The scene in 2019:

The Merchants’ Exchange Building is an important architectural landmark in Philadelphia, and it is also significant for having been the financial center of the city for many years. It was completed in 1834 as the first permanent home of what would become the Philadelphia Stock Exchange. Prior to this time, brokers and merchants met in a variety of coffee houses and taverns. However, by 1831 the city’s business leaders had recognized the need for a permanent, central location for a stock exchange, and began planning such a building.

The Exchange was designed by prominent Philadelphia architect William Strickland, who was heavily inspired by classical Greek architecture. The shape of the lot also contributed to the building’s design; although most of Philadelphia features a rectangular street grid, the Exchange was built on a triangular lot that was created by the diagonally-running Dock Street. As a result, the two main facades of the building are very different. Here at the west end of the building on Third Street, it has a fairly standard Greek Revival exterior, with Corinthian columns supporting a triangular pediment. However, on the east side of the building, facing Dock Street, Strickland designed an elaborate semi-circular columned facade that was topped by a tower. This tower, which is partially visible in the upper right corner of the 2019 photo, was inspired by the Choragic Monument of Lysicrates in Athens, which dates back to the fourth century B. C.

The cornerstone of the building was laid on February 22, 1832, on the one hundredth anniversary of George Washington’s birth. It was completed two years later, opening to the public in March 1834. A contemporary article in the Philadelphia Inquirer, republished from Bicknell’s Reporter, provides the following description:

It is built entirely of marble— occupies ninety-five feet front on Third street, and one hundred and fifty feet on Walnut. The basement story is fifteen feet high, and has twelve doorways on the Third Street front and flanks. The largest room in the lower floor, which is 74 by 36 feet, is occupied as the Philadelphia Post Office, at the west end of which is a hall or passage, designed for the shelter of persons while receiving or delivering letters. Beyond this hall to the west, and fronting Third street, is a large and commodious room, which has been fitted up as a Coffee Room, is now in the occupancy of Mr. J. Kerrison, a gentleman every way qualified to conduct a respectable establishment of the kind. South of the Post Office and the Coffee Room, is a large passage which runs from Dock to Third street, and further south again, a number of offices; which are to be occupied generally as Exchange and Insurance Offices. They open upon Walnut and Dock streets. No. 2 of this range will be occupied by the proprietor of this paper, as a Stock, Exchange and Publication Office.

Proceeding up stairs, the large Exchange Room, capable of containing several thousand persons, first arrests attention. It occupies an area of 83 superficial feet, fronts east, and extends across the whole building. The reading Room is oa [sic] the second floor, immediately over the Post Office, and is nearly of equal capacity. It is fitted up in the most appropriate manner, and is under the charge of Joseph M. Sanderson, Esq. assisted by Mr. J. Coffee. Both gentlemen are well know to our citizens, and are alike respected for urbanity of manner, intelligence, and attention to the duties entrusted to their care. Both have for several years been connected with the Merchants’ Coffee House of this city, Mr. Sanderson as Principal and Lessee of that establishment, and nothing can more fully show the estimation in which he is held by the Merchants than the fact of his unanimous election to the New Exchange.

The attic story is of the same height as the basement, 15 feet, contains six large rooms; the roof is of copper, and the ornaments on the semicircular portion over the front colonnade are very beautiful.

The building went on to serve as the city’s stock exchange for more than 40 years, in addition to housing other tenants such as the post office. However, in 1876 the stock exchange moved to the Girard Bank, located less than a hundred yards north of the Merchants’ Exchange on the opposite side of Third Street. This building was the home of the stock exchange until 1888, when it relocated to the Drexel Building a few blocks away. In a somewhat surprising move, though, the stock exchange then returned here to the Merchants’ Exchange at the turn of the 20th century, shortly after the first photo was taken. It remained here until 1913, when it moved into a new building at 1411 Walnut Street, near the corner of Market Street.

