[Wiseman, p. 31.]
Pei's ancestors' success meant that the family lived in the upper echelons of society, but Pei said his father was "not cultivated in the ways of the arts". The younger Pei, drawn more to music and other cultural forms than to his father's domain of banking, explored art on his own. "I have cultivated myself," he said later.
Pei studied in
St. Paul's College in Hong Kong as a child. When Pei was 10, his father received a promotion and relocated with his family to Shanghai. Pei attended St. John's Middle School, the secondary school of

The children were sent to live with extended family, as their father became more consumed by his work. Pei said: "My father began living his own separate life pretty soon after that." His father later married a woman named Aileen, who moved to New York later in her life.
Education and formative years
As Pei neared the end of his secondary education, he decided to attend university. He was accepted by a number of schools, but enrolled at the

. Pei's choice had two roots. While studying in Shanghai, he had closely examined the catalogs for various institutions of higher learning around the world. The architectural program at the University of Pennsylvania stood out to him. The other major factor was Hollywood. Pei was fascinated by the representations of college life in the films of
Bing Crosby

"Since I was too young to be serious, I wanted to be part of it ... You could get a feeling for it in Bing Crosby's movies. College life in America seemed very exciting to me. It's not real, we know that. Nevertheless, at that time it was very attractive to me." Pei added that "Crosby's films in particular had a tremendous influence on my choosing the United States instead of England to pursue my education."
In 1935, Pei boarded a boat and sailed to

Le Corbusier

[Boehm, p. 36; Wiseman, p. 36.]
Although he disliked the Beaux-Arts emphasis, Pei excelled in his studies. "I certainly don't regret the time at MIT", he said later. "There I learned the science and technique of building, which is just as essential to architecture."

BArch degree in 1940; his thesis was titled "Standardized Propaganda Units for War Time and Peace Time China".

In 1945, Eileen gave birth to a son, T'ing Chung, and she withdrew from the landscape architecture program in order to care for him.

Career
1948–1956: early career with Webb and Knapp
In the spring of 1948, Pei was recruited by New York real estate magnate
William Zeckendorf
William Zeckendorf Sr. (June 30, 1905 – September 30, 1976) was a prominent American real estate developer. Through his development company Webb and Knapp — for which he began working in 1938 and which he purchased in 1949 — he developed ...
to join a staff of architects for his firm of
Webb and Knapp to design buildings around the country. Pei found Zeckendorf's personality the opposite of his own; his new boss was known for his loud speech and gruff demeanor. Nevertheless, they became good friends and Pei found the experience personally enriching. Zeckendorf was well connected politically, and Pei enjoyed learning about the social world of New York's city planners.
His first project for Webb and Knapp was an apartment building, which received funding from the
Housing Act of 1949
The American Housing Act of 1949 () was a landmark, sweeping expansion of the federal role in mortgage insurance and issuance and the construction of public housing. It was part of President of the United States, President Harry Truman's program ...
. Pei's design was based on a circular tower with concentric rings. The areas closest to the supporting pillar handled utilities and circulation, and the apartments themselves were located toward the outer edge. Zeckendorf loved the design and even showed it off to Le Corbusier when they met. The cost of such an unusual design was too high, however, and the building never progressed beyond the model stage.
Pei finally saw his architecture come to life in 1949, when he designed a two-story
corporate building for Gulf Oil in

Katonah, New York in 1952. Soon, Pei was so inundated with projects that he asked Zeckendorf for assistants, which he chose from his associates at the GSD, including

Ulrich Franzen. They set to work on a variety of proposals, including the

. The first of these was the Mile High Center, which compressed the core building into less than 25 percent of the total site; the rest is adorned with an exhibition hall and fountain-dotted plazas. One block away, Pei's team also redesigned Denver's Courthouse Square, which combined office spaces, commercial venues, and hotels. These projects helped Pei conceptualize architecture as part of the larger urban geography: "I learned the process of development, and about the city as a living organism."
[Boehm, p. 52.] These lessons, he said, became essential for later projects.
Pei and his team also designed a united urban area for Washington, D.C., called

