The trigger was pancreatic most cancers, mentioned his son Brian Kohn.
As president of the agency, broadly often called KPF, Mr. Kohn targeted on establishing and managing relationships with shoppers. In a 1986 profile, Paul Goldberger, then the structure critic for the New York Occasions, described Mr. Kohn as some of the efficient salesmen within the structure enterprise.
He usually began shows not with renderings of buildings however with images of KPF’s softball group, as if suggesting that the younger agency could be enjoyable to work with. Interviewing for an airport job in Philadelphia, he introduced that his mom, a Philadelphian, could be indignant if he wasn’t picked.
Time was valuable to Mr. Kohn, whom Goldberger described as “relaxed and informal on the floor, intense and pushed beneath it.” Earlier than he boarded a aircraft, he would study from a pleasant gate agent who else was in firstclass, then request a seat subsequent to the passenger almost certainly to wish an architect.
“I make certain I’m not pushy or annoying however I domesticate relationships like some folks domesticate orchids or bonsai — fastidiously and with the long run in thoughts,” he famous in “The World By Design,” his 2019 memoir written with Clifford Pearson.
His efforts paid off. Mr. Kohn persuaded among the nation’s largest firms — together with Procter & Gamble, Gannett and IBM — all of which had been searching for new headquarters — to decide on it over extra established corporations like Pei Cobb Freed & Companions and Skidmore, Owings & Merrill.
The outcomes had been, respectively, a beloved addition to the Cincinnati skyline, a hilltown-like compound in McLean, Va., and a zigzag formed constructing in Armonk, N.Y. (The IBM headquarters was designed in order that it couldn’t be expanded — IBM’s chairman and chief government, Louis Gerstner, mentioned he wished each a part of the corporate to develop besides its administrative ranks.)
In Washington, the agency was finest recognized for its World Bank headquarters. Accomplished in 1997, it was one of many first glass-fronted buildings in a metropolis the place most massive buildings had been both classical (prewar) or made from concrete (postwar). KPF’s constructing featured a 28-foot waterfall in an atrium behind a clear facade. Design-wise, it was additionally a leap ahead for the agency, which a number of years earlier had accomplished the awkwardly ornamented AARP headquarters within the District of Columbia.)
As KPF moved to the entrance rank of American structure, Mr. Kohn spoke in regards to the significance of staying in his lane of experience, with co-founder Invoice Pedersen taking the lead on the design aspect and Sheldon Fox (“probably the most organized individual I’ve ever met”) managing operations.
“I used to be probably the most outgoing of the three and the most important threat taker,” he wrote in his memoir. “Consequently, I took on the function of president and chief.” It helped that he appeared seasoned, sporting a helmet of white hair even in early center age.
Arthur Eugene Kohn, referred to as Gene since childhood, was born in Philadelphia on Dec. 12, 1930. His father was a medical researcher who misplaced his enterprise throughout the Melancholy.
His mom ran a gown store out of the household’s modest home, utilizing Eugene’s bed room as a altering room for purchasers. (She additionally painted and, when she turned 100 in 2002, the Guggenheim Museum, run by Mr. Kohn’s good friend Thomas Krens, mounted a show of 100 of her works.)
On the College of Pennsylvania Faculty of Design, he took lessons taught by the seminal mid-century architects Louis Kahn and Paul Rudolph and acquired a bachelor’s diploma in 1953. After three years within the Navy, he accomplished a grasp’s diploma at Penn in 1957 and labored at Philadelphia corporations earlier than transferring to New York in 1964.
He ultimately turned president of John Carl Warnecke & Associates, a California agency with a New York workplace, however he felt he didn’t have any actual energy. Its founder, a bon vivant who as soon as dated the widowed first girl Jacqueline Kennedy, held all of the strings, and pulled them in ways in which Mr. Kohn usually disliked.
In 1975 he left to begin his personal agency, Kohn and Associates, whereas attempting to recruit his Warnecke colleagues Pedersen and Fox. They established Kohn Pedersen Fox on July 4, 1976. Mr. Kohn later instructed Goldberger, “We had no enterprise. We had no enterprise card, no brochure, nothing. It was slightly loopy.”