The Merchants’ Exchange Building was ultimately acquired by the National Park Service as part of the Independence National Historical Park. Although many other historic buildings within the park’s boundaries were demolished during this time, this building was preserved and restored, and it is now used as the park headquarters. It stands as the only surviving building in this scene from the first photo, and in 2001 it was designated as a National Historic Landmark because of its historical and architectural significance.

Independence Hall, Philadelphia, Pennsylvania (3)

The scene in 2019:

This view is similar to the one in a previous post, but this one shows the scene horizontally from a little further back, revealing more of the surrounding buildings near Independence Hall. As discussed in that post and another one, Independence Hall was the site of some of the country’s most important events in the years during and immediately after the American Revolution.

Independence Hall was completed in 1753 as the meeting place of the Pennsylvania colonial legislature, but at the start of the American Revolution it took on a second role as the de facto national capitol. The Second Continental Congress convened here on May 10, 1775, less than a month after the start of the war. The delegates met in the Assembly Room on the first floor of the building, which is located directly to the right of the tower in this scene. The building is most famous for the fact that the Declaration of Independence was voted on and signed here during the summer of 1776, but the building continued to be used by the Continental Congress throughout the Revolution, aside from two interruptions during British occupations of Philadelphia.

Congress finally left Philadelphia in June 1783, after a mob of about 400 soldiers descended upon the building, demanding payment for their wartime service. The state of Pennsylvania refused to deploy its militia to protect Congress, so the delegates left the city on June 21, and reconvened nine days later at Nassau Hall in Princeton, which became the first of several temporary national capitols over the next two years. Independence Hall would never again serve as the federal capitol building, but it nonetheless played another important role in 1787, when delegates from 12 of the 13 states met here for the Constitutional Convention. The result of this four-month convention was the current United States Constitution, which was signed here on September 17, 1787.

In the meantime, Independence Hall continued to serve as the seat of the state government. The federal government also returned to Philadelphia, although not to Independence Hall. Instead, two newer and smaller buildings were constructed, flanking Independence Hall. On the west side, barely visible on the extreme left side of the photos, is Congress Hall. This was the national capitol building from 1790 until 1800, with the House of Representatives occupying the large chamber on the first floor, and the Senate in a smaller chamber on the upper floor. On the opposite side of Independence Hall, on the extreme right side of the photos, is the Old City Hall. On the exterior, it is essentially identical to Congress Hall, and it was originally built to house the city government. However, during the 1790s it was also occupied by the Supreme Court, which had its courtroom on the ground floor.

The state government ultimately left Philadelphia in 1799 and moved to a more central location in Lancaster. Then, a year later, the federal government moved to Washington D.C., despite the best efforts by Philadelphians to retain the city’s status as the capital. No longer needed for governmental purposes, Independence Hall was threatened by demolition during the early 19th century. By this point the original wooden steeple was already gone, having been removed in 1781 and replaced by a low roof. Then, in 1812 the original wings on either side of Independence Hall were demolished, although the rest of the building was spared a similar fate after the city purchased it from the state in 1816.

It often takes many years before the significance of historic buildings is recognized, and in many cases this comes too late. For Independence Hall, though, it seems that its significance was widely understood by the 1820s. It was around this time that it came to be known as Independence Hall, rather than as the State House, and in 1825 the public square here in the foreground was formally named Independence Square. Three years later, a new steeple was constructed based on the plans of the original one, and it still stands atop the tower today.

By the time the first photo was taken around 1905, this scene had undergone further changes. Most significantly, the buildings that had replaced the old wings in 1812 were demolished in 1898, and new wings were constructed as replicas of the originals. Another change would come two years after the photo was taken, when the statue of Commodore John Barry was installed here in Independence Square, as shown in the 2019 photo.

Today, more than a century after the first photo was taken, Independence Hall still looks essentially the same. Both Congress Hall and the Old City Hall have also been preserved, and all three of these buildings are now part of the Independence National Historical Park. However, one notable difference in this scene from the first photo is the row of buildings beyond Independence Hall on the other side of Chestnut Street. All of these buildings, along with two more entire blocks further to the north, were demolished in the mid-20th century in an effort to improve the aesthetics of the area surrounding Independence Hall. However, in an example of historic buildings not being recognized until they are gone, the project included the removal of the remnants of the old President’s House, where George Washington and John Adams had lived during the 1790s. This site, at the corner of Sixth and Market Streets, is now marked by a partial reconstruction of some of the house’s architectural elements.

