William Cullen Bryant (1794 –1878) was an American romantic poet, journalist, and long-time editor of the liberal newspaper the New York Evening Post. Bryant was a major force behind the idea that became Central Park, as well as a leading proponent of creating the Metropolitan Museum of Art. He was one of a group of founders of New York Medical College. As a writer, Bryant was an early advocate of American literary nationalism, and his own poetry focusing on nature as a metaphor for truth established a central pattern in the American literary tradition. Between the appearance of his major poem, “Thanatopsis” in 1817, and his death 61 years later, Bryant knew and corresponded with an extraordinary number of eminent men and women of the 19th century.