However Mr. Kohn was scrappy. After he learn that the ABC broadcast community deliberate to show an previous armory on W. 66th Avenue in Manhattan right into a manufacturing facility, he referred to as the media firm, turning his agency’s newness into a bonus: KPF, he mentioned, might begin work on the job instantly. It did, and over the following twenty years, with Mr. Kohn managing the connection, the agency accomplished 17 tasks for ABC, together with a corporate campus round 66th Avenue.
In 1985, at a convention in San Francisco, Mr. Kohn heard an economist warn attendees, “In the event you’re not world by 1990, half of you’ll be out of enterprise.” Mr. Kohn started pondering of how to broaden past the USA.
4 years later, KPF opened an workplace in London, the place it was already engaged on a Fleet Avenue headquarters for Goldman Sachs. That constructing, which opened in 1991, was successful with critics, as was the agency’s 53-story DZ Bank Headquarters in Frankfurt, accomplished in 1993. By the top of the early Nineteen Nineties, KPF’s London workplace was competing with one of the best of the British corporations for jobs, and infrequently successful.
However the agency’s true golden age started with a mixed-use growth over a prepare station in Nagoya, Japan, accomplished in 2000 and often called JR Central Towers. With a foothold in Asia, the agency went on to open workplaces in Hong Kong, Shanghai, Singapore and Seoul.
In 2003, the agency accomplished a mixed-use complicated in Tokyo referred to as Roppongi Hills, a sort of Japanese-inflected Rockefeller Middle, with a 54-story tower at its coronary heart. Earlier than that undertaking had even damaged floor, its developer, Minoru Mori, received the precise to construct what could be referred to as the Shanghai World Monetary Middle in that metropolis’s Pudong district.
Mr. Pedersen designed a 1,600-foot-tall tower with a big spherical opening on the prime, paying homage to a conventional Chinese language moon gate. However to the mayor of Shanghai and others, the circle was disturbingly much like the rising solar of the Japanese flag. After a sequence of emergency conferences, the circle turned a trapezoid.
South Korea was one other land of alternative for KPF. Its tasks there included a Rodin museum, Samsung’s headquarters, a 1,400-acre-development referred to as New Songdo City, and the 1,800-foot Lotte World Tower. Lotte was one of many 10 tallest buildings on this planet, together with three KPF towers in China: the Ping An Finance Centre in Shenzhen; the CITIC (or China Zun) Tower in Beijing; and the Chow Tai Fook Finance Centre in Guangzhou.
By 2010, he mentioned, about 80 or 90 p.c of the agency’s work was outdoors the USA. But throughout that interval KPF was mentioned to be the only largest employer of architects in New York Metropolis, with some 450 folks in its workplace overlooking Bryant Park.
U.S. commissions picked up throughout the 2010s. KPF was chosen by the Associated Firms to do the grasp plan for its huge Hudson Yards growth on the west aspect of Manhattan, and to design three of Hudson Yards’ largest buildings.
Across the identical time, it started work on One Vanderbilt, a 1,600-foot tower adjoining to Grand Central Terminal. In Los Angeles, KPF could also be best-known for its odd renovation of the Petersen Automotive Museum, which lined a crimson stucco field in swoopy stainless-steel “stripes” suggesting velocity. It is without doubt one of the few KPF tasks for which Mr. Kohn took credit score as a designer.
His largest setback got here in 2009, when Lee Polisano, the pinnacle of KPF’s London’s workplace, introduced that he was leaving the agency and taking his staff with him. Mr. Kohn, then virtually 80, moved to London and labored feverishly to maintain staff and shoppers from following Polisano. About his profitable efforts, he wrote: “Some fights make you stronger.”
Mr. Kohn’s marriages to Barbara Schwartz and Diane Barnes resulted in divorce. In 2002, he wed Barbara Shattuck, an funding banker. Along with his spouse, with whom he shared houses in Montecito, Manhattan and Washington, Conn., survivors embody three youngsters from his first marriage, Brian Kohn of Fairfield, Conn., Steven Kohn of Westport, Conn., and Laurie Parkinson of Larchmont, N.Y.; and 9 grandchildren.
Mr. Kohn relinquished the presidency of KPF in 2003 and remained the agency’s chairman till earlier this yr. “I’ll be most pleased and proud after they don’t want me,” he mentioned of his youthful companions. “And most dissatisfied.”
