Andrew Ellicott (
January 24, 1754– August 28, 1820) was a U.S. surveyor who helped map many of the territories west of the Appalachians, surveyed the boundaries of the District of Columbia, continued and completed Peter (Pierre) Charles L'Enfant's work on the plan for Washington, D.C., and served as a teacher in survey methods for Meriwether Lewis.
Andrew Ellicott was born in
Buckingham Township, Bucks County, Pennsylvaniaas the first of nine children of Joseph Ellicott (1732 – 1780) and his wife Judith (née Blaker or Bleaker, 1729 – 1809).Williams, R.: " [http://archiver.rootsweb.com/th/read/QUAKER-ROOTS/1998-09/0906936665 Genealogy of Andrew Ellicott (1708 – 1741)] ", September 1998. Last accessed Aug 10, 2005.] Roberts, R.: " [http://worldconnect.rootsweb.com/cgi-bin/igm.cgi?op=GET&db=ralphroberts&id=I040719 Genealogy of Joseph Ellicott] ", 2001. Last accessed Aug 10, 2005.] The Quaker family lived in modest conditions; his father was a millerand clockmaker. Young Andrew was educated at the local Quaker school, where Robert Patterson, who later became a professor and vice provost at the University of Pennsylvania, was his teacher for some time. Andrew was a talented mechanic like many of the family and showed some mathematical talent, too.
In 1770, his father, together with his uncles Andrew (1733 – 1809) and John (1739 – 1794), purchased land on the
Patapsco Riverand set up a new milling business there, founding the town of Ellicott's Mills in 1772. Three years later, Andrew married Sarah Brown (1758 – 1827) of Newtown, Pennsylvania, with whom he would have ten children, one of which died as a child. When the Revolutionary War broke out, Andrew enlisted as a commissioned officer in the Elk Ridge Battalion of the Maryland militia despite his Quaker upbringing. During the course of the war, he rose to the rank of major, a title he would keep as an honorific throughout his life.
After the war, Ellicott returned home to Ellicott's Mills until he was appointed, in 1784, a member of the survey group tasked with extending the survey of the
Mason-Dixon linethat had been abandoned in 1767 and then been stalled during the war. In this survey, he worked alongside David Rittenhouseand James Madison, making first connections with the scientific society of Philadelphia.
Following the death of their second son, the Ellicotts moved to Baltimore in 1785, where Andrew taught mathematics at the Academy of Baltimore and was even elected to the legislature in 1786. The same year, he was called upon for a survey to define the western border of
Pennsylvania. This "Ellicott Line" (running north-south at 80°31'12"W United States Coast Guard: " [http://www.navcen.uscg.gov/mwv/regulations/33CFR003/33CFR3_45.htm#3.45-10 Coast Guard Organization: Ninth Coast Guard District: Buffalo Marine Inspection Zone] ", 2003.] ) later became the base line for the surveys of the Northwest Territory.N.N.: " [http://www.bchistory.org/beavercounty/BeaverCountyTopical/geologicalinformation/PublicLandSurveyMSA77/LandSurveyMSA77.html The Point of Beginning of the United States Public Land Survey] ", Milestones 3(4), 1977.] His work in Pennsylvania intensified his ties with Rittenhouse and other members of the American Philosophical Societyand led to encounters with Benjamin Franklinand Simeon De Witt. When he was subsequently appointed to lead other surveys in Pennsylvania, the family moved again in 1789 to Philadelphia. By recommendation of Franklin, Ellicott got a position with the newly established government and was tasked by George Washingtonto survey the lands between Lake Erieand Pennsylvania to determine the border between Western New Yorkand U.S. territory, resulting in the Erie Triangle. This survey, during which he also made the first topographical study of the Niagara Riverincluding the Niagara Falls, gained Ellicott a reputation for superb accuracy in surveys.
From 1791 to 1792, Ellicott worked under the direction of three commissioners that President
George Washingtonhad appointed, surveying the boundaries of the federal Territory of Columbia, which would become the District of Columbia in 1801. He was assisted in this survey first by the free African-American astronomer Benjamin Bannekerand then by Ellicott's brother, Joseph Ellicott. Ellicott's team put into place forty boundary stones (approximately one mile apart from each other) that marked the borders of the 100 square mile Territory of Columbia. Most of these stones remain in their original positions. As engravings on many of the stones still show, Ellicott's team placed those that marked the border with Virginia in 1791, and those that marked the border with Maryland in 1792.

During 1791-1792, Ellicott also surveyed the future city of Washington (located within a relatively small area at the center of the Territory of Columbia), first working with Peter (Pierre) Charles L' Enfant, who had prepared the initial plans for the capital city during the early months of 1791. After President
George Washingtondismissed L'Enfant in February1792, Ellicott was placed in charge of the planning and surveying of the capital city's streets. [Bowling, Kenneth R., Creating the federal city, 1774-1800 : Potomac fever. American Institute of Architects Press, Washington, D.C., 1988; [http://home.earthlink.net/~docktor/wmslogo.htm Plan of the City of Washington] "in" [http://home.earthlink.net/~docktor/washmap.htm Washington Map Society official website] . Accessed May 2, 2008.]