In 1955, Pei's group took a step toward institutional independence from Webb and Knapp by establishing a new firm called I. M. Pei & Associates. (The name changed later to I. M. Pei & Partners.) They gained the freedom to work with other companies, but continued working primarily with Zeckendorf. The new firm distinguished itself through the use of detailed

, Taiwan. The soaring structure, commissioned by the same organization that had run his middle school in Shanghai, broke severely from the cubist grid patterns of his urban projects.
The challenge of coordinating those projects took an artistic toll on Pei. He found himself responsible for acquiring new building contracts and supervising the plans for them. As a result, he felt disconnected from the actual creative work. "Design is something you have to put your hand to," he said. "While my people had the luxury of doing one job at a time, I had to keep track of the whole enterprise." Pei's dissatisfaction reached its peak at a time when financial problems began plaguing Zeckendorf's firm. I. M. Pei and Associates officially broke from Webb and Knapp in 1960, which benefited Pei creatively but pained him personally. He had developed a close friendship with Zeckendorf, and both men were sad to part ways.

The conceptualization stages were important for Pei, presenting a need and an opportunity to break from the Bauhaus tradition. He later recalled the long periods of time he spent in the area: "I recalled the places I had seen with my mother when I was a little boy—the mountaintop Buddhist retreats. There in the Colorado mountains, I tried to listen to the silence again—just as my mother had taught me. The investigation of the place became a kind of religious experience for me."

Roberts disliked Pei's initial designs, referring to them as "just a bunch of towers". Roberts intended his comments as typical of scientific experimentation, rather than artistic critique, but Pei was frustrated. His second attempt, however, fitted Roberts' vision perfectly: a spaced-out series of clustered buildings, joined by lower structures and complemented by two underground levels. The complex used many elements of

Once the laboratory was built, several problems with its construction became apparent. Leaks in the roof caused difficulties for researchers, and the shifting of clay soil beneath the building caused cracks which were expensive to repair. Still, both architect and project manager were pleased with the final result. Pei referred to the NCAR complex as his "breakout building", and he remained a friend of Roberts until the scientist died in .
The success of NCAR brought renewed attention to Pei's design acumen. He was recruited to work on a variety of projects, including the

in , his family and friends discussed constructing a library that would serve as a fitting memorial. A committee was formed to advise Kennedy's widow
Jacqueline, who would make the final decision. The group deliberated for months and considered many famous architects. Eventually, Kennedy chose Pei to design the library, based on two considerations. First, she appreciated the variety of ideas he had used for earlier projects. "He didn't seem to have just one way to solve a problem," she said. "He seemed to approach each commission thinking only of it and then develop a way to make something beautiful." Ultimately, however, Kennedy made her choice based on her personal connection with Pei. Calling it "really an emotional decision", she explained: "He was so full of promise, like Jack; they were born in the same year. I decided it would be fun to take a great leap with him."
The project was plagued with problems from the outset. President Kennedy had begun considering the structure of his library soon after taking office, and he wanted to include archives from his administration, a museum of personal items, and a political science institute. After the assassination, the list expanded to include a fitting memorial tribute to the slain president. The variety of necessary inclusions complicated the design process and caused significant delays.
Pei's first proposed design included a large glass pyramid that would fill the interior with sunlight, meant to represent the optimism and hope that Kennedy's administration had symbolized for so many in the United States. Mrs. Kennedy liked the design, but resistance began in

. By the mid-1970s, Pei tried proposing a new design, but the library's opponents resisted every effort. These events pained Pei, who had sent all three of his sons to Harvard, and although he rarely discussed his frustration, it was evident to his wife. "I could tell how tired he was by the way he opened the door at the end of the day," she said. "His footsteps were dragging. It was very hard for I. M. to see that so many people didn't want the building."

