Ralph Johnson

FAIA, LEED AP
Principal, Firmwide Design Director, Chicago

Ralph Johnson’s portfolio of award-winning work around the world has earned him a rightful place in the pantheon of modern architecture legends. Throughout his more than 50-year career, Ralph has designed some of the world’s most quietly iconic buildings, from 100 Riverside Plaza in his hometown of Chicago to the Shanghai Natural History Museum.

His buildings have transformed both place and community, inspiring a generation of architects to pursue beauty and high performance through meticulous study of site and form. Outside of architecture, Ralph takes inspiration from minimalist art of the 1960s. He lives by the philosophy that the best thing anyone can do is learn from their toughest challenges.

Ralph grew up on the South Side of Chicago, just down the street from Frank Lloyd Wright’s R.W. Evans House. He found the design of the house fascinating, and by the time he reached grade school, he had already decided to become an architect. Never one to stray from his goals, Ralph became the first in his family to go to college. He received his Bachelor of Architecture from the University of Illinois at Urbana-Champaign and his Master of Architecture from Harvard University.

In 1976, Ralph joined Perkins&Will—now 2,700 people strong—where he is Firmwide Design Director. He was inducted into the prestigious National Academy of Design in 2015 and received the AIA Chicago Lifetime Achievement Award in 2022. He has been the subject of four monographs, including Architecture in a Rapidly Changing World (2026).

“Architecture to me is about layering the practical into the artistic. Some architects are known for a specific style, a certain form or expression; my work, while rooted in Modernism, is based on context—a concept that is the foundation of my approach.“
