United States Embassy in Tokyo, Japan, was designed by Pelli in 1972 and completed in 1975. While practicing in Los Angeles, Pelli taught in the architecture program at UCLA. 1977–1989 In 1977, Pelli was selected to be the dean of the Yale School of Architecture in New Haven, Connecticut, and served in that post until 1984. Shortly after Pelli arrived at Yale, he won the commission to design the expansion and renovation of the Museum of Modern Art in New York, which resulted in the establishment of his own firm, Cesar Pelli & Associates. The museum's expansion/renovation and the Museum of Modern Art Residential Tower were completed 1984; the World Financial Center in New York, which includes the grand public space of the Winter Garden, was completed in 1988. Among other significant projects during this period are the Crile Clinic Building in Cleveland, Ohio, completed 1984; Herring Hall at Rice University in Houston, Texas (also completed 1984); completion in 1988 of the Green Building at the Pacific Design Center in West Hollywood, California; completion of the Bank of America Corporate Center in Charlotte, North Carolina in 1989; and the construction of the Wells Fargo Center in Minneapolis, Minnesota, in 1989. 1990–2005 Pelli was named one of the ten most influential living American Architects by the American Institute of Architects in 1991. In 1995, he was awarded the American Institute of Architects Gold Medal. In May 2004, Pelli was awarded an honorary Doctor of Humane Letters degree from the University of Minnesota Duluth where he designed Weber Music Hall. In 2005, Pelli was honored with the Connecticut Architecture Foundation's Distinguished Leadership Award. Buildings designed by Pelli during this period are marked by further experimentation with a variety of materials (most prominently stainless steel) and his evolution of the skyscraper. One Canada Square at Canary Wharf in London (opened in 1991); Plaza Tower in Costa Mesa, California (completed 1991); and the NTT Headquarters in Tokyo (finished 1995) were preludes to a landmark project that Pelli designed for Kuala Lumpur, Malaysia. The Petronas Towers were completed in 1997, sheathed in stainless steel and reflecting Islamic design motifs. The dual towers were the world's tallest buildings until 2004. That year, Pelli received the Aga Khan Award for Architecture for the design of the Petronas Towers Pelli's design for the National Museum of Art in Osaka, Japan, was completed 2005, the same year that Pelli's
