“Helmut Jahn, a German-born architect who designed buildings around the world but was most influential in his adopted hometown, Chicago, where he conceived of an extravagant downtown home to state government and the United Airlines terminal at O’Hare International Airport, died on Saturday in a traffic accident near the horse farm where he lived, in St. Charles, Ill. He was 81.”
