Fleeing religious persecution and political turmoil in Britain, the Priestleys emigrated to the United States in 1794 seeking a peaceful life. Hoping to avoid the political troubles that had plagued them in Britain and the problems of urban life they saw in the United States, the Priestleys built a house in rural Pennsylvania. Nevertheless, political disputes and family troubles dogged Priestley during the last ten years of his life.

After the Priestleys died, their home remained in private hands until the turn of the 20th century, when George Gilbert Pond, a professor from what is now Pennsylvania State University

. According to J. D. Bowers, who studied Priestley's influence on Unitarianism in America, "[f]or a decade Priestley served as the inspiration and leading force in the spread of Unitarianism in America and the formation of numerous societies that followed his teachings on congregational formation, the education of youth, lay preaching, and espousing one's faith in the presence of opposition from (and to) both the Protestant majority and a competing liberal faction." Through Priestley's influence, at least 12 congregations were founded in Maine, Massachusetts, New York, Vermont, Pennsylvania, Virginia, and Kentucky, including the First Unitarian Church of Philadelphia

, which had better access to transportation and communication than Northumberland, but Mary preferred the country and wanted to be near her sons. Joseph considered splitting his time between Northumberland and Philadelphia, but this plan became impractical. Determined to ensure the future economic stability of his family, Priestley bought land and settled in Northumberland by July 1794, which was "five days of rough travel" north of Philadelphia. There they hoped a larger community would eventually blossom.

Settling in

Priestley seems to have yearned for a more cosmopolitan community than Northumberland provided, writing to his sister that it was "seemingly almost out of the world" and complaining that he had to wait a week for news. He wrote to his friend John Vaughan: "We know but little more than we did when we left you of European affairs." In the winter of 1794–95, Priestley wrote to friends that his situation was very "distant from my original views" and "my time here is far from passing so agreeably as it did in England", yet he was "very thankful for such an asylum" and he attempted "to make the best of my situation". In his letters to friends back in Britain, Priestley consistently referred to himself as an exile and to England as his real home. Mary was happier with the couple's situation and wrote to William Vaughan: "I am happy and thankful to meet with so sweet a situation and so peaceful a retreat as the place I now write from. Dr. Priestley also likes it and of his own choice intends to settle here, which is more than I hoped for at the time we came up...This country is very delightful, the prospects of wood and water more beautiful than I have ever seen before and the people plain and decent in their manners."

When the Priestleys' sons emigrated to America in 1793, they bought 300000 acres (1,214.1 km²) of land along Loyalsock Creek

 of the Susquehanna River). Shortly thereafter, Thomas Cooper, a friend of Joseph Priestley's, published a pamphlet in Britain titled Some Information Respecting America meant to encourage others to settle in Pennsylvania and offering instructions on how to do so. It detailed a clear plan for establishing and financing a settlement. The French translation, Renseignemens sur l'Amérique, was, according to one scholar, "carefully phrased in legal terminology" and "lucidly outline[d] an ambitious financial venture". However, it is unclear whether Cooper's scheme was related to the lands that the younger Priestleys had purchased.

n community which they called "Pantisocracy" (derived from the Greek for "equal rule of all"). They assembled 12 couples who were interested not only in demanding physical labor but also in a life of the mind, but none of them had enough money to embark on the project, which required much capital. Therefore the poets undertook a lecture tour of England to raise funds; however, they never generated enough money and never emigrated. The utopia was not built and few immigrants arrived in Northumberland as a result of Cooper's schemes.

After the failure of Cooper's endeavor, Priestley attempted to convince other friends to move to Northumberland, particularly those he had made in America, but to no avail. Priestley wrote in his Memoirs that "the settlement was given up, but being here, and my wife and myself liking the place, I have determined to take up my residence here, though subject to many disadvantages. Philadelphia was excessively expensive, and this a comparatively cheap place; and my sons, settling in the neighborhood, will be less exposed to temptation, and more likely to form habits of sobriety and industry."

. Cobbett published the letters in his newspaper, asserting that Priestley and his friends were fomenting a revolution. Priestley was eventually forced to defend himself in print.

Family matters also made Priestley's time in America difficult. His youngest son Harry died in December 1795, probably of malaria

The disease results from the multiplication of Plasmodium parasites within red blood cells, causing symptoms that typically include fever and headache, in severe cases...

. Mary Priestley died soon after in 1796; she was already ill and never fully recovered after the shock of her son's death. On September 14 of that year Joseph wrote: "This day I bury my wife....she had taken much thought in planning the new house and now that it is far advanced and promises to be everything she wished, she is removed to another." Priestley's family relations deteriorated even further in 1800 when a local Pennsylvania newspaper published an article accusing William Priestley, intoxicated with "French principles", of trying to poison the entire Priestley family—both father and son vigorously denied the story.
Priestley continued the educational projects that had been important to him throughout his life, helping to establish a "Northumberland Academy" and donating his library to the fledging institution. He exchanged letters regarding the proper structure of a university with Thomas Jefferson

Jefferson and Priestley became close and when he had completed his General History of the Christian Church, he dedicated it to President Jefferson, writing that "it is now only that I can say I see nothing to fear from the hand of power, the government under which I live being for the first time truly favourable to me."

