Helmut Jahn was one of the most influential architects in shaping late-20th-century Chicago, blending the legacy of Miesian modernism with bold postmodern experimentation to create buildings that transformed the city’s architectural identity and projected Chicago’s influence onto the world stage.

German-American postmodernist architect Helmut Jahn (1940-2021) is a leading postmodern architect responsible for scores of projects internationally. Retrospective exhibition Helmut Jahn: Life + Architecture held at the Chicago Architecture Center, July 23, 2021, through October 31, 2021. Following his passing in May 2021, the exhibition showcased Jahn’s collaborative engineering process and featured personal items, scaled architectural models, and photography of his work—such as O’Hare International Airport’s Terminal 1. The angled, sail-like canvas banner walls were custom-designed as a subtle nod to Jahn’s passionate love for professional sailboat racing.

Introduction.

Helmut Jahn was famous in Chicago and around the world for his prolific postmodern architecture particularly his work in steel and glass.

Born in Germany near Nuremberg, in 1940, Jahn graduated from Technische Hochschule in Munich and moved to Chicago in 1966. Jahn arrived in Chicago just as “downtown development” during the administration of Mayor Richard J. Daley (1902-1976) was finding its greatest momentum. Jahn began to study under Ludwig Mies van der Rohe (1886-1969) at the Illinois Institute of Technology (IIT) and, in 1967, joined Charles (C.F.) Murphy Associates which later became Murphy/Jahn. The younger man would carry on the powerful influence and energy of these Chicago personalities for building big, creatively, and prolifically for the next fifty years into the first quarter of the 21st century. Jahn would add his own significant contribution and footprint in Chicago and around the nation and world in those same long years of his activity.

One of Jahn’s early projects in his first years in Chicago was McCormick Place. The original concrete and steel permanent exposition hall on the lakefront that opened in 1960 was destroyed in a fire in January 1967, just as Jahn was starting to work as a professional architect. Named for Col. McCormick of the Chicago Tribune, the newspaper owner and publisher had boosted the idea of a permanent exposition hall on Chicago’s lakefront for years prior to his death in 1955.

Jahn’s Chicago career coincided with the city’s continued downtown expansion following landmark projects such as the John Hancock Center and Sears Tower.

Jahn had come to Chicago at an exciting time to be building there — during Jahn’s first years in Chicago the John Hancock Building was completed in 1969 and the Sears Tower, the tallest building in the world for the next 24 years, was completed in 1974. In 1971, C.F. Murphy completed the new and massive McCormick Place, a powerful steel and glass structure with enormous cantilever eaves, on the same lakefront site as the old exposition hall. Out of that single successful building project, Helmut Jahn and the rest of the world saw the significant development in Chicago that would blossom around this important and functional modern architecture over ensuing decades — including the North building constructed across Lake Shore Drive in 1986; the South building built in 1996; a hotel built in 1998; the massive West building built in 2007; and, in 2017, the Wintrust Arena.

In the mid 1980’s one of Jahn’s most significant creations was the James R. Thompson Center in Chicago. Aesthetically grandiose and controversial, the “State of Illinois Building” was put up for sale in 2021 by the administration of Governor J.B. Pritzker, citing its historically high operating and maintenance costs.

Jahn designed the 23-story addition to the Chicago Board of Trade in 1980 and Accenture Tower at 500 W. Madison in the West Loop which opened in 1987. Across the nation and world Helmut Jahn’s fresh, grand, and innovative designs have made their way into the annals of postmodern architecture. Any complete list of Helmut Jahn’s active and completed projects extends necessarily into the many scores. A list of notable buildings could include the 1999 K St. NW, a 12-story structure, in Washington D.C. completed in 2009; the twin 37-story Veers Towers in Las Vegas, Nevada opened in 2010; and, in his native Germany, the 63-story Messeturm in Frankfurt opened in 1990 and the Sony Center, a complex of eight buildings, in Potsdamer Platz in Berlin completed in 2000. The hard-driving list goes on…and on.

In Chicago Jahn designed the exposed steel frame United Airlines Terminal 1 at O’Hare International Airport between 1985 and 1988. Air travelers for decades have enjoyably traversed its entertaining walkway connecting concourses that include moving sidewalks, colorful lighting and futuristic sounds.

At the time of his death at 81 years old on May 8, 2021 in a bike road accident in the far western suburbs of Chicago, Helmut Jahn was working on a 74-story residential building in Chicago at 1000 S. Michigan. It was scheduled to be opened in 2022 but its construction was already delayed because of the Covid-19 pandemic that postponed construction. Helmut Jahn taught at IIT, the University of Illinois-Chicago, Harvard University, and Yale University. In 2012 Murphy/Jahn became JAHN and, according to a recent report from Dun & Bradstreet, the firm had a total of 55 employees and generated a little over $6 million in annual sales.

Xerox Center, 55 West Monroe, Chicago, 1977-1980.

In what was one of Helmut Jahn’s first great urban achievements, the 40-story office tower on an important corner in downtown Chicago was built on speculation and soon took the name of its major tenant (Xerox). The sleek and simple curtain wall of enameled off-white fluoropolymer aluminum panels and reflective glass slide over a reinforced concrete structure and around its soft postmodern corners in contrast to the modernist box.