Congress Hall and Independence Hall, Philadelphia, Pennsylvania

The scene in 2019:

These two photos show the south side of Chestnut Street, between Sixth and Fifth Streets. This block contains three historic 18th century government buildings, each of which played an important role in the early history of the United States. In the center of this scene is Independence Hall, Philadelphia’s most famous historic landmark, which served as the meeting place of the Continental Congress and the Constitutional Convention. It is flanked on either side by two nearly identical buildings, both of which were occupied by the federal government in the late 18th century. In the foreground, to the west of Independence Hall, is Congress Hall, and to the east is the Old City Hall, which once housed the United States Supreme Court.

Independence Hall was completed in 1753, and it was originally used as the colonial capitol building of Pennsylvania. However, because of Philadelphia’s central location relative to the northern and southern colonies, it took on a second role during the American Revolution. Aside from several short interruptions during British occupations, the Continental Congress met here from 1775 until 1783, and it was during this time that the delegates approved and signed the Declaration of Independence in 1776. Congress left Philadelphia in 1783, but the building continued to be used by the state government. Then, during the summer of 1787, the Constitutional Convention met here to draft and sign the United States Constitution, which was ratified a year later.

At the time of the convention, New York City was the national capital, but in 1790 the federal government returned to Philadelphia, which would serve as the capital city for ten years while Washington D.C. was being developed. Rather than sharing Independence Hall with the state government, the federal government moved into its own buildings here. Congress Hall, shown in the foreground of these two photos, became the capitol building, with a chamber on the first floor for the House of Representatives, and a smaller one upstairs for the Senate. However, the building is noticeably smaller and more modest than the adjacent Independence Hall, providing an interesting visual contrast between the perceived importance of the state and federal governments during the nation’s early years.

Congress Hall was overshadowed by Independence Hall, both physically and also in terms of its historical significance. Nevertheless, a number of important events occurred here at Congress Hall. George Washington was inaugurated here at the start of his second term, as was John Adams four years later, and the Bill of Rights was formally added to the Constitution here in 1791. It was also here that Congress passed many important bills that would shape the future of the country, including legislation that established the First Bank of the United States, the Post Office, and the Navy.

On the far side of Independence Hall, at the corner of Fifth Street, is the Old City Hall. Its exterior is nearly identical to Congress Hall, and it was completed in 1791. It served as Philadelphia’s city hall until 1854, but it was also occupied by the United States Supreme Court from 1791 until 1800. The court held its sessions on the first floor during this period, with the city council meeting on the second floor. The first case in the history of the court, West v. Barnes, was argued here on August 2, 1791, and the court issued a unanimous decision the following day. Overall, though, the Supreme Court had a relatively minor role in the federal government in these early years, and the court decided few significant cases here in Philadelphia.

Both the state and federal governments left Philadelphia at the end of the 18th century, with the state capital moving to Lancaster in 1799 and the national capital to Washington a year later. Independence Hall faced threats of demolition in the early 19th century, and the building’s original wings were razed and replaced with new buildings, which are partially visible in the first photo. However, the main part of Independence Hall was ultimately preserved, and by the time the first photo was taken in the late 1850s it had become a major symbol of the American Revolution.

In the meantime, City Hall was occupied by the municipal government until 1854, and for many years Congress Hall served as the county courthouse. Both of these buildings were restored around the turn of the 20th century, and Congress Hall was rededicated in 1913 by President Woodrow Wilson. Around this same time, the 1812 wings of Independence Hall were replaced by replicas of the original wings. Since then, this scene has not changed very much in its appearance, and all three buildings are now part of the Independence National Historical Park, which was established in 1948.