(1772–74). However, he ended it by praising American religious toleration.

Priestley attempted to continue his scientific investigations in America with the support of the American Philosophical Association. However, he was hampered by lack of news from Europe; unaware of the latest scientific developments, Priestley was no longer on the forefront of discovery. Although the majority of his publications focused on defending the outmoded phlogiston theory

 and dreams. As Robert Schofield, Priestley's major modern biographer, explains:

Priestley published more scientific items during his decade in the United States than during all his years in England: some 45 papers, not counting reprintings, and four pamphlets, not counting subsequent editions, but in general his science was now anticlimactic. Few of his papers contributed anything significantly new to the field of chemistry; most were committed to combatting the new chemistry.

Despite Priestley's reduced scientific importance, he stimulated an interest in chemistry in America.

By 1801, Priestley had become so ill that he could no longer write or experiment effectively. On February 3, 1804, Joseph started a last experiment in his lab but was too weak to continue it. He went to a bed in his library, where he died three days later. He was buried in nearby Riverview Cemetery in Northumberland. Priestley's epitaph reads:
Return unto thy rest, O my soul, for the
Lord hath dealt bountifully with thee.
I will lay me down in peace and sleep till
I awake in the morning of the resurrection.

Architecture and landscaping

Joseph and Mary lived with their son Joseph, Jr. and his family in a small house while theirs was being built. Mary Priestley was primarily responsible for the design of the couple's new home and her family inheritance may have helped finance it, but she died before it was completed. By 1797, Joseph's laboratory was completed—the first part of the home to be finished. It was the first laboratory that "he had designed, built, and outfitted entirely himself" and was probably the first "scientifically-equipped laboratory" in the United States. Joseph continued his scientific and scholarly work in his new laboratory, identifying carbon monoxide

, calls it a "mansion" that is "probably the finest example of the Federal style in the region". As William N. Richardson, the site administrator for the Joseph Priestley House in the 1990s, notes, Priestley's American home did not resemble his "high-style Georgian town house" that was destroyed in Birmingham; rather, it was "plain" and built in the "American vernacular".

The house has a two-and-half story central section, which is 48 feet (14.6 m) by 43 feet (13.1 m), and two one-story wings on the north and south sides that are each 22 feet (6.7 m) by 21 feet (6.4 m). The first and second floors have a total area of 5,052 square feet (469 m²). The north wing was the laboratory and the south wing (which had an attached woodshed) was the summer kitchen. The cellar, first, and second floors of the central section are each divided into four rooms, with a central hall on the first and second floors; the first floor also has an intersecting hall that leads to the laboratory. The attic has three rooms for servants and a larger room for storage. A paint analysis done in 1994 revealed that the house had no wall paper initially and that the walls and woodwork were painted "a brilliant white".
The house is a frame structure, covered with white wooden clapboard

Originally, delightful panoramic views were visible from the home.

The lack of skilled craftspeople in Northumberland made the construction of the house difficult. For example, Richardson speculates that the main staircase was assembled from a kit. It is one step too short for the Northumberland hallway, but no extra step was added to finish off the symmetry of the stairwell, suggesting a dearth of skilled labor.

Ownership and museum

After the deaths of Mary and Joseph Priestley, Joseph Priestley, Jr. and his wife, Elizabeth Ryland, continued to live in the house until 1811, at which time they emigrated to Britain and sold the home. The house passed through various hands during the 19th century. Judge Seth Chapman purchased the house from Joseph Priestley Jr. on May 13, 1815 for US$6,250 ($  in ). Chapman died on December 4, 1835, and Rev. James Kay, pastor of the Northumberland Unitarian congregation, and his family lived in the house next. James Kay died on September 22, 1847 and his widow probably lived in the house until her October 2, 1850 death. Charles H. Kay, son of James, had purchased the house in 1845, a few years before his parents' deaths. In April 1865 Charles Kay's children sold the house to Henry R. Campbell for $2,775 ($  in ). Florence Bingham purchased the house from Campbell for $5,679.53 on January 18, 1868 ($  in ), and Bingham's heirs sold it to T. Hugh Johnson for $2,000 on October 7, 1882 ($  in ). Kate Scott bought the house for $3,000 on April 11, 1888 ($  in ). In 1911 the last private resident moved out of the house, and it was sublet to the Pennsylvania Railroad

 for its workers (a large railroad yard was built in Northumberland at this time). This led to a general decline in the house and its grounds.
Professor George Gilbert Pond was the first person to make a significant effort to establish a permanent Priestley museum at the Priestley House. After raising sufficient funds, he managed to purchase the home at auction for $6,000 from Scott's heirs on November 24, 1919 ($  in ). Pond believed that construction of a new railroad line would destroy the house, and so intended to move it to Pennsylvania State College (now Pennsylvania State University

). However, he died on May 20, 1920 before this plan could be enacted; the planned rail line was never built and the house proved too fragile to move. The college established a memorial fund in Pond's honor and retained the house as a museum, although Pond's children did not formally transfer the house to the college until April 14, 1932. Some restoration of the house was done in the 1920s, and a small, brick building—intended as a fireproof museum for Priestley's books and scientific apparatus—was built on the grounds and dedicated to Pond's memory in 1926.

 vetoed the plan for lack of funding.

