Question: In what state did Isaac Jefferson work for Thomas Jefferson?
Context: 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. 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. Isaac Jefferson, also likely known as Isaac Granger (1775 - ca. 1850) was a valued, enslaved artisan of U.S. President Thomas Jefferson; he crafted and repaired products as a tinsmith, blacksmith, and nailer at Monticello. Thomas Jefferson University Hospitals Inc, branded as Jefferson Health, is a regional health system whose flagship hospital is Thomas Jefferson University Hospital in Center City, Philadelphia.

Other hospitals in the system include Jefferson Hospital for Neuroscience, Methodist Hospital in South Philadelphia, Abington Memorial Hospital in the northern suburb of Abington, the three hospitals and various clinics of Aria Health in Northeast Philadelphia and Lower Bucks County, and has signed a Definitive Agreement with Kennedy Health facilities in southern New Jersey including hospitals in Washington Township and Cherry Hill. This bibliography of Thomas Jefferson is a comprehensive list of written and published works about or by Thomas Jefferson, third President of the United States.  Up until 1851, virtually all biographical accounts for Jefferson relied on general and common knowledge gained from official records and public writings and newspapers.  It wasn't until Henry S. Randall, the first historian allowed to interview Jefferson's family, giving him access to family letters and records, did biographies of Jefferson take on a more intimate perspective.  Randall wrote a three volume biography which set the premise for many biographies that followed. 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 Jefferson–Hemings controversy is a historical debate over whether a sexual relationship between U.S. President Thomas Jefferson and his slave, Sally Hemings resulted in his fathering some or all of her six recorded children.  For more than 150 years, most historians denied rumors from Jefferson's presidency that he had a slave concubine.  Based on his grandson's report, they said that one of his nephews had been the father of Hemings' children.  Before changing his mind following the results of DNA analysis in 1998, Jefferson biographer Joseph J. Ellis had said, "The alleged liaison between Thomas Jefferson and Sally Hemings may be described as the longest-running miniseries in American history." 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. Thomas Jefferson is a bronze statue of Thomas Jefferson flanking the steps leading into the Cuyahoga County Courthouse in Cleveland, Ohio.  It is one of four statues Bitter created for the project, there was another bronze Alexander Hamilton and two marble attic figures, John Somers and Lord Mansfield.  Jefferson is portrayed wearing 18th Century clothes, sitting in a klismos chair holding “papers of state in hand.”  “It is a youthful and rebellious Jefferson, author of the Declaration of Independence who appears before us in Cleveland.”  This Jefferson is portrayed in a “generally rustic appearance” as opposed to the nearby Hamilton who is seen as an “aggressive young aristocrat.” 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.  Along with the Thomas Jefferson Foundation Medal in Law, the Thomas Jefferson Foundation Medal in Citizen Leadership, and the Thomas Jefferson Medal in Global Innovation, the awards are the highest external honors bestowed by the University, which grants no honorary degrees.