. The new site was less than ideal; it was located on an old landfill, and just over a large sewage pipe. Pei's architectural team added more fill to cover the pipe and developed an elaborate ventilation system to conquer the odor. A new design was unveiled, combining a large square glass-enclosed atrium with a triangular tower and a circular walkway.
The
John F. Kennedy Presidential Library and Museum was dedicated on October 20, 1979. Critics generally liked the finished building, but the architect himself was unsatisfied. The years of conflict and compromise had changed the nature of the design, and Pei felt that the final result lacked its original passion. "I wanted to give something very special to the memory of President Kennedy," he said in 2000. "It could and should have been a great project."
Pei's work on the Kennedy project boosted his reputation as an architect of note.

, Oklahoma, in 1964. The plan called for the demolition of hundreds of old downtown structures in favor of renewed parking, office building, and retail developments, in addition to public projects such as the Myriad Convention Center and the Myriad Botanical Gardens. It was the dominant template for downtown development in Oklahoma City from its inception through the 1970s. The plan generated mixed results and opinion, largely succeeding in re-developing office building and parking infrastructure but failing to attract its anticipated retail and residential development. Significant public resentment also developed as a result of the destruction of multiple historic structures. As a result, Oklahoma City's leadership avoided large-scale urban planning for downtown throughout the 1980s and early 1990s, until the passage of the
Metropolitan Area Projects (MAPS) initiative in 1993.

mirrored those of other projects; he surveyed the surrounding area and worked to make the building fit. In the case of Dallas, he spent days meeting with residents of the city and was impressed by their civic pride. He also found that the skyscrapers of the downtown business district dominated the skyline, and sought to create a building which could face the tall buildings and represent the importance of the public sector. He spoke of creating "a public-private dialogue with the commercial high-rises".
Working with his associate Theodore Musho, Pei developed a design centered on a building with a top much wider than the bottom; the facade leans at an angle of 34 degrees, which shades the building from the Texas sun. A plaza stretches out before the building, and a series of support columns holds it up. It was influenced by Le Corbusier's
High Court building in Chandigarh, India; Pei sought to use the significant overhang to unify the building and plaza. The project cost much more than initially expected, and took 11 years to complete. Revenue was secured in part by including a subterranean parking garage. The interior of the city hall is large and spacious; windows in the ceiling above the eighth floor fill the main space with light.
The city of Dallas received the building well, and a local television news crew found unanimous approval of the new city hall when it officially opened to the public in 1978. Pei himself considered the project a success, even as he worried about the arrangement of its elements. He said: "It's perhaps stronger than I would have liked; it's got more strength than finesse."
[Quoted in Wiseman, p. 136.] He felt that his relative lack of experience left him without the necessary design tools to refine his vision, but the community liked the city hall enough to invite him back. Over the years he went on to design five additional buildings in the Dallas area.
Hancock Tower, Boston

While Pei and Musho were coordinating the Dallas project, their associate
Henry Cobb had taken the helm for a commission in Boston.
John Hancock Insurance chairman Robert Slater hired I. M. Pei & Partners to design a building that could overshadow the

After the firm's first plan was discarded due to a need for more office space, Cobb developed a new plan around a towering parallelogram, slanted away from the
Trinity Church and accented by a wedge cut into each narrow side. To minimize the visual impact, the building was covered in large reflective glass panels; Cobb said this would make the building a "background and foil" to the older structures around it. When the
Hancock Tower was finished in 1976, it was the tallest building in

.

