Question: Who managed the 5,000 acre estate of Thomas Jefferson?

full_context: Document 1: Thomas Jefferson: Author of America: Thomas Jefferson: Author of America is a short biography of Thomas Jefferson, the third President of the United States (1801–09) and the principal author of the Declaration of Independence (1776), by author, journalist and literary critic Christopher Hitchens.
Document 2: Monticello: 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.
Document 3: Thomas Jefferson Foundation: 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.
Document 4: The Papers of Thomas Jefferson: 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.
Document 5: Monticello, New York: Monticello is a village located in Thompson in Sullivan County, New York, United States. The population was 6,726 at the 2010 census. It is the seat for the Town of Thompson and the county seat of Sullivan County. The village was named after the residence of Thomas Jefferson.
Document 6: Edmund Bacon (1785–1866): 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.
Document 7: Pantops Farm: 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.
Document 8: Walter Rathbone Bacon: Walter Rathbone Bacon (February 22nd, 1845 - November 14th, 1917) was an American capitalist who organised a system of tramways in Europe. Over his career, Bacon acted as director of Imperial Tramways Company, London Street Tramways Company, Corris Railway Company, Bell Punch Company Ltd., Hull Street Tramways Company, North Metropolitan Tramway Company and Belfast Street Tramways Company.
Document 9: Sally Hemings: Sarah "Sally" Hemings ( 1773 – 1835) was an enslaved woman of mixed race owned by President Thomas Jefferson. Most historians believe Jefferson was the father of her six children, born after the death of his wife, Martha Jefferson. Four survived to adulthood, and were given freedom by Jefferson. Hemings was the youngest of six siblings by the widowed planter John Wayles and a mixed-race woman he kept as a slave, Betty Hemings; Sally and her siblings were three-quarters European and half-siblings of Jefferson's wife, Martha Wayles Skelton. As an infant Sally came to Monticello as part of Martha's inheritance of her father's slave holdings.
Document 10: List of plantations in West Virginia: Plantations that operated within the present-day boundaries of West Virginia were located in the counties of the Ridge-and-Valley Appalachians and in the Kanawha and Ohio River valley regions. Beginning in the mid-to-late 18th century, members of the Washington family and other prominent Virginia families began to build elegant Georgian mansions on their plantations in the Ridge-and-Valley Appalachians region of present-day West Virginia. Plantations initially developed in the counties lying within the Northern Neck Proprietary of Thomas Fairfax, 6th Lord Fairfax of Cameron within the Shenandoah Valley and South Branch Potomac River valleys. Slavery as practiced through plantations in the American South was carried over from the plantations of the Piedmont and Tidewater regions of Virginia, where plantations had become the foundation of society and industry. Following the French and Indian War, settlement and agricultural development continued unabated in the Shenandoah and South Branch Potomac valleys. Early instances of western Virginia plantations with grand homes include the John Ariss-designed Harewood (1774) for George Washington's brother Samuel Washington and Happy Retreat (1780) built by Washington's younger brother Charles Washington, both of which are located near Charles Town in present-day Jefferson County. In Hampshire County, Nicholas Casey constructed a Georgian mansion (1774) at his Wappocomo plantation, one of the first plantation houses of its kind in the South Branch Potomac River valley.

Document 12: Bremo Historic District: Bremo, also known as Bremo Plantation or Bremo Historic District, is a plantation estate covering 1500 acres on the west side of Bremo Bluff in Fluvanna County, Virginia. The large mansion at Upper Bremo was designed by owner John Hartwell Cocke in consultation with John Neilson (c.1770 - 1827), the designer of Thomas Jefferson's Monticello. The estate includes two smaller residences built at Lower Bremo and Bremo Recess.
Document 13: Benjamin Banneker: Benjamin Banneker (November 9, 1731October 9, 1806) was a free African American almanac author, surveyor, naturalist, and farmer. Born in Baltimore County, Maryland, to a free African American woman and a former slave, Banneker had little formal education and was largely self-taught. He is known for being part of a group led by Major Andrew Ellicott that surveyed the borders of the original District of Columbia, the federal capital district of the United States.
Document 14: Jefferson's Manual: A Manual of Parliamentary Practice for the Use of the Senate of the United States, written by Thomas Jefferson in 1801, is the first American book on parliamentary procedure. As Vice President of the United States, Jefferson served as the Senate's presiding officer from 1797 to 1801. Throughout these four years, Jefferson worked on various texts and, in early 1800, started to assemble them into a single manuscript for the Senate's use. In December 1800 he delivered his manuscript to printer Samuel Harrison Smith, who delivered the final product to Jefferson on 27 February 1801.
Document 15: John Bacon (judge): Bacon is first mentioned as acting in the capacity of attorney to Queen Eleanor in 1278-9, and is described in certain indentures of the exchequer, dated 1288, as 'clericus Regis' and 'custos rotulorum et brevium de Banco' and 'Regis thesauriarius et camerarius,' his business being to keep a list of the cases argued in the common pleas, and to transmit records thereof, and also 'pedes chirographorum,' i.e. memoranda of fines levied throughout the country, to the treasurers and chamberlains of the exchequer, of the receipt of which the indentures already mentioned were acknowledgments. The 'chirographa,' or fines in question, were fictitious suits, by means of which it was the custom to bar entails and convey the landed property of married women. Bacon seems to have held this post as late as 1309. In 1291 he was entrusted with the charge of Leeds Castle in Kent (a royal residence). In 1313 he was appointed to a justiceship of the common pleas, and in the same year we read of his being retained in London to advise the king upon some important matters. In 1314 he was made one of the commissioners of oyer and terminer for the counties of Norfolk and Suffolk, to try certain assessors and collectors of the revenue charged with breach of trust. In 1315 William de Beresford, the chief justice of the common pleas, being suddenly summoned to the king, the business of the court devolved upon Thrikingham and Bacon exclusively. We may conjecture that it was not very promptly or efficiently despatched, for it was but a short time since he had been enjoined to pay a more diligent attention to duty. In 1317 he was summoned with the rest of the judges to parliament at Lincoln, but the invasion of the Scots in that year caused the postponement of the parliament sine die. In 1320 he was placed on a commission to try certain persons charged with debasing and counterfeiting the coinage in the counties of Essex, Norfolk, and Suffolk, and in 1321 upon another directed to inquire into offences committed by sheriffs and other legal functionaries under colour of their official duties in the counties of Norfolk, Suffolk, Cambridge, and Huntingdon. He appears to have died in this year, Stonore being appointed justice of the common pleas in his place. He had landed property in Reston, Hemingston, Cleydon, and Akenham, places all of them in the county of Suffolk, and also in Essex, and at Shouldham in Norfolk.