Mount Pleasant, Philadelphia, Pennsylvania

The house in 2019:

Fairmount Park is located along the banks of the Schuylkill River, several miles to the northwest of downtown Philadelphia. During the colonial era, this area of the city was still sparsely-settled, and the bluffs overlooking the river were desirable locations for the country estates of some of Philadelphia’s affluent families. These mansions were generally used as summer homes, allowing these families to escape the heat and diseases of the densely-populated city center. Most of the homes were built in the 18th or early 19th centuries, and 16 are still standing today as part of Fairmount Park, the largest park in Philadelphia. Of these, perhaps the finest mansion is Mount Pleasant, which was built here in the early 1760s on the east bank of the Schuylkill River.

Mount Pleasant was designed by Thomas Nevell, and it is an excellent example of colonial Georgian-style architecture. As was typical for Georgian houses of the period, its design is symmetrical, and it makes use of decorative elements such as quoins on the corners, a pedimented doorway, a Palladian window, and a hip roof with dormers. The main house is flanked by two smaller buildings with matching exteriors. The one on the north side—which is just out of view on the right side of this scene—was the office, and the one on the south side, in the foreground of these photos, was the summer kitchen.

The original owner of this house was John MacPherson, a sea captain who became wealthy as a privateer during the French and Indian War. In command of the 20-gun ship Britannia, MacPherson captured several dozen French vessels throughout the war, in the process hurting the French war effort while simultaneously enriching himself. His exploits cost him his right arm, which he lost to a French cannonball in the midst of a battle, but upon returning to Philadelphia he used his new wealth to build his country estate here in Philadelphia. He originally named it Clunie, after his family’s ancestral home in Scotland, but subsequently changed it to Mount Pleasant. The size of the property also changed during MacPherson’s ownership; he started with about 31 acres, but the estate eventually grew to 120 acres.

MacPherson was a patriot during the American Revolution, and he even made an ultimately unsuccessful bid to become commander of the newly-established Continental Navy. His two sons, William and John, served in the Continental Army during the war. William resigned his commission as a British lieutenant in order to join the Continental Army, and he eventually became a brevet major and served on the staff of the Marquis de Lafayette. His brother John was also a staff officer during the war, serving as aide-de-camp to General Richard Montgomery, but both he and Montgomery were killed in the Battle of Quebec on December 31, 1775.

In the meantime, the elder John MacPherson interacted with high-ranking members of the Continental Congress, which met in Philadelphia’s Independence Hall throughout the war. On at least one occasion, on September 25, 1775, Massachusetts delegate John Adams visited him here at Mount Pleasant for dinner. The future president subsequently wrote about it in his diary, commenting on the house, his family, and MacPherson’s naval ambitions:

Rode out of town, and dined with Mr. McPherson. He has the most elegant seat in Pennsylvania, a clever Scotch wife, and two pretty daughters. His seat is on the banks of the Schuylkill. He has been nine times wounded in battle; an old sea commander; made a fortune by privateering; an arm twice shot off, shot through the leg, &c. He renews his proposals of taking or burning ships.

Despite living in “the most elegant seat in Pennsylvania,” MacPherson eventually decided to move out of the house and offer it for sale. He had no immediate buyers, but in the meantime he leased the house to Juan de Miralles, Spain’s unofficial envoy to the United States. Although Spain was officially neutral at this point in the war, Miralles established connections with many American leaders in Philadelphia, including by hosting lavish balls here at Mount Pleasant.

Then, in 1779 General Benedict Arnold purchased Mount Pleasant from John MacPherson. At the time, Arnold was still an ostensibly loyal officer in the Continental Army. He had been a hero at the Battle of Saratoga, but in the process he suffered a leg injury. During his recovery he was unable to fight on the front lines, so Washington appointed him military governor of Philadelphia in 1778. However, Arnold’s volatile personality made him ill-suited for a position that required tact and subtlety in dealing with local leaders, and he also faced accusations that he was using his position to enrich himself. It was also during his time in Philadelphia that Arnold met and fell in love with 18-year-old Peggy Shippen, whose wealthy family had Loyalist sympathies. Despite being twice her age and from a very different social background, Arnold began courting her later in 1778, and they were married on April 8, 1779.

