Pierre (Peter) Charles L'Enfant 1754-1825
Pierre (Peter) Charles was a French-born American architect and civil engineer best known for designing the layout of the streets of Washington, D.C.

Early Life

L'Enfant was born at Anet, Eure et Loir, the third child and second son of Marie Charlotte L'Enfant (aged 25 and the daughter of a minor marine official at court) and Pierre L'Enfant (1704-1787), a painter with a good reputation in the service of King Louis XV. In 1758, his brother Pierre Joseph died at the age of six, leaving him the eldest son. He studied at the Royal Academy in the Louvre before enrolling to fight in the American Revolution.

Military Service

L'Enfant was recruited by Pierre Augustin Caron de Beaumarchais to join in the American Revolutionary War in the American colonies. He arrived in 1777 at the age of 23, serving as a military engineer in the Continental Army with Major General Lafayette. Despite his aristocratic origins, L'Enfant closely identified with the United States, adopting the name Peter. He was wounded at the Siege of Savannah in 1779, but recovered and served in General George Washington's staff as a Captain of Engineers for the remainder of the Revolutionary War. During the war, L'Enfant was with George Washington at Valley Forge. While there, Marquis de Lafayette commissioned L'Enfant to paint a portrait of Washington. L'Enfant was promoted by brevet to Major of Engineers on May 2, 1783 in recognition of his service to American liberty. After the war, L'Enfant designed the badge of the Society of the Cincinnati, shaped as an eagle, at the request of Washington, and was sent to France to give the badges to French officers who fought in the war.

Architect and Planner
Post-Revolutionary War
Following the war, L'Enfant established a successful and highly profitable civil engineering firm in New York City. He achieved some fame as an architect by redesigning the City Hall in New York for the First Congress in Federal Hall. He also designed coins, medals, furniture and houses of the wealthy, and he was a friend of Alexander Hamilton. While L'Enfant was in New York City, he was initiated into Freemasonry. His initiation took place on April 17, 1789 at Holland Lodge No. 8 F&AM, which the Grand Lodge of New York F&AM had chartered in 1787. L'Enfant took only the first of three degrees offered by the lodge and did not progress further in Freemasonry. Plan for Federal Capital City

The new Constitution of the United States, which took effect in 1789, gave Congress authority to establish a federal district up to ten miles square in size. L'Enfant had already written to President Washington, asking to be commissioned to plan the city, but a decision on the capital was put on hold until July 1790 when the 1st Congress passed the Residence Act. The legislation, which was the result of a compromise brokered by Alexander Hamilton and Thomas Jefferson, specified the new capital be situated on the Potomac River, at some location between the Eastern Branch (the Anacostia River) and the Connogochegue, near Hagerstown, Maryland. The Residence Act gave authority to President Washington to appoint three commissioners to oversee the survey of the federal district and "according to such Plans, as the President shall approve," provide public buildings to accommodate the Federal government in 1800.

President George Washington appointed L'Enfant in 1791 to design the new capital city (later named the City of Washington) under the supervision of three Commissioners, whom Washington had appointed to oversee the planning and development of the federal territory that would later become the District of Columbia. Thomas Jefferson, who worked alongside President Washington in overseeing the plans for the capital, sent L'Enfant a letter outlining his task, which was to provide a drawing of suitable sites for the federal city and the public buildings. Though Jefferson had modest ideas for the Capital, L'Enfant saw the task as far more grandiose, believing he was not only locating the capital, but also devising the city plan and designing the buildings.

L'Enfant arrived in Georgetown on March 9, 1791, and began his work, from Suter's Fountain Inn. Washington arrived on March 28, to meet with L'Enfant and the Commissioners for several days. On June 22, L'Enfant presented his first plan for the federal city to President. On August 19, he appended a new map to a letter that he sent to the President.

President Washington retained one of L'Enfant's plans, showed it to Congress, and later gave it to the three Commissioners. The U.S. Library of Congress now holds both the plan that Washington apparently gave to the Commissioners and an undated anonymous survey map that the Library considers L'Enfant to have drawn before August 19, 1791. The survey map may be one that L'nfant appended to his August 19 letter to the President.

