth he was clerk in the store of an elder brother in South Carolina. At the age of 21 he emigrated to Cincinnati, where he studied law. Conceiving that Cincinnati was destined to be an important centre, he purchased considerable tracts of adjoining land, which have long since been covered by the rapidly increasing city. After about 25 years' practice he retired from professional life in order to devote himself to the cultivation of the grape, with a view of manufacturing wine, at first with little success, having used exclusively foreign vines. But about 1828 he commenced introducing native vines or their seedlings, and produced wine from two species, the Catawba and the Isabella, of a high marketable value. He had 200 acres of vineyards, besides a large wine house in the vicinity of Cincinnati. He was also favorably known by his experiments on the strawberry. At his death his property was estimated at nearly $15,000,000. He published "Buchanan's Treatise on the Grape, with an Appendix on Strawberry Culture" (1856).