At the time, Arnold’s financial situation was somewhat strained, and he was under suspicion for misusing his authority for personal gain. However, he purchased Mount Pleasant as a wedding gift for Peggy, giving the impression that he was wealthier than he really was. In reality, he was hampered by debt, which would only worsen after he and Peggy moved in here and began living a lavish lifestyle. This, combined with Arnold’s belief that patriot leaders were not grateful for his actions and sacrifices that he made on the battlefield, ultimately helped lead him to famously betray the Continental Army in 1780. Peggy likely played a role in this decision as well, as she had Loyalist connections and may have helped initiate contact between Arnold and his British handler, Major John André.

As it turned out, the Arnolds’ stay here at Mount Pleasant was short. His treason was discovered after André was captured on September 23, 1780, and Arnold himself only narrowly escaped capture. Mount Pleasant was subsequently confiscated, and it changed hands several times before being purchased by Peggy’s father, Edward Shippen, in 1784. Despite his Loyalist connections during the war, and the infamy of his son-in-law, Shippen remained a respected member of Philadelphia society, eventually becoming chief justice of the Supreme Court of Pennsylvania. He owned Mount Pleasant until 1792, when he sold it to Jonathan Williams.

Originally from Boston, Williams spent much of the Revolutionary period in France, first as a secretary to his great uncle, Benjamin Franklin, and then as a commercial agent of the United States. He later became an Army officer upon returning to the United States, and he held the position of Chief of Engineers for the Army Corps of Engineers from 1802 to 1803, and 1805 to 1812. During this time, he also became the first superintendent of West Point, serving from 1801 to 1803, and 1805 to 1812. In 1814 Williams was elected to the House of Representatives, but he died just two months into his term in 1815, without ever having attended a session of Congress.

After his death, his son Henry J. Williams inherited Mount Pleasant, and the house remained in the Williams family until 1853. By this point, the banks of the Schuylkill River were no longer as desirable a location for country estates as they had been a century earlier, in part because the city’s growth was encroaching on the area. Starting in the mid-19th century, the city of Philadelphia began purchasing estates along the river, in order to better protect the public water supply. These acquisitions became Fairmount Park, and in 1868 the city purchased Mount Pleasant and added it to the parkland.

The first photo was taken at the turn of the 20th century, and it shows the exterior in a somewhat deteriorated condition, with plenty of peeling paint on both the main house and the kitchen building. However, in 1927 Mount Pleasant was restored by the Philadelphia Museum of Art, which has administered the house ever since. It underwent another major restoration in the early 2000s, and today its exterior looks far better than it did when the first photo was taken 120 years ago. Adams’s description of it as being “the most elegant seat in Pennsylvania” is as true now as it was in 1775, and in 1974 it was designated as a National Historic Landmark because of its historic and architectural significance.

Maclean House, Princeton, New Jersey

The house in 2019:

As discussed in the previous post on Nassau Hall, Princeton University was established in 1746 in Elizabeth, New Jersey, as the College of New Jersey. The school moved to Newark a year later, and then to Princeton in 1756, upon completion of Nassau Hall. At the time, Nassau Hall encompassed all of the school’s amenities under one roof, including classrooms, dormitory rooms, offices, a dining room, and a meeting hall. However, the school did have a separate building for the college president, who lived here in this brick two-story house, located immediately to the northwest of Nassau Hall, fronting Nassau Street. Like its neighbor, the house was completed in 1756, and it was likewise designed by Philadelphia architect Robert Smith. Its first occupant was Aaron Burr Sr., who had served as Princeton’s president since 1748.

