Ieoh Ming Pei (born April 26, 1917), commonly known as I. M. Pei, is a Chinese American architect often called a master of modern architecture. Born in Canton, China and raised in Hong Kong and Shanghai, Pei drew inspiration at an early age from the gardens at Suzhou. In 1935, he moved to the United States and enrolled in the University of Pennsylvania's architecture school, but quickly transferred to the Massachusetts Institute of Technology. He was unhappy with the focus at both schools on Beaux-Arts architecture, and spent his free time researching emerging architects, especially Le Corbusier. After graduating, he joined the Harvard Graduate School of Design (GSD) and became friends with the Bauhaus architects Walter Gropius and Marcel Breuer. In 1939, he married Eileen Loo, who had introduced him to the GSD community. They have been married for over seventy years, and have four children, including architects C.C. "Didi" Pei and L.C. "Sandi" Pei.

Pei spent ten years working with New York real estate magnate William Zeckendorf before establishing his own independent design firm that eventually became Pei Cobb Freed & Partners. Among the early projects on which Pei took the lead were the L'Enfant Plaza Hotel in Washington, DC and the Green Building at MIT. His first major recognition came with the National Center for Atmospheric Research in Colorado; his new stature led to his selection as chief architect for the John F. Kennedy Library in Massachusetts. He went on to design Dallas City Hall and the East Building of the National Gallery of Art.

He returned to China for the first time in 1974 to design a hotel at Fragrant Hills, and designed a skyscraper in Hong Kong for the Bank of China fifteen years later. In the early 1980s, Pei was the focus of controversy when he designed a glass-and-steel pyramid for the Musée du Louvre in Paris. He later returned to the world of the arts by designing the Morton H. Meyerson Symphony Center in Dallas, the Miho Museum in Japan, the Suzhou Museum in Suzhou, and the Museum of Islamic Art in Qatar.

Pei has won a wide variety of prizes and awards in the field of architecture, including the AIA Gold Medal in 1979, the first Praemium Imperiale for Architecture in 1989, and the Lifetime Achievement Award from the Cooper-Hewitt, National Design Museum in 2003. In 1983, he won the Pritzker Prize, sometimes called the Nobel Prize of architecture.

Childhood

As a child, Pei found the Shizilin Garden in Suzhou to be "an ideal playground".

Pei's ancestry traces back to the Ming Dynasty, when his family moved from Anhui province to Suzhou. Finding wealth in the sale of medicinal herbs, the family stressed the importance of helping the less fortunate. Ieoh Ming Pei was born on April 26, 1917 to Tsuyee Pei and Lien Kwun, and the family moved to Hong Kong one year later. The family eventually included five children. As a boy, Pei was very close to his mother, a devout Buddhist who was recognized for her skills as a flautist. She invited him, his brothers, and his sisters to join her on meditation retreats. His relationship with his father was less intimate. Their interactions were respectful but distant.

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.

At the age of ten, Pei moved with his family to Shanghai after his father was promoted. Pei attended Saint Johns Middle School, run by Protestant missionaries. Academic discipline was rigorous; students were allowed only one half-day each month for leisure. Pei enjoyed playing billiards and watching Hollywood movies, especially those of Buster Keaton and Charlie Chaplin. He also learned rudimentary English skills by reading the Bible and novels by Charles Dickens.

Pei describes the architecture of Shanghai's Bund waterfront area (seen here in a 2006 photo) as "very much a colonial past".

Shanghai's many international elements gave it the name "Paris of the East". The city's global architectural flavors had a profound influence on Pei, from the Bund waterfront area to the Park Hotel, built in 1934. He was also impressed by the many gardens of Suzhou, where he spent the summers with extended family and regularly visited a nearby ancestral shrine. The Shizilin Garden, built in the 14th century by a Buddhist monk, was especially influential. Its unusual rock formations, stone bridges, and waterfalls remained etched in Pei's memory for decades. He spoke later of his fondness for the garden's blending of natural and human-built structures.

Soon after the move to Shanghai, Pei's mother developed cancer. As a pain reliever, she was prescribed opium, and assigned the task of preparing her pipe to Pei. She died shortly after his thirteenth birthday, and he was profoundly upset. The children were sent to live with extended family; their father became more consumed by his work and more physically distant. 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

Pei said that "Bing Crosby's films in particular had a tremendous influence on my choosing the United States instead of England to pursue my education."

As Pei neared the end of his secondary education, he decided to study at an overseas university. He was accepted to a number of schools, but decided to enroll at the University of Pennsylvania. 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, which differed tremendously from the academic atmosphere in China. "College life in the U.S. seemed to me to be mostly fun and games", he said in 2000. "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. I decided that was the country for me."

In 1935 Pei boarded the SS President Coolidge and sailed to San Francisco, then traveled by train to Philadelphia. What he found, however, differed vastly from his expectations. Professors at the University of Pennsylvania based their teaching in the Beaux-Arts style, rooted in the classical traditions of Greece and Rome. Pei was more intrigued by modern architecture, and also felt intimidated by the high level of drafting proficiency shown by other students. He decided to abandon architecture and transferred to the engineering program at Massachusetts Institute of Technology (MIT). Once he arrived, however, the dean of the architecture school commented on his eye for design and convinced Pei to return to his original major.