L'Enfant's "Plan of the city intended for the permanent seat of the government of the United States..." encompassed an area bounded by the Potomac River, the Eastern Branch, the base of the escarpment of the Atlantic Seaboard Fall Line, and Rock Creek. His plan specified locations for the "Congress house" (the Capitol), which would be built on Jenkins Hill, and the "President's house" (the White House), which would be situated on a ridge parallel to the Potomac River. L'Enfant envisioned the President's house to have public gardens and monumental architecture. Reflecting his grandiose visions, he specified that the President's house would be five times the size of the building that was actually constructed. Emphasizing the importance of the new nation's legislature, the Congress house would be located on a longitude designated as 0:0.

The plan specified that most streets would be laid out in a grid. To form the grid, some streets would travel in an east-west direction, while others would travel in a north-south direction. Diagonal avenues later named after the states of the union crossed the grid. The diagonal avenues intersected with the north-south and east-west streets at circles and rectangular plazas that would later honor notable Americans and provide open space.

L'Enfant laid out a 400 feet (122 m)-wide garden-lined "grand avenue", which he expected to travel for about 1 mile (1.6 km) along an east-west axis in the center of an area that would later become the National Mall. He also laid out a narrower avenue (Pennsylvania Avenue) which would connect the Congress house with the President's house. In time, Pennsylvania Avenue developed into the capital city's present "grand avenue".

Andrew Ellicott's 1792 revision of L'Enfant's plan for Washington, D.C.

L'Enfant's plan additionally laid out a system of canals (later designated as the Washington City Canal) that would pass the Congress house and the President's house. One branch of the canal would empty into the Potomac River south of the "President's house" at the mouth of Tiber Creek, which would be channelized and straightened.

L'Enfant secured the lease of quarries at Wigginton Island and along Aquia Creek in Virginia to supply stone for the foundation of the Congress house in November 1791. However, his temperament and his insistence that his city design be realized as a whole, brought him into conflict with the Commissioners, who wanted to direct the limited funds available into construction of the federal buildings. In this, they had the support of Thomas Jefferson.

During a contentious period in February 1792, Andrew Ellicott, who had been conducting the original boundary survey of the future District of Columbia...and the survey of the federal city under the direction of the Commissioners, informed the Commissioners that L'Enfant had not been able to have the city plan engraved and had refused to provide him with the original plan (of which L'Enfant had prepared several versions). Ellicott, with the aid of his brother, Benjamin Ellicott, then revised the plan, despite L'Enfant's protests. Shortly thereafter, Washington dismissed L'Enfant. After L'Enfant departed, Andrew Ellicott continued the city survey in accordance with the revised plan, several versions of which were engraved, published and distributed. As a result, Ellicott's revisions subsequently became the basis for the capital city's development.

L'Enfant was initially not paid for his work on his plan for the federal city. He fell into disgrace, spending much of the rest of his life trying to persuade Congress to pay him the tens of thousands of dollars that he claimed he was owed. After a number of years, Congress finally paid him a small sum, nearly all of which went to his creditors.

Later Works

After leaving the national capital area, L'Enfant prepared the initial plans for the city of Paterson, New Jersey, but was discharged from this project after a year had passed. During the same period (1792-1793) he designed Robert Morris' mansion in Philadelphia, which was never finished because of his delays and Morris' bankruptcy. In 1812, he was offered a position as a Professor of Engineering at United States Military Academy, but he declined that post. (He did serve as a Professor of Engineering at West Point from 1813 to 1817.) In 1814, L'Enfant worked briefly on the construction of Fort Washington on the Potomac River southeast of Washington, D.C., but others soon replaced him. L'Enfant surveyed and platted Perrysburg, Ohio on April 26, 1816. Washington, D.C., Indianapolis, IN and Perrysburg, Ohio are the cities that he designed.

NOTE: The following e-mail was sent to me correcting the above information:

"Good Morning, Deb...

A very nice Washington DC website!

Allow me to introduce myself...I am a local historian in Perrysburg, OH and have done extensive research on its history, and in particular, its surveys. One of the myths about Perrysburg (which you have on your website regarding Charles Pierre L'Enfant - ) is that he surveyed and platted this town in 1816.

