he was of the opinion that the style of those who replicated Mies was substandard. He was also at the forefront of heritage preservation in Chicago, having been galvanized by the demolition of the Chicago Stock Exchange Building in 1972. He spearheaded the effort to protect Glessner House, the last surviving building designed by Henry Hobson Richardson in Chicago, spending seven years to refurbish it. The structure went on to be re-adapted as the base for the Chicago chapter of the American Institute of Architects. The Museum of Contemporary Art, Chicago, organized a reunion of the Chicago Seven in 2005 to discuss the contemporary state of Chicago architecture, Celebrating 25 Years of the Chicago Seven''. As part of the panel discussion, Nagle commented on the state of affairs that prompted the intervention of the Chicago Seven: "It wasn't Mies that got boring. It was the copiers that got boring.... You got off an airplane in the 1970s, and you didn't know where you were." In his interview as part of the Chicago Architects Oral Histories Project, Nagle spoke of the work his office was doing at that time: "I remember the reaction to [one of our projects] was, Wow, these guys are changing; they're doing things that are different from what they did before; there's a new movement afoot. So we all got excited about moving on to something that was different. A lot of it really had to do with history. That's what the postmodernist movement was all about. The appreciation of history made us all much better architects. One of the things that I find from 1930s and 1940s architecture is that the people who have gone through the Beaux-Arts understand the history of architecture and for the good architects, such as Alvar Aalto and Corbusier, it probably made them better modernists because they didn’t learn through abstraction. Gropius was wrong. You should know your history and understand and be able to operate on those levels and then go on to do your own thing and presumably do something that’s original." Personal life Nagle was married to Ann Steinbaugh until her death in 2007. They met while studying at Stanford, and resided for over three decades in a brick house in Lincoln Park that he designed in 1979. Together, they had two children: Kathleen and James Jr. Nagle died on January 19, 2021. He was 83, and suffered
