Question: Which correspondent of Frederick Goddard Tuckerman was an American essayist, lecturer, and poet who led the transcendentalist movement of the mid-19th century?
Context: The history of Bridgeport, Connecticut was, in the late 17th and most of the 18th century, one of land acquisitions from the native inhabitants, farming and fishing.  From the mid-18th century to the mid-19th century, Bridgeport's history was one of shipbuilding, whaling and rapid growth.  Bridgeport's growth accelerated even further from the mid-19th century to the mid-20th century with the advent of the railroad, Industrialization, massive immigration, labor movements until, at its peak population in 1950, Bridgeport with some 159,000 people was Connecticut's second most populous city.  In the late 20th century, Bridgeport's history was one of deindustrialization and declining population, though it overtook Hartford as the state's most populous city by 1980.

Mulberry Hill is a historic plantation house located near Randolph, Charlotte County, Virginia.  The original section dates to the 18th century and forms the slightly projecting, gable-end, two-story front center pavilion.  Flanking this center section are single-bay two-story wings added in the mid-19th century.  At the same time, a two-story rear wing was added.  The front facade features a mid-19th century porch with a full Doric order entablature supported on octagonal Doric columns.  Also on the property are the contributing Judge Paul Carrington's office building, a brick kitchen, a frame spinning house, a dairy, a smokehouse, a privy, and servants' quarters.  It was the home plantation of 18th century political official and jurist Paul Carrington (1733–1818).  He is buried on the plantation grounds.

Frederick Goddard Tuckerman (February 4, 1821 – May 9, 1873) was an American poet, remembered mostly for his sonnet series.  Apart from the 1860 publication of his book "Poems", which included approximately two-fifths of his lifetime sonnet output and other poetic works in a variety of forms, the remainder of his poetry was published posthumously in the 20th century.  Attempts by several 20th century scholars and critics to spark wider interest in his life and works have met with some success and Tuckerman is now included in several important anthologies of American poetry.  Though his works appear in 19th century anthologies of American poetry and sonnets, this reclusive contemporary of Emily Dickinson, sometime correspondent of Nathaniel Hawthorne, Ralph Waldo Emerson and Henry Wadsworth Longfellow, and acquaintance of Alfred, Lord Tennyson, remains in relative obscurity.