MIT's architecture faculty was also focused on the Beaux-Arts school, and Pei found himself uninspired by the work. In the library he found three books by the Swiss-French architect Charles-Édouard Jeanneret-Gris, better known as Le Corbusier. Pei was inspired by the innovative designs of the new International style, characterized by simplified form and the use of glass and steel materials. Le Corbusier visited MIT in November 1935, an occasion which powerfully affected Pei: "The two days with Le Corbusier, or 'Corbu' as we used to call him, were probably the most important days in my architectural education." Pei was also influenced by the work of US architect Frank Lloyd Wright. In 1938 he drove to Spring Green, Wisconsin, to visit Wright's famous Taliesin building. After waiting for two hours, however, he left without meeting Wright.

Pei attempted to meet renowned architect Frank Lloyd Wright, but gave up after waiting for two hours.

Although he disliked the Beaux-Arts emphasis at MIT, 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." Pei received his Bachelors of Architecture degree in 1940. He planned to return to China immediately afterward, but the Second Sino-Japanese War forced him to change his plans. Pei's father urged him to remain in the United States, and he worked for two years at the Boston engineering firm of Stone & Webster.

While visiting New York City in the late '30s, Pei met a Wellesley College student named Eileen Loo. They began dating and they married in the spring of 1942. She enrolled in the landscape architecture program at Harvard University, and Pei was thus introduced to members of the faculty at Harvard's Graduate School of Design (GSD). He was excited by the lively atmosphere, and joined the GSD in December 1942.

Less than a month later, Pei suspended his work at Harvard to join the National Defense Research Committee, which coordinated scientific research into US weapons technology during World War II. Pei's background in architecture was seen as a considerable asset; one member of the committee told him: "If you know how to build you should also know how to destroy." The fight against Germany was ending, so he focused on the Pacific War. The US realized that its bombs used against the stone buildings of Europe would be ineffective against Japanese cities, mostly constructed from wood and paper; Pei was assigned to work on incendiary bombs. Pei spent two and a half years with the NDRC, but has revealed few details.

In 1945 Eileen gave birth to a son, T'ing Chung; she withdrew from the landscape architecture program in order to care for him. Pei returned to Harvard in the autumn of 1945, and received a position as assistant professor of design. The GSD was developing into a hub of resistance to the Beaux-Arts orthodoxy. At the center were members of the Bauhaus, a European architectural movement that had advanced the cause of modernist design. The Nazi regime had condemned the Bauhaus school, and its leaders left Germany. Two of these, Walter Gropius and Marcel Breuer, took positions at the Harvard GSD. Their iconoclastic focus on modern architecture appealed to Pei, and he worked closely with both men.

One of Pei's design projects at the GSD was a plan for an art museum in Shanghai. He wanted to create a mood of Chinese authenticity in the architecture without using traditional materials or styles. The design was based on straight modernist structures, organized around a central courtyard garden, with other similar natural settings arranged nearby. It was very well received; Gropius, in fact, called it "the best thing done in [my] master class". Pei received his master's degree in 1946, and taught at Harvard for another two years.

Career
1948–55: Early career with Webb and Knapp

William Zeckendorf (shown here in the office redesigned by his architectural team) hired Pei after ordering a search for what he called "the greatest unknown architect in the country".

In the spring of 1948 Pei was recruited by New York real estate magnate William Zeckendorf 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 with funding from the Housing Act of 1949. Pei's design was based on a circular tower with concentric rings. The areas closest to the supporting pillar handled utilities and circulation; 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 moved beyond the model stage.

Pei finally saw his architecture come to life in 1950, when he designed a corporate building for Gulf Oil in Atlanta, Georgia. His use of marble for the exterior curtain wall brought praise from the journal Architectural Forum. Pei's designs echoed the work of Mies van der Rohe in the beginning of his career as also shown in his own weekend-house in Katonah 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 Henry N. Cobb and Ulrich Franzen. They set to work on a variety of proposals, including the Roosevelt Field Shopping Mall. The team also redesigned the Webb and Knapp office building, transforming Zeckendorf's office into a circular space with teak walls and a glass clerestory. They also installed a control panel into the desk that allowed their boss to control the lighting in his office. The project took one year and exceeded its budget, but Zeckendorf was delighted with the results.

Pei wanted the open spaces and buildings of L'Enfant Plaza to be "functionally and visually related" to one another.

In 1952 Pei and his team began work on a series of projects in Denver, Colorado. The first of these was the Mile High Center, which compressed the core building into less than twenty-five 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," he said later, "and about the city as a living organism." These lessons, he said, became essential for later projects. The hyperbolic paraboloid structure was removed when the Denver Pavilions facility was constructed. In 1982, he returned to design the 16th Street Mall, essentially converting a street into a pedestrian only shopping district.