Burr died only a year after moving into this house, in the fall of 1757, leaving his widow Esther with two young children, including future vice president Aaron Burr, who was just a year and a half old at the time. Burr’s replacement as president was Esther’s father, Jonathan Edwards, the famous pastor and theologian. Edwards had begun his ministry career in Northampton, Massachusetts, where his preaching had helped to spark the Great Awakening. However, after many years in Northampton he was dismissed by the congregation in 1750, and he subsequently moved to the remote western Massachusetts town of Stockbridge. There, he served as a missionary to Native Americans until the College of New Jersey invited him to be its next president.

Edwards arrived here in Princeton in the midst of a smallpox epidemic, and one of his first priorities was to encourage students to receive a smallpox inoculation. Leading by example, he was inoculated on February 23, 1758. However, what was supposed to be just a mild case of smallpox progressively worsened over the next few weeks, and he died here at this house in Princeton on March 22, barely a month after becoming president of the college. He was buried in nearby Princeton Cemetery, alongside his predecessor and son-in-law, in a plot that later became known as Presidents’ Row because of the many college presidents interred there.

After Edwards’s death, this house was subsequently occupied by the next eight college presidents: Samuel Davies, Samuel Finley, John Witherspoon, Samuel Stanhope Smith, Ashbel Green, James Carnahan, John Maclean, and James McCosh. Of these, Witherspoon was probably the most notable. In addition to serving as president for more than 25 years, Witherspoon was also involved in politics during the Revolutionary War era. He was a delegate to the Continental Congress, and in that capacity he was one of the signers of the Declaration of Independence, becoming the only active clergyman to sign the document.

Aside from being the residence of many Princeton presidents, this house was also home to a number of slaves over the years. Most of the early presidents were slaveowners, and New Jersey was among the last of the northern states to abolish slavery. The state enacted a gradual emancipation plan starting in 1804, but slavery in New Jersey was not fully eliminated until the passage of the 13th Amendment in 1865. The last Princeton president to have slaves here in the house was Ashbel Green, who was president from 1812 to 1822. He had at least three slaves here during this time, including Betsey Stockton, whom he freed in 1817 when she was about 19 years old. She remained here as a paid servant for the next five years, and during this time she also received an education. Then, in 1822 she traveled to Hawaii as a Christian missionary, and upon returning to America she became an educator, eventually teaching for many years at an African-American school here in Princeton.

The last college president to occupy this house was James McCosh, who moved into the newly-acquired Prospect House in 1878. The house was then used as the residence of the dean of faculty, and seven different deans lived here between 1883 and 1967. The first photo was taken during this period, no later than 1894, and it shows the northern side of the house, from Nassau Street. This photo also shows two large sycamore trees standing in front of the house. These trees had been planted in 1765, less than a decade after the house was built, and by the time the photo was taken they were already nearly 130 years old.

Today, more than 125 years after the first photo was taken, very little has changed here in this scene. The house is now occupied by the Alumni Association of Princeton University, and it is named the Maclean House in honor of John Maclean, who lived here during his presidency and served as honorary president of the Alumni Association. Despite these changes in use, though, its exterior has remained well-preserved, and along with Nassau Hall it stands as the oldest building on the Princeton campus. Perhaps even more remarkable, though, is that the two sycamore trees are also still standing. Now more than 250 years old, they are nearly twice as old as they were in the first photo, and in the summer their leaves partially hide the view of the house from the street, as shown in the present-day photo.

Nassau Hall, Princeton, New Jersey

The building in 2019:

Nassau Hall, which opened in 1756, is the oldest building on the Princeton campus, and among the oldest college buildings in the United States. The College of New Jersey, as it was known at the time, was established in 1746, and it was originally located in Elizabeth before moving to Newark in 1747. Then, in 1753 Nathaniel FitzRandolph donated a plot of land here in Princeton to the school, and a year later the cornerstone was laid for this building. The building was nearly named for Governor Jonathan Belcher, but he demurred out of modesty, instead suggesting it be named Nassau Hall in honor of William III, who was from the House of Nassau.