Serious issues of execution became evident in the tower almost immediately. Many glass panels fractured in a windstorm during construction in 1973. Some detached and fell to the ground, causing no injuries but sparking concern among Boston residents. The entire tower was reglazed with smaller panels, significantly increasing costs. Hancock sued the glass manufacturers, Libbey-Owens-Ford, as well as I. M. Pei & Partners, for submitting plans that were "not good and workmanlike". LOF countersued Hancock for defamation, accusing Pei's firm of poor use of their materials; I. M. Pei & Partners sued LOF in return. All three companies settled out of court in 1981.

s. Inspiration struck Pei in 1968, when he scrawled a rough diagram of two triangles on a scrap of paper. The larger building would be the public gallery; the smaller would house offices and archives. This triangular shape became a singular vision for the architect. As the date for groundbreaking approached, Pedersen suggested to his boss that a slightly different approach would make construction easier. Pei simply smiled and said: "No compromises."
The growing popularity of art museums presented unique challenges to the architecture. Mellon and Pei both expected large crowds of people to visit the new building, and they planned accordingly. To this end, Pei designed a large lobby roofed with enormous skylights. Individual galleries are located along the periphery, allowing visitors to return after viewing each exhibit to the spacious main room. A large

The East Building was honored on May 30, 1978, two days before its public unveiling, with a black-tie party attended by celebrities, politicians, benefactors, and artists. When the building opened, popular opinion was enthusiastic. Large crowds visited the new museum, and critics generally voiced their approval.

in 1974, which Pei joined. It was his first trip back to China since leaving in 1935. He was favorably received, returned the welcome with positive comments, and a series of lectures ensued. Pei noted in one lecture that since the 1950s Chinese architects had been content to imitate Western styles; he urged his audience in one lecture to search China's native traditions for inspiration.

In 1978, Pei was asked to initiate a project for his home country. After surveying a number of different locations, Pei fell in love with a valley that had once served as an imperial garden and hunting preserve known as
Fragrant Hills. The site housed a decrepit hotel; Pei was invited to tear it down and build a new one. As usual, he approached the project by carefully considering the context and purpose. Likewise, he considered modernist styles inappropriate for the setting. Thus, he said, it was necessary to find "a third way".
After visiting his ancestral home in Suzhou, Pei created a design based on some simple but nuanced techniques he admired in traditional residential Chinese buildings. Among these were abundant gardens, integration with nature, and consideration of the relationship between enclosure and opening. Pei's design included a large central atrium covered by glass panels that functioned much like the large central space in his East Building of the National Gallery. Openings of various shapes in walls invited guests to view the natural scenery beyond. Younger Chinese who had hoped the building would exhibit some of Cubist flavor for which Pei had become known were disappointed, but the new hotel found more favor with government officials and architects.
The hotel, with 325 guest rooms and a four-story central atrium, was designed to fit perfectly into its natural habitat. The trees in the area were of special concern, and particular care was taken to cut down as few as possible. He worked with an expert from Suzhou to preserve and renovate a water maze from the original hotel, one of only five in the country. Pei was also meticulous about the arrangement of items in the garden behind the hotel; he even insisted on transporting of rocks from a location in southwest China to suit the natural aesthetic. An associate of Pei's said later that he never saw the architect so involved in a project.
During construction, a series of mistakes collided with the nation's lack of technology to strain relations between architects and builders. Whereas 200 or so workers might have been used for a similar building in the US, the Fragrant Hill project employed over 3,000 workers. This was mostly because the construction company lacked the sophisticated machines used elsewhere. The problems continued for months, until Pei had an uncharacteristically emotional moment during a meeting with Chinese officials. He later explained that his actions included "shouting and pounding the table" in frustration. The design staff noticed a difference in the manner of work among the crew after the meeting. As the opening neared, however, Pei found the hotel still needed work. He began scrubbing floors with his wife and ordered his children to make beds and vacuum floors. The project's difficulties took an emotional and physical strain on the Pei family.
The Fragrant Hill Hotel opened on October 17, 1982, but quickly fell into disrepair. A member of Pei's staff returned for a visit several years later and confirmed the dilapidated condition of the hotel. He and Pei attributed this to the country's general unfamiliarity with deluxe buildings. The Chinese architectural community at the time gave the structure little attention, as their interest at the time centered on the work of American

of interconnected metal rods and spheres.
The convention center was plagued from the start by budget problems and construction blunders. City regulations forbid a general contractor having final authority over the project, so architects and program manager Richard Kahan had to coordinate the wide array of builders, plumbers, electricians, and other workers. The forged steel globes to be used in the space frame came to the site with hairline cracks and other defects: 12,000 were rejected. These and other problems led to media comparisons with the disastrous Hancock Tower. One New York City official blamed Kahan for the difficulties, indicating that the building's architectural flourishes were responsible for delays and financial crises. The Javits Center opened on April 3, 1986, to a generally positive reception.

