Helmut Jahn, 81, managing principal of JAHN Architects based in Chicago and Berlin, died May 8 after a bicycle accident near his home in St. Charles, Ill.
“Jahn was one of the most inventive Chicago architects,” Chicago Mayor Lori E. Lightfoot said in a May 9 tweet. [His] impact on the city—from the skyline to the O’Hare tunnel—will never be forgotten. His architectural footprint will be felt and seen across the globe for generations to come.”