Upon completion, Nassau Hall was one of the largest buildings in the English colonies, and the largest in New Jersey. It was the only building on campus at the time, so it was home to all of the school’s amenities, including a meeting hall, a dining room, offices, classrooms, and dormitory rooms. There were 70 students enrolled when the school moved here to Princeton, and its faculty consisted of the president, at the time Aaron Burr Sr., and two tutors. It was designed by Philadelphia architect Robert Smith, and one of the earliest descriptions of the building appeared in 1760 in the New American Magazine, which emphasized its rather spartan design:

There are three flat-arched doors on the north side giving access by a flight of steps to the three separate entries. At the center is a projecting section of five bays surmounted by a pediment with circular windows, and other decorations. The only ornamental feature above the cornice, is the cupola, standing somewhat higher than the twelve fireplace chimneys. Beyond these there are no features of distinction.

The simple interior design is shown in the plan, where a central corridor provided communication with the students’ chambers and recitation rooms, the entrances, and the common prayer hall; and on the second floor, with the library over the central north entrance. The prayer hall was two stories high, measured 32 by 40 feet, and had a balcony at the north end which could be reached from the second-story entry. Partially below ground level, though dimly lighted by windows, was the cellar, which served as kitchen, dining area (beneath the prayer hall), and storeroom. In all there were probably forty rooms for the students, not including those added later in the cellar when a moat was dug to allow additional light and air into that dungeon.

As was the case with most of the colonial-era colleges in the United States, the primary objective at the College of New Jersey was to prepare men to enter the ministry. However, while most were affiliated with either Puritanism or Anglicanism, this school was Presbyterian in its theology. Up until Woodrow Wilson in the early 20th century, all of its college presidents were ministers, and during the colonial era this included Great Awakening leader Jonathan Edwards and Declaration of Independence signer John Witherspoon.

Edwards arrived here in 1758, only two years after Nassau Hall was completed, but he died just a month later, after receiving a smallpox inoculation. The next two presidents also died relatively young, but John Witherspoon became president in 1768, and remained here until his death in 1794. During this time, he was also involved in politics, including serving on the Continental Congress, and he was the only clergyman among those who signed the Declaration of Independence.

Aside from these two presidents, the school also had a number of prominent students throughout the 18th century. Future president James Madison graduated from here in 1771, and one of his classmates was future vice president Aaron Burr, grandson of Jonathan Edwards, who graduated a year later. Others included Joseph Hewes, Benjamin Rush, and Richard Stockton, all of whom signed the Declaration of Independence along with Witherspoon.

After the end of the Revolution, ten Princetonians participated in the Constitutional Convention in Philadelphia, and five of them signed the Constitution: Gunning Bedford, David Brearley, Jonathan Dayton, James Madison, and William Paterson. Many other former Princeton students held other positions at the state and national level in the years during and immediately after the American Revolution. These included General Henry “Lighthorse Harry” Lee, who served as a cavalry officer in the Revolution and later as governor of Virginia, and Oliver Ellsworth, who served as the second Chief Justice of the United States.

However, it was not only Princeton’s students who played a role in the American Revolution; the school itself became a battleground during the Battle of Princeton on January 3, 1777. Prior to the battle, about 1,400 British soldiers were stationed in Princeton, and Nassau Hall was converted into barracks. During this time, the interior of the building was vandalized by the occupying army, and it was damaged even further during the battle itself. When Washington’s army advanced on Princeton, about 200 British soldiers took a defensive position inside of Nassau Hall, protected by the stone walls. However, the Continental Army opened fire on the building with cannons, and at least two cannonballs hit it before the British surrendered, effectively ending the battle.

Overall, the Battle of Princeton was a relatively small battle, but it helped to provide a much-needed morale boost for the Continental Army. Throughout the summer and fall of 1776, Washington had suffered a series of defeats as his army steadily retreated from New York City and across New Jersey. Thomas Paine famously described the situation as “the times that try men’s souls,” since many soldiers were deserting or not planning on re-enlisting after their enlistments expired on January 1, 1777. However, Washington’s surprise victory at Trenton on December 26, followed by Princeton a week later, helped to motivate soldiers to re-enlist and even inspired new recruits to join the army. Two years later, the Battle of Princeton was memorialized in Charles Willson Peale’s famous Washington at Princeton painting, depicting the commander in chief leaning against a cannon on the battlefield, with Nassau Hall visible in the distance on the left side of the painting.