. Mitterrand appointed a civil servant named to oversee it. After visiting museums in Europe and the United States, including the U.S. National Gallery, he asked Pei to join the team. The architect made three secretive trips to Paris, to determine the feasibility of the project; only one museum employee knew why he was there. Pei finally agreed that a new construction project was not only possible, but necessary for the future of the museum. He thus became the first foreign architect to work on the Louvre.
The heart of the new design included not only a renovation of the
Cour Napoléon in the midst of the buildings, but also a transformation of the interiors. Pei proposed a central entrance, not unlike the lobby of the National Gallery East Building, which would link the three major wings around the central space. Below would be a complex of additional floors for research, storage, and maintenance purposes. At the center of the courtyard he designed a
glass and steel pyramid, first proposed with the Kennedy Library, to serve as entrance and anteroom skylight. It was mirrored by an
inverted pyramid to the west, to reflect sunlight into the complex. These designs were partly an homage to the fastidious geometry of the French landscape architect
André Le Nôtre
André Le Nôtre (; 12 March 1613 – 15 September 1700), originally rendered as André Le Nostre, was a French landscape architect and the principal gardener of King Louis XIV of France. He was the landscape architect who designed Gardens ...
. Pei also found the pyramid shape best suited for stable transparency, and considered it "most compatible with the architecture of the Louvre, especially with the faceted planes of its roofs".
Biasini and Mitterrand liked the plans, but the scope of the renovation displeased Louvre administrator André Chabaud. He resigned from his post, complaining that the project was "unfeasible" and posed "architectural risks". Some sections of the French public also reacted harshly to the design, mostly because of the proposed pyramid. One critic called it a "gigantic, ruinous gadget";
[Quoted in Wiseman, p. 249.] another charged Mitterrand with "despotism" for inflicting Paris with the "atrocity".
Pei estimated that 90 percent of Parisians opposed his design. "I received many angry glances in the streets of Paris," he said. Some condemnations carried
nationalistic overtones. One opponent wrote: "I am surprised that one would go looking for a Chinese architect in America to deal with the historic heart of the capital of France."

Soon, however, Pei and his team won the support of several key cultural icons, including the conductor

and placed a full-sized cable model of the pyramid in the courtyard. During the four days of its exhibition, an estimated 60,000 people visited the site. Some critics eased their opposition after witnessing the proposed scale of the pyramid.
Pei demanded a method of glass production that resulted in clear panes. The pyramid was constructed at the same time as the subterranean levels below, which caused difficulties during the building stages. As they worked, construction teams came upon an abandoned set of rooms containing 25,000 historical items; these were incorporated into the rest of the structure to add a new exhibition zone.
The new

The opening of the Louvre Pyramid coincided with four other projects on which Pei had been working, prompting architecture critic

At the age of 72, Pei had begun thinking about retirement, but continued working long hours to see his designs come to light.

One of the projects took Pei back to Dallas, Texas, to design the

Eduardo Mata, led to interest by city leaders in creating a modern center for musical arts that could rival the best halls in Europe. The organizing committee contacted 45 architects, but at first Pei did not respond, thinking that his work on the Dallas City Hall had left a negative impression. One of his colleagues from that project, however, insisted that he meet with the committee. He did and, although it would be his first concert hall, the committee voted unanimously to offer him the commission. As one member put it: "We were convinced that we would get the world's greatest architect putting his best foot forward."
Because its main purpose was the presentation of live music, the hall needed a design focused on