Pei and his team also designed a united urban area for Washington, D.C., L'Enfant Plaza (named for French-American architect Pierre Charles L'Enfant). Pei's associate Araldo A. Cossutta was the lead architect for the plaza's North Building (955 L'Enfant Plaza SW), South Building (490 L'Enfant Plaza SW), and Center Building (475 L'Enfant Plaza SW; now the United States Postal Service headquarters). (Vlastimil Koubek was the architect for the East Building or L'Enfant Plaza Hotel, located at 480 L'Enfant Plaza SW). The team set out with a broad vision that was praised by both the Washington Post and Washington Star (which rarely agreed on anything), but funding problems forced revisions and a significant reduction in scale.

1955–90: I. M. Pei & Associates
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 architectural models. They took on the Kips Bay residential area on the east side of Manhattan, where Pei set up Kips Bay Towers, two large long towers of apartments with recessed windows (to provide shade and privacy) in a neat grid, adorned with rows of trees. Pei involved himself in the construction process at Kips Bay, even inspecting the bags of concrete to check for consistency of color.

Pei was commissioned to design the Luce Memorial Chapel in Taiwan by the same organization that ran the middle school he had attended in Shanghai.

The company continued its urban focus with the Society Hill project in central Philadelphia. Pei designed the Society Hill Towers, a three-building residential block injecting cubist design into the 18th-century milieu of the neighborhood. As with previous projects, abundant green spaces were central to Pei's vision, which also added traditional townhouses to aid the transition from classical to modern design.

From 1958 to 1963 Pei and Ray Affleck developed a key downton block of Montreal in a phased process that involved one of Pei's most admired structures in the commonwealth, the cruciform tower known as the Royal Bank Plaza (Place Ville Marie). According to the Canadian Encyclopedia "its grand plaza and lower office buildings, designed by internationally famous US architect I.M. Pei, helped to set new standards for architecture in Canada in the 1960s ... The tower's smooth aluminum and glass surface and crisp unadorned geometric form demonstrate Pei's adherence to the mainstream of 20th-century modern design."

Although these projects were satisfying, Pei wanted to establish an independent name for himself. In 1959 he was approached by MIT to design a building for its Earth science program. The Green Building continued the grid design of Kips Bay and Society Hill. The pedestrian walkway at the ground floor, however, was prone to sudden gusts of wind, which embarrassed Pei. "Here I was from MIT," he said, "and I didn't know about wind-tunnel effects." At the same time, he helped design the Luce Memorial Chapel in Taiwan, which broke severely from the cubist designs of his urban projects.

The challenge of coordinating these 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.

Pei said he wanted the Mesa Laboratory of the National Center for Atmospheric Research to look "as if it were carved out of the mountain".

 NCAR and Kennedy Library
Pei was able to return to hands-on design when he was approached in 1961 by Walter Orr Roberts to design the new Mesa Laboratory for the National Center for Atmospheric Research outside Boulder, Colorado. The project differed from Pei's earlier urban work; it would rest in an open area in the foothills of the Rocky Mountains. He drove with his wife around the region, visiting assorted buildings and surveying the natural environs. He was impressed by the United States Air Force Academy in Colorado Springs, but felt it was "detached from nature".

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.

Pei also drew inspiration from the Mesa Verde cliff dwellings of the Ancient Pueblo Peoples; he wanted the buildings to exist in harmony with their natural surroundings. To this end, he called for a rock-treatment process that could color the buildings to match the nearby mountains. He also set the complex back on the mesa overlooking the city, and designed the approaching road to be long, winding, and indirect.

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; still, Pei was frustrated. His second attempt, however, fit Roberts' vision perfectly: a spaced-out series of clustered buildings, joined by lower structures and complemented by two underground levels. The complex uses many elements of cubist design, and the walkways are arranged to increase the probability of casual encounters among colleagues.

As with NCAR, Pei combined elements of cubism and natural harmony when designing the dormitories at New College of Florida in the mid-1960s.
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 caused cracks in the buildings which were expensive to repair. Still, both architect and project manager were pleased with the final result. Pei refers to the NCAR complex as his "breakout building", and he remained friends with Roberts until the scientist died in March 1990.

The success of NCAR brought renewed attention to Pei's design acumen. He was recruited to work on a variety of projects, including the S. I. Newhouse School of Public Communications at Syracuse University and the Sundrome terminal at Idlewild Airport in New York City, and dormitories at New College of Florida.

After President John F. Kennedy was assassinated in November 1963, his family and friends discussed how to construct 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. The first was scope. 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 considers the John F. Kennedy Library "the most important commission" in his life.

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 US. Mrs. Kennedy liked the design, but resistance began in Cambridge, the first proposed site for the building, as soon as the project was announced. Many community members worried that the library would become a tourist attraction, causing particular problems with traffic congestion. Others worried that the design would clash with the architectural feel of nearby Harvard Square. By the mid-70s, 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."

Finally the project moved to Columbia Point, near the University of Massachusetts Boston. 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." Perhaps the most important consequence of the Kennedy project for Pei was his elevation in the public's consciousness as an architect of note
