Question: Who managed the 5,000 acre estate of Thomas Jefferson?
Context: Monticello was the primary plantation of Thomas Jefferson, the third President of the United States, who began designing and building Monticello at age 26 after inheriting land from his father.  Located just outside Charlottesville, Virginia, in the Piedmont region, the plantation was originally 5000 acre , with Jefferson using slaves for extensive cultivation of tobacco and mixed crops, later shifting from tobacco cultivation to wheat in response to changing markets.  Due to its architectural and historic significance, the property has been designated a National Historic Landmark.  In 1987 Monticello and the nearby University of Virginia, also designed by Jefferson, were together designated a UNESCO World Heritage Site.  The current nickel, a United States coin, features a depiction of Monticello on its reverse side. Long Hill is a 114 acre estate in Beverly, Massachusetts and is managed by the Trustees of Reservations.  From 1916 to 1979, the estate was the summer home of Ellery Sedgwick, author and editor of "The Atlantic Monthly".  The estate contains a Federal style home with formal gardens, 2 mi of hiking trails, woodlands, meadows and an apple orchard.  The 5 acre of cultivated gardens and 100 acre of woodland grounds are open to the public daily. Edmund Bacon (1785–1866), was the business manager and primary overseer for 20 years for Thomas Jefferson, 3rd President of the United States, at Monticello.  Among some of his other business duties, Bacon supervised the daily chores and activities of farming and ranching at Monticello along with Jefferson's nail forge.  His duties included supervising and providing supplies and other needs for Jefferson's slaves.  When he retired, Bacon moved to Kentucky and was discovered by the author Rev. Hamilton Pierson, who made use of his memoirs and letters to write a book about Jefferson's personal life and character.  The memoirs of Bacon's life at Monticello has given much insight into the daily activities there, as well as into Jefferson's life and personality.

The Thomas Jefferson Foundation Medal in Architecture recognizes individuals for distinguished contributions to the field of architecture.  The Medal in Architecture has been jointly awarded each year by the Thomas Jefferson Foundation at Monticello and the University of Virginia School of Architecture since 1966.

Pantops Farm is a historic house at 400 Peter Jefferson Road in Charlottesville, Virginia.  It consists of a Colonial Revival main house, a guest house, and a building resembling a silo in appearance.  This complex was designed by Benjamin Charles Barker and built in 1937 for James Cheek, whose family made its fortune in Maxwell House coffee.  Its buildings, in particular the guest house and silo, were designed to appear as if they were older buildings that had been repurposed.  The property is a small remnant of an estate that was once owned by Thomas Jefferson.  It is now owned by the University of Virginia; the main house now holds the Thomas Jefferson Center for the Protection of Free Expression and the Kluge-Ruhe Aboriginal Art Collection.  The property was given its name by Jefferson: "pant-ops" are Greek words meaning "all seeing", alluding to the property's expansive views of the surrounding countryside. John Huger was the sixth intendent (mayor) of Charleston, South Carolina, serving two terms from 1792 to 1794.  He laid the cornerstone of the Charleston Orphan House, one of the city's most notable buildings, on November 12, 1792.  Before the Revolutionary War, he had been a member of the Commons House of Assembly and a member of the Council of Safety, the group that organized revolutionary movements in Charleston.  The location of Huger's estate, Hagan Plantation, was included in an almost 5,000 acre conservation easement. The Papers of Thomas Jefferson is a multi-volume scholarly edition devoted to the publication of the public and private papers of Thomas Jefferson, the third President of the United States.  The project, established at Princeton University, is the definitive edition of documents written by or to Jefferson.  Work on the series began in 1944 and was undertaken solely at Princeton until 1998, when responsibility for editing documents from Jefferson’s post-presidential retirement years, 1809 until 1826, shifted to the Thomas Jefferson Foundation at Monticello.  This enabled work to progress simultaneously on two different periods of Jefferson’s life and thereby doubled the production of volumes without compromising the high standards set for the project. The Thomas Jefferson Hour is a syndicated public radio program and podcast produced in Bismarck, North Dakota.  It features author-historian Clay S. Jenkinson in a first-person portrayal of Thomas Jefferson, the third US President, and is co-hosted by David Swenson.  Jenkinson remains in-character as Jefferson throughout the first half of the program, delivering monologues and answering listener questions regarding Jefferson's personal and political life and the history of early America.  The character of Jefferson generally confines his discussion to matters of history, politics, and philosophy as indirect context for modern times, but at times provides a limited analysis of current events (carefully attempting to limit his analysis to matters on which the actual Jefferson's view might be meaningfully determined).  In the second portion of the program, Jenkinson steps out of character to discuss his in-character answers during the first half of the show and also to talk generally about the topic of the episode. The Thomas Jefferson Foundation, originally known as the Thomas Jefferson Memorial Foundation, is a private, nonprofit 501(c)3 corporation founded in 1923 to purchase and maintain Monticello, the primary plantation of Thomas Jefferson, the third President of the United States.  The Foundation's initial focus was on architectural preservation, with the goal of restoring Monticello as close to its original appearance as possible.  It has since grown to include other historic and cultural pursuits and programs such as its Annual Independence Day Celebration and Naturalization Ceremony.  It also publishes and provides a center for scholarship on Jefferson and his era.