. The project was risky: its goals were ambitious and any unforeseen acoustic flaws would be virtually impossible to remedy after the hall's completion. Pei admitted that he did not completely know how everything would come together. "I can imagine only 60 percent of the space in this building," he said during the early stages. "The rest will be as surprising to me as to everyone else." As the project developed, costs rose steadily and some sponsors considered withdrawing their support. Billionaire tycoon

After attending a week of performances in the hall, a music critic for ''The New York Times'' wrote an enthusiastic account of the experience and congratulated the architects. One of Pei's associates told him during a party before the opening that the symphony hall was "a very mature building"; he smiled and replied: "Ah, but did I have to wait this long?"

A new offer had arrived for Pei from the Chinese government in 1982. With an eye toward the

The handover of Hong Kong from the United Kingdom to the People's Republic of China was at midnight on 1 July 1997. This event ended 156 years of British rule in the former colony, which began in 1841.

. The Chinese government was preparing for a new wave of engagement with the outside world and sought a tower to represent modernity and economic strength. Given the elder Pei's history with the bank before the Communist takeover, government officials visited the 89-year-old man in New York to gain approval for his son's involvement. Pei then spoke with his father at length about the proposal. Although the architect remained pained by his experience with Fragrant Hills, he agreed to accept the commission.
The proposed site in Hong Kong's
Central District was less than ideal; a tangle of highways lined it on three sides. The area had also been home to a headquarters for Japanese military police during World War II, and was notorious for prisoner torture. The small parcel of land made a tall tower necessary, and Pei had usually shied away from such projects; in Hong Kong especially, the skyscrapers lacked any real architectural character. Lacking inspiration and unsure of how to approach the building, Pei took a weekend vacation to the family home in
Katonah, New York. There he found himself experimenting with a bundle of sticks until he happened upon a cascading sequence.
Pei felt that his design for the
Bank of China Tower needed to reflect "the aspirations of the Chinese people". The design that he developed for the skyscraper was not only unique in appearance, but also sound enough to pass the city's rigorous standards for wind-resistance. The building is composed of four triangular shafts rising up from a square base, supported by a visible

structure that distributes stress to the four corners of the base. Using the reflective glass that had become something of a trademark for him, Pei organized the facade around diagonal bracing in a union of structure and form that reiterates the triangle motif established in the plan. At the top, he designed the roofs at sloping angles to match the rising aesthetic of the building. Some influential advocates of ''

As the tower neared completion, Pei was shocked to witness the government's massacre of unarmed civilians at the

[Quoted in Wiseman, p. 294.] The massacre deeply disturbed his entire family, and he wrote that "China is besmirched."
1990–2019: museum projects
As the 1990s began, Pei transitioned into a role of decreased involvement with his firm. The staff had begun to shrink, and Pei wanted to dedicate himself to smaller projects allowing for more creativity. Before he made this change, however, he set to work on his last major project as active partner: the

. The sponsors of the hall, however, sought Pei for specifically this reason; they wanted the building to have an aura of respectability from the beginning. Pei accepted the commission in part because of the unique challenge it presented.
Using a glass wall for the entrance, similar in appearance to his Louvre pyramid, Pei coated the exterior of the main building in white metal, and placed a large cylinder on a narrow perch to serve as a performance space. The combination of off-centered wraparounds and angled walls was, Pei said, designed to provide "a sense of tumultuous youthful energy, rebelling, flailing about".
The building opened in 1995, and was received with moderate praise. ''The New York Times'' called it "a fine building", but Pei was among those who felt disappointed with the results. The museum's early beginnings in New York combined with an unclear mission created a fuzzy understanding among project leaders for precisely what was needed.
[Quoted in Wiseman, p. 307.] Although the city of Cleveland benefited greatly from the new tourist attraction, Pei was unhappy with it.
At the same time, Pei designed a new museum for