The tower is fitted to its site where the building’s corner is exaggerated at street level with varying glaze percentages, and the white-black-silver palette of the lobby follows a diagonal pattern (also on the roof) in contrast to the exterior curvilinear design.

Silver double-glazed reflective glass pays homage to 1950’s and 1960’s Chicago modernism and the Xerox building’s closest neighbors: the kitty-corner Inland Steel Building (1954-1958, Skidmore, Owings and Merrill) and, directly across to the north, the First National (today, Chase) Bank building (1964-1969, C.F. Murphy Associates with Perkins and Will).

Some have observed that Jahn’s curving tower may have been inspired by Louis Sullivan’s 1899 Schlesinger and Mayer department store building on State Street (what became in 1904 Carson, Pirie, Scott and Company Building and today is The Sullivan Center). The 1980 project’s original conception was for two curvilinear towers though obviously only one was constructed obfuscating and negating the original design’s uniquely bold impacts.

The glass and aluminum are arranged to alternate in horizontal bands which have modernist predecessors in Chicago and Europe. Hidden from the street view are more diagonals that cut a pattern across the roof. The building is a major transition for Jahn who, steeped in mid-20^th century Modernism, harkened back to earlier 1920s modernist sources for the 55 W. Monroe (Xerox) building.

Helmut Jahn, State of Illinois (Thompson) Center, 100 W. Randolph, Chicago, Illinois, 1979-1985. The building is massive at 1.15 million square feet. The rounded facade was intended to embody the traditional architectural history of monumental rotundas and domes. When it was built in the early 1980s it was one of the most exciting projects taking place downtown. Sitting across the street from a classical revival City Hall (1911) and a modernist Daley Center (1965), the postmodern 1980’s monstrosity by Murphy/Jahn was criticized for being out of context in the neighborhood. Yet, over the following decades, negative criticism increasingly faded. May 2014. Author’s photograph. 4.75 mb

There were mixed reviews for Helmut Jahn’s massive semi-circular Thompson Center at 100 W. Randolph completed in 1985. The criticism begins at its entrance where Jahn saw placed “Outsider” French artist Jean Dubuffet’s fiberglass Monument with Standing Beast. During the building’s planning and construction some of the architect’s dazzling concepts met with resistance from contractors. For example, the contractors prevailed over Jahn’s idea for a completely locked-down outer skin using silicone glazing. In the final construction the appearance of red, white, and blue locked-down skin belies the several places throughout the design where windows are made to be opened. Inside, though its soaring 17-story atrium is airy and impressive exposing floors that hold various state bureaucracy—and signaling the idea of state government’s day-to-day practice towards transparency — the practicalities of the new building’s heating and cooling design proved seriously problematic during Chicago’s summer heat and winter cold though that major issue appeared to be eventually resolved. In 2021 Jahn’s mega-structure has been put up for sale by Illinois Gov. J.B. Pritzker from Chicago citing that the building costs hundreds of millions of dollars to operate and maintain.

Helmut Jahn, One South Wacker Drive, Chicago, Illinois, 1979-1982. On a corner site, Jahn’s design is a freely translated interpretation of a 1920s stepped back tower with the building’s skin a stylized exaggeration of vertical windows and stone facades of the same 1920s’ period structures.

To the left is UBS Tower (1 N. Wacker) built in 2001 and to the right is Hyatt Center ( 71 S. Wacker) built in 2005. At 42 years old, Jahn spoke of his building at 1 S. Wacker as a synthesis of two major Chicago architectural styles—that of Louis Sullivan (1856-1924) and, Jahn’s mentor and fellow German, Mies van der Rohe (1886-1969). The building is a concrete stepped-back 50-story building with a curtain wall of dark glass defining the vertical bands of windows. Its vision remains fresh and stunning as it sits majestically between two postmodern buildings built in Chicago a generation later. The author’s photograph was taken on May 25, 2014.

Floors in each section of the stepped back tower are of three different sizes, each six thousand square feet less as the building ascends. The setbacks’ atria allow in natural daylight. August 2021. Author’s photograph. 78% 7.77mb _9293

Jahn’s architecture often drew from Chicago traditions while reinterpreting them through contemporary materials and dramatic forms.

Originally called the State Street Village Dormitories, Jahn’s postmodern structure that anchors the campus to the east, consists of three five-story buildings. Jahn’s design was the first major architectural addition to the IIT campus since the early 1960’s. U.S. News & World Report called it one of the “coolest dorms in the nation.” Stretching one city block along busy State Street from 33rd to 34th Streets, Rowe Village is next to the El tracks whose Green Line zips back and forth to Chicago’s Loop. Each dorm building consists of two wings that flank an interior courtyard. The building is finished at the rear on 34^th street by an insulated five-story glass wall. Entry is through the courtyard which leads into a corridor that connects the two wings. It is built of reinforced concrete with the front elevations and roof dressed in custom corrugated stainless steel panels and tinted glass framed in aluminum. The building’s sleek curvature, three compartments and chained block-long length, reflects and evokes the image of a streamlined train making for a building as Art Moderne object in the Miesian tradition. From its rooftop the Rowe Village looks north for views of Chicago’s downtown skyline while the dorm offers suite-style living in a modern setting surrounded by the mind, serious and playful, of Helmut Jahn. The photograph was taken by the author on August 21, 2015.