This is not true. The site of the town was located by Alexander Bourne, assisted by Amos Spafford, and was surveyed and platted by US Government Deputy Surveyors Joseph Wampler and William Brookfield in August 1816 under the auspices of US Surveyor General Edward Tiffin.

The Ohio historical marker in Perrysburg stating 'The only two towns in the United States laid out by the federal government were Washington, DC and Perrysburg' is in error. This marker was made in 2008 before recent documented evidence surfaced showing at least ten (10) towns that were surveyed by the federal government.

The myth seems to have originated as a result of Perrysburg's two diagonal streets (Findlay, Sandusky) similar to those in Washington DC; however, they were not surveyed and platted until after 1835, more than 10 years after L'Enfant's death. Perrysburg also has East, West and South Boundary Streets similar to Washington DC's original Boundary Street (now Florida Avenue); however, these streets were not named until many years later, the first reference in print appearing in June 1848, 29 years after L'Enfant's death .

I have been searching the Internet, requesting website authors who have this incorrect history on their website to correct this error.

Death, Burial and Recognition

L'Enfant died in poverty. He was buried at the Green Hill farm in Chillum, Prince George's County, Maryland. He left behind three watches, three compasses, some books, some maps, and surveying instruments, whose total value was about forty-six dollars.

Grave of Pierre (Peter) Charles L'Enfant, overlooking the city he partially designed.

In 1901 and 1902, the McMillan Commission used L'Enfant's plan as the cornerstone of a report that recommended a partial redesign of the capital city. Among other things, the Commission's report laid out a plan for a sweeping mall in the area of L'Enfant's widest "grand avenue", which had not been constructed.

At the instigation of a French ambassador to the United States, Jean Jules Jusserand, L'Enfant's adopted nation then recognized his contributions. In 1909, after lying in state at the Capitol rotunda, L'Enfant's remains were re-interred in the Arlington National Cemetery in Virginia, on a hill overlooking the city that he had partially designed. In 1911, he was honored with a monument placed on top of his grave. Engraved on the monument is a portion of L'Enfant's own plan, which Andrew Ellicott's revision and the McMillan Commission's plan had superseded.


  • In 1942, a United States Liberty ship named the SS Pierre L'Enfant was launched. In 1970, she was shipwrecked and abandoned.
  • L'Enfant Plaza, a complex of office buildings, a hotel, and an underground shopping center centered around an esplanade (L'Enfant Promenade) in southwest Washington, D.C., was dedicated in 1968. Meeting rooms in the L'Enfant Plaza Hotel bear the names of French artists, military leaders, and explorers. The central portion of the plaza contains a map of the city. Within the city map is a smaller map that shows the plaza's location.
  • Beneath the L'Enfant Plaza is one of the central rapid transit Metro stops in Washington, D.C., the L'Enfant Plaza station.
  • In 1980, Western Plaza (subsequently renamed to Freedom Plaza) in northwest Washington, D.C., was designed. An inlay in the Plaza depicts parts of L'Enfant's plan for the City of Washington.
  • In 2003, L'Enfant's plan for Washington was commemorated on a USPS postage stamp. The diamond shape of the stamp reflects the original 100 square miles (259 km2) tract of land selected for the District. Shown is a view along the National Mall, including the Capitol, the Washington Monument, and the Lincoln Memorial. Also portrayed are cherry blossoms around the tidal basin and row houses from the Shaw neighborhood.
  • The Government of the District of Columbia has commissioned a statue of L'Enfant that it hopes will one day reside in the United States Capitol as part of the National Statuary Hall Collection. As federal law currently only allows U.S. states to contribute statues to the Collection, the District's delegate to the United States House of Representatives, Eleanor Holmes Norton, is attempting to have Congress change the law permit the installation of the statue in the Statuary Hall. The statue is presently displayed in a D.C. government office building.
  • Since 2005, the National Building Museum in Washington, D.C. has held an annual "L'Enfant Lecture on City Planning and Design" to draw attention to critical issues in city and regional planning in the United States.
