Pierre "Peter" Charles L'Enfant (French: [pjɛʁ ʃɑʁl lɑ̃fɑ̃]; August 2, 1754 – June 14, 1825) was a French-American artist, professor, and military engineer. In 1791, L'Enfant designed the baroque-styled plan for the development of Washington, D.C., after it was designated to become the capital of the United States following its relocation from Philadelphia. His work, known as the L'Enfant Plan,^[1] inspired plans for other major world capitals, including Brasília, New Delhi, and Canberra. In the U.S., plans for the development of three major cities, Detroit, Indianapolis, and Sacramento, were inspired from from L'Enfant's plan for Washington, D.C.^[A] [3]

L'Enfant was born on August 2, 1754, in the Gobelins section of Paris, France, in the 13th arrondissement on the city's left bank.^[4] He was the third child and second son of Pierre L'Enfant (1704–1787), a painter and professor at Royal Academy of Painting and Sculpture known for his panoramas of battles,^[5] and Marie Charlotte Leullier, the daughter of a French military officer. In 1758, his brother Pierre Joseph died at six, and Pierre Charles became the eldest son.^[6] He studied with an intense curriculum at the Royal Academy from 1771 until 1776 with his father being one of his instructors. Academy classes were held at the Louvre, benefiting from the close proximity to some of Paris' greatest landmarks, such as the Tuileries Garden and Champs-Élysées, both designed by André Le Nôtre, and Place de la Concorde. L'Enfant would have also learned about city and urban planning during his time at the academy, likely examining baroque plans for Rome by Domenico Fontana and London by Sir Christopher Wren.

He was described by William Wilson Corcoran as "a tall, erect man, fully six feet in height, finely proportioned, nose prominent, of military bearing, courtly air and polite manners, his figure usually enveloped in a long overcoat and surmounted by a bell-crowned hat -- a man who would attract attention in any assembly."^[7] Sarah De Hart, daughter of New Jersey statesman John De Hart, drew a silhouette of L'Enfant in 1785, which now hangs in the Diplomatic Reception Rooms at the United States Department of State.

Boulevard Saint Marcel in Paris, where L'Enfant grew up

After his education L'Enfant was recruited by Pierre Augustin Caron de Beaumarchais to serve in the American Revolutionary War in the United States. He arrived in 1777 at the age of 23, and served as a military engineer in the Continental Army with Major General Lafayette.^[8] He was commissioned as a captain in the Corps of Engineers on April 3, 1779, to rank from February 18, 1778.^[9]

Despite his aristocratic origins, L'Enfant closely identified with the United States, changing his first name from Pierre to Peter when he first came to the rebelling colonies in 1777.^[10][11][12] L'Enfant served on General George Washington's staff at Valley Forge. While there, the Marquis de Lafayette commissioned L'Enfant to paint a portrait of Washington.^[13]

During the war, L'Enfant made a number of pencil portraits of George Washington and other Continental Army officers.^[14] He also made at least two paintings of Continental Army encampments in 1782.^[15] They depict panoramas of West Point and Washington's tent at Verplanck's Point. The latter details what is believed to be "the only known wartime depiction of Washington’s tent by an eyewitness."^[16] The seven-and-a-half-foot-long painting was purchased by the Museum of American Revolution in Philadelphia.

In the fall of 1779, L’Enfant contributed to the Regulations for the Order and Discipline of the Troops of the United States, authored by General Friedrich Wilhelm von Steuben. He was tasked to draft the eight "plates" or illustrations detailing camp and troop formations, as he was the only artistically trained individual involved. The "Blue Book" was completed by April 1779, receiving approval from General Washington and Congress. For his efforts, Congress awarded L’Enfant $500 and officially promoted him to captain of engineers, retroactive to February 1778.

L'Enfant was wounded at the Siege of Savannah on October 9, 1779. He recovered and became a prisoner of war at the surrender of Charleston, South Carolina, on May 12, 1780. He was exchanged in November 1780 and served on General Washington's staff for the remainder of the American Revolution. While the historical consensus generally attributes the creation of the Badge of Military Merit, later known as the Purple Heart, to George Washington in 1782, there is an implied claim by Pamela Scott, Washington D.C. historian and former editor of The L'Enfant Papers at the Library of Congress, that L'Enfant may have conceived the medal's design. L'Enfant was promoted by brevet to Major in the Corps of Engineers on May 2, 1783, in recognition of his service to the cause of American liberty. He was discharged when the Continental Army was disbanded in December 1783.^[17] In acknowledgment of his Revolutionary War contributions, L'Enfant received 300 acres of land in present-day Ohio from the United States. However, he never set foot on or resided in the granted land. A map outlining the territory was sketched on the reverse side of a segment of L'Enfant's land deed, signed by President Thomas Jefferson on January 13, 1803.^[18]

Alexander Hamilton, who supported L'Enfant and helped him secure work in Paterson, New Jersey after he was dismissed from the federal city project

Following the American Revolutionary War, L'Enfant settled in New York City and achieved fame as an architect by redesigning the City Hall in New York for the First Congress of the United States (See: Federal Hall).^[19]

L'Enfant also designed furniture and houses for the wealthy, as well as coins and medals. Among the medals was the eagle-shaped badge of the Society of the Cincinnati, an organization of former officers of the Continental Army of which he was a founder. At the request of George Washington, the first President of the Society, L'Enfant had the insignias made in France during a 1783–84 visit to his father and helped to organize a chapter of the Society there.^[20]

In 1787, L'Enfant received an inheritance upon his father's death that included a farm in Normandy^{[citation needed]}. His military pension and success as a designer provided financial stability enabling him to pursue his career and contribute to various projects for a period of time. 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 & A M, which the Grand Lodge of New York F & A M had chartered in 1787. L'Enfant took only the first of three degrees offered by the Lodge and did not progress further in Freemasonry.^[21]

L'Enfant designed the "Glory" ornamentation above the altar in St. Paul's Church. The chapel, built in 1766, is the oldest continuously used building in New York City. George Washington worshipped there on his inauguration day. The intricate design vividly depicts Mt. Sinai amidst clouds and lightning, capturing the dramatic moment of divine revelation. At the center of the piece is the Hebrew word for "God" enclosed within a triangle, symbolizing the Holy Trinity. Below, the two tablets of the Law are inscribed with the Ten Commandments, highlighting the enduring significance of these foundational moral laws.

L'Enfant was also a close friend of Alexander Hamilton. Some of their correspondences from 1793 to 1801 now reside in the Library of Congress.^[22] Hamilton is credited with helping L'Enfant with the federal city commission.