On December 14, 1955, the college donated the house to the borough of Northumberland. From 1955 to 1959 the house served as both the borough hall for Northumberland and as a museum. The house proved too costly for the borough to maintain, and was acquired by the Commonwealth of Pennsylvania in 1961. Eventually, in 1968 the Pennsylvania Historical and Museum Commission

, a return of doorways to their original locations, and a return of the shutters "to their original locations inside the windows". The PHMC was supported by the "The Friends of the Joseph Priestley House" (FJPH), who help with the visitor center, tours, special events, and outreach, as well as with clerical and museum work.
Between 1998 and 1999 a renovation that was "one of the most extensive changes in the homestead's history" set out to "restore the grounds around the house to exactly the way it was when Priestley lived" there. This involved reconstructing exact replicas of the original carriage barn, hog sties, horse stalls, gardens, fences, and even the privy

. These structures were based on T. Lambourne's drawings of the house and grounds that had been discovered in 1983, other records, and excavations. Priestley left no written description of his laboratory, but much is known of his experiments and late-18th-century laboratories. Extensive research on the laboratory within the house was completed in 1996, including excavations that revealed two underground ovens, as well as evidence of a primitive fume hood

The house lost its original furnishings when Joseph Jr. and his family moved back to England. Since it is not known what was originally in the home, it is furnished and decorated with artifacts donated by descendants of the Priestleys and with ones similar to those listed in Priestley's testament of what was lost in the fire at his Birmingham home. A number of items that belonged to Joseph and Mary during their lives both in Britain and America are on display throughout the house, including Joseph's balance scales and microscope. Portraits, prints, maps, charts, and books have been carefully selected to replicate the Priestleys' holdings. A bedroom on the second floor is dedicated to an exploration of the life of an 18th-century woman.

Under the PHMC, the museum was open ten months a year, closing between early January and early March. In 2007 and 2008 the number of visitors held steady after recent declines. According to the PHMC, in fiscal 2007–08 "total visitation ... was 1,705 with a paid visitation of 1,100 generating $4,125 in program revenue and 2,406 recreational and non-ticketed visitors". The fiscal 2006–07 operations budget for the house and its two full-time staff was $142,901, with $6,900 (five percent) coming from FJPH and the rest from the state of Pennsylvania.
On March 4, 2009 the PHMC released a report examining its 22 museums and historic sites and recommended discontinuing operations at six, including the Joseph Priestley House. The proposed closure of the Priestley House was based on "low visitation and limited potential for growth". Despite public meetings, protest letters, and a general "public outcry" against closure, on August 14, 2009 the state closed the Priestley House and three other PHMC museums indefinitely due to a lack of funding as part of an ongoing budget crisis. The sole remaining state employee at Priestley House was furloughed. That month the Friends of the Joseph Priestley House submitted a plan to the PHMC to operate the house on weekends from May to October with staffing provided by volunteers. The plan depended both on acquiring insurance for the volunteers, the house, and its contents, and on the state passing a budget.

On September 24, 2009 the PHMC and officers of the FJPH signed an agreement to reopen the museum on Saturday and Sunday afternoons. The house reopened on October 3, with volunteer staffing from the FJPH. The agreement can be renewed annually and lets FJPH "schedule programs, set fees and be in charge of all the business aspects of running the site". On November 1, there was a "grand reopening celebration" at the house with a dozen costumed volunteer guides and chemical demonstrations in Priestley's laboratory. On November 7, 2010 the brick Pond building was rededicated after an $85,000 renovation, as part of the museum's annual "Fall Heritage Day". The restoration, which had been planned for years, was paid for by private donors and included "handicapped accessibility, new roofing, heating and air-conditioning and new interior walls, ceilings and lighting". The FJPH plan to install a timeline of Priestley's scientific work and times in the Pond building, as well as a video about his laboratory techniques and impact today.

American Chemical Society

The American Chemical Society (ACS) has used the Joseph Priestley House as a place to mark special celebrations. On July 31 and August 1, 1874, "seventy-seven chemists made a pilgrimage to the site to celebrate the centennial of chemistry". The date was chosen to mark the hundredth anniversary of Priestley's experiment producing oxygen by heating mercuric oxide with a magnifying lens and sunlight. These chemists came from 15 US states and the District of Columbia, Canada, and England, and their meeting at the house and a local school "is now recognized as the first National Chemistry Congress, and many ACS historians believe it led to ACS's formation two years later on April 6, 1876". On September 5, 1926, about 500 ACS members met again at the home to dedicate the small brick museum and to celebrate the meeting 50 years earlier (two survivors of that first meeting were present).

Representatives of the ACS were present at the October 1970 dedication of the house as a museum. On April 25, 1974 around 400 chemists from the ACS Middle Atlantic Regional Meeting in Scranton