, the ''Musée d'art moderne Grand-Duc Jean'', commonly known as the

Fort Thüngen walls where the museum was located, Pei planned to remove a portion of the original foundation. Public resistance to the historical loss forced a revision of his plan, however, and the project was nearly abandoned. The size of the building was halved, and it was set back from the original wall segments to preserve the foundation. Pei was disappointed with the alterations, but remained involved in the building process even during construction.
In 1995, Pei was hired to design an extension to the ''

approach with a classical main structure. He described the glass cylinder addition as a "beacon", and topped it with a glass roof to allow plentiful sunlight inside. Pei had difficulty working with German government officials on the project; their utilitarian approach clashed with his passion for aesthetics. "They thought I was nothing but trouble", he said.
Pei also worked at this time on two projects for a
new Japanese religious movement called ''
Shinji Shumeikai''. He was approached by the movement's spiritual leader, Kaishu Koyama, who impressed the architect with her sincerity and willingness to give him significant artistic freedom. One of the buildings was a bell tower, designed to resemble the ''
bachi'' used when playing traditional instruments like the ''

''. Pei was unfamiliar with the movement's beliefs, but explored them in order to represent something meaningful in the tower. As he said: "It was a search for the sort of expression that is not at all technical."

The experience was rewarding for Pei, and he agreed immediately to work with the group again. The new project was the
Miho Museum, to display Koyama's collection of

.
One major challenge was the approach to the museum. The Japanese team proposed a winding road up the mountain, not unlike the approach to the NCAR building in Colorado. Instead, Pei ordered a hole cut through a nearby mountain, connected to a major road via a bridge suspended from ninety-six steel cables and supported by a post set into the mountain. The museum itself was built into the mountain, with 80 percent of the building underground.
When designing the exterior, Pei borrowed from the tradition of Japanese temples, particularly those found in nearby

. He created a concise
spaceframe wrapped into French limestone and covered with a glass roof. Pei also oversaw specific decorative details, including a bench in the entrance lobby, carved from a 350-year-old ''
keyaki'' tree. Because of Koyama's considerable wealth, money was rarely considered an obstacle; estimates at the time of completion put the cost of the project at US$350 million.
During the first decade of the 2000s, Pei designed a variety of buildings, including the
Suzhou Museum near his childhood home. He also designed the

Once again, Pei sought to combine new design elements with the classical aesthetic most appropriate for the location of the building. The sand-colored rectangular boxes rotate evenly to create a subtle movement, with small arched windows at regular intervals into the limestone exterior. Inside, galleries are arranged around a massive atrium, lit from above. The museum's coordinators were pleased with the project; its official website describes its "true splendour unveiled in the sunlight," and speaks of "the shades of colour and the interplay of shadows paying tribute to the essence of Islamic architecture".

Pei's career ended with his death in May 2019, at 102 years of age.
Style and method
Pei's style was described as thoroughly modernist, with significant cubist themes. He was known for combining traditional architectural principles with progressive designs based on simple geometric patterns—circles, squares, and triangles are common elements of his work in both plan and elevation. As one critic wrote: "Pei has been aptly described as combining a classical sense of form with a contemporary mastery of method." In 2000, biographer Carter Wiseman called Pei "the most distinguished member of his Late-Modernist generation still in practice".
[Wiseman, p. 323.] At the same time, Pei himself rejected simple dichotomies of architectural trends. He once said:
Pei's work is celebrated throughout the world of architecture. His colleague
John Portman once told him: "Just once, I'd like to do something like the
East Building."
But this originality did not always bring large financial reward; as Pei replied to the successful architect: "Just once, I'd like to make the kind of money you do."
[Quoted in Wiseman, p. 215.] His concepts, moreover, were too individualized and dependent on context to have given rise to a particular school of design. Pei referred to his own "analytical approach" when explaining the lack of a "Pei School".
"For me," he said, "the important distinction is between a stylistic approach to the design; and an analytical approach giving the process of due consideration to time, place, and purpose ... My analytical approach requires a full understanding of the three essential elements ... to arrive at an ideal balance among them."