Following the battle, Nassau Hall was occupied by the Continental Army throughout much of 1777, first as barracks and then as a hospital. This caused further damage to the interior, but at the end of the war the building took on a very different role when it temporarily became the capitol of the United States. Since 1775, Independence Hall in Philadelphia had been the meeting place of the Continental Congress. However, in 1783 a group of about 400 soldiers from the Continental Army marched on Independence Hall, demanding payment for their wartime service. Despite Congress’s requests, the Pennsylvania state government declined to use the militia to protect the building, so the Continental Congress left Philadelphia on June 21, and reconvened nine days later here at Princeton, in the second floor library of Nassau Hall.

Nassau Hall served as the capitol building for the next four months. During this time, on October 31, 1783, Congress was notified that British and American diplomats had signed the Treaty of Paris, ending the American Revolution. That same day, Congress also held a ceremony for diplomat Peter John van Berckel, who presented his credentials to Congress as the first Dutch ambassador to the United States. Van Berckel was apparently offended that his formal reception occurred in a small New Jersey town, rather than in Philadelphia as he had expected. However, he subsequently served as ambassador until 1788, and following the end of his term he continued to live in the United States for the rest of his life.

In any case, Congress did not remain in Princeton for much longer. It met here for the last time on November 4, 1783, and subsequently departed for Annapolis, where the Maryland State House functioned as the temporary national capitol. Congress would later return to the Princeton area, meeting in nearby Trenton for a little less than two months in late 1784 before moving to New York City in 1785. The capital city would then shift back to Philadelphia in 1790, before permanently moving to the newly-established city of Washington D.C. in 1800.

In the meantime, Nassau Hall continued to function as the home of the College of New Jersey throughout this time. However, on March 6, 1802 the building was completely gutted by a fire, leaving only the stone exterior walls still standing. The school soon began raising funds for its reconstruction, and among the donors were the citizens of Princeton, who feared that the school would use the opportunity to move out of the small town. For the work of rebuilding Nassau Hall, the school hired architect Benjamin Henry Latrobe, who is best known for having designed the United States Capitol in Washington. His plans for Nassau Hall were largely faithful to Robert Smith’s original design, and consisted of mostly minor stylistic changes. Perhaps the greatest difference was the roof, which was raised two feet higher than the original.

Thus restored, Nassau Hall would continue to be occupied by the school for the next half century, until another disastrous fire gutted it on March 10, 1855. This time, architect John Notman was responsible for the renovations, in the process making more drastic changes than Latrobe had. Inspired by Italianate-style architecture, which was popular at the time, Notman’s plans gave Nassau Hall more of a Renaissance appearance. Here on this side of the building, his design included a new arched doorway at the main entrance, and an arched window and balcony above it. Notman’s most significant alteration, though, was the addition of two Italianate towers, with one at each end of the building. The tower on the east side of the building is hidden behind the trees in the first photo, but the western tower is partially visible on the far right side of the scene.

The first photo was taken around 1903, and just two years later the tops of these towers were removed. Otherwise, though, the exterior of the building has not changed much since the 1855 reconstruction. However, the school’s use of Nassau Hall has evolved during this time. As Princeton added new buildings to its campus, Nassau Hall no longer needed to serve as an all-in-one building for dormitory rooms, classrooms, and offices. By 1924, the building was being used exclusively for administrative offices, including the offices of the university president, and it has been used for this purpose ever since.

Today, after surviving a Revolutionary War battle and two major fires, Nassau Hall still stands as an important part of the Princeton campus. It has been heavily altered, especially after the two fires, and the only original materials left in the building are the stone walls. Regardless, though, it remains one of the oldest college buildings in the country, and it is also important for its role in the Battle of Princeton and as the temporary capitol of the United States. Because of this, Nassau Hall was designated as a National Historic Landmark in 1960.