To L'Enfant's great dismay, Ellicott revised the original plan for the capital city by realigning and straightening Massachusetts Avenue, eliminating five short radial avenues and adding two others, removing several plazas and straightening the borders of the future
Judiciary Square. [ The U.S. National Archives holds a copy of "Ellicott's engraved Plan superimposed on the Plan of L'Enfant showing the changes made in the engraved Plan under the direction of President Washington". See "Scope & Contents" page of "Archival Description" for National Archives holding of "Miscellaneous Oversize Prints, Drawings and Posters of Projects Associated with the Commission of Fine Arts, compiled 1893 - 1950", ARC Identifier 518229/Local Identifier 66-M; Series from Record Group 66: Records of the Commission of Fine Arts, 1893 - 1981. Record of holding obtained through search in [http://arcweb.archives.gov/arc Archival Descriptions Search of ARC - Archival Research Catalog] using search term "L'Enfant Plan Ellicott", August 22, 2008.] Ellicott then sent his plan to James Thakara and John Valance of Philadelphia, who engraved, printed and published it. [ [http://home.earthlink.net/~docktor/wmslogo.htm Plan of the City of Washington] "in" [http://home.earthlink.net/~docktor/washmap.htm Washington Map Society official website] . Accessed May 2, 2008.] As Ellicott succeeded in having his plan engraved and published, the city's streets follow his plan, rather than that of L'Enfant. When he quit the City of Washington project, Ellicott was relieved to escape the political pressures surrounding that venture.
In 1794 Ellicott accepted a commission from Pennsylvania to plan the town of Erie. He spent the next two years with this task, plotting a road from
Reading, Pennsylvaniato Presqu'Isle, where the town was to be built, and supervising the construction of Fort Erie.
In 1796, George Washington commissioned Ellicott as the U.S. representative on the commission for the survey of the border between the Spanish territories in
Floridaand the United States negotiated in the Treaty of San Lorenzo. Ellicott travelled with a military escort via the Ohio and Mississippi rivers and worked together with Spanish commissioners, despite many difficulties, for the next four years. Another "Ellicott's Line" from this survey, running along 31°N, still defines the border between Alabamaand Florida.State of Alabama: " [http://www.legislature.state.al.us/CodeofAlabama/1975/41-2-3.htm Code of Alabama, sect. 41.2.3: Boundary between Alabama and Florida - Generally] ", 1975.] One of his markers for the boundary line survives to this day and bears his name, Ellicott's Stone. In 1798, he complained to the government about four American generals receiving pensions from Spain, including General James Wilkinson. Ellicott showed considerable diplomatic talent during this joint project to bring it to a successful completion, and he presented his final report with maps to the government in 1800.
The Adams administration, however, then refused to pay Ellicott for his work done in this survey, and even refused him access to his maps he had submitted with the report. He was forced to sell some of his possessions, including books from his library, in order to support his family. Finally the maps were released in 1803, and Ellicott published his "Journal of Andrew Ellicott" detailing the Florida survey, including the maps. When
Thomas Jeffersonoffered him the post of Surveyor General, Ellicott turned him down. His prior negative experiences with the administration may have had something to do with this, but at the age of 49, he also wanted to spend more time with his family and feared that this new position might require him to travel too much. Instead, he accepted an offer by Pennsylvania governor Thomas McKeanand took a position as Secretary of the Pennsylvania Land Office. The family moved to Lancaster, Pennsylvania, and Ellicott seemed content with a clerk's job that left him enough time for his own scientific and private interests and that provided a steady income for the family.
Also in 1803, Jefferson engaged Ellicott as a mentor and teacher for
Meriwether Lewis, one of the leaders of the Lewis and Clark Expeditionthat was to start the following year. From April to May 1803, Lewis stayed at Ellicott's home and studied survey techniques, and Ellicott made many recommendations on the expedition's equipment and survey procedures that were later followed. The two men apparently got along well.
Simon Snyderfollowed McKean as governor of Pennsylvania, he fired Elliott in 1809 due to political differences. A prominent supporter of Snyder was General James Wilkinson, one of the four generals that Ellicott had denounced eleven years earlier. Ellicott returned to private practice and was hired in February 1811 by David B. Mitchell, then governor of Georgia, to re-survey the border between Georgia and North Carolinato settle a border dispute between these two states. Although he started out in July, his expedition was delayed and had to work throughout the hard winter. Ellicott confirmed earlier findings that the border, which was supposed to follow 35°N, was several miles further south than the Georgians claimed. His report was not well received by the Georgian administration, who furthermore refused to pay his fees. Ellicott returned in July 1812 to Pennsylvania.
In 1813, Ellicott accepted a position as a professor for mathematics at the military academy at West Point, and the family left Lancaster and moved to
West Point, New York. In 1817, Ellicott was again called upon to participate as astronomer in a field survey to establish the western border between Canadaand the United States, which had been defined after the War of 1812in the Treaty of Ghentto run along 45°N. It was the last big survey that he performed. Ellicott died three years later from a strokein his home at West Point.
