chicago’s first international airport
A contestant in Chicago's first official International Aviation Meet, August, 1911. With NASCAR racing in Grant Park earlier this summer and Chicago's annual Air + Water Show warming up over the lake, this seems an appropriate time to point out that Chicago has a long history of racing and aviation in its otherwise pastoral 'front yard.' My current research project is a history of Chicago's airports.

This!!!
So much is alternately bananas and enraging and terrifying, but over in my lane I know this. Americans want, in fact crave, real, full, complex histories that reflect the kind of complexity they face daily. Pablum appeals to v few. That's why we do this work. Heading into #July4.

Was this mill in Shrewsbury, England, the "first skyscraper?" Well, no, but it made an essential contribution to high-rise construction and engineering, nonetheless. Happy to help set the record straight (-ish) in the ‪New York Times today.

The largest paying crowd in the history of Wrigley Field was the day Jackie Robinson made his debut. Wrigley is the only park left Jackie played a game in. Mike Ryoko was a kid at that ballpark that day and he wrote about it. Take a minute and read this today.

What Vance is doing here is ENORMOUS disinformation. International students at the undergrad level typically pay full tuition, which subsidizes tuition for American students on financial aid by keeping tuition costs lower. At the grad level, domestic students are harder to recruit!
"Last week, Vance said foreign students at elite U.S. universities are 'not just bad for national security,' but also 'bad for the American dream, for American kids who want to go to a nice university but can’t because their spot was taken by a foreign student.'"

University Towers, NYC. I.M. Pei. 1966-1967. JSTOR Happy to announce that after a couple of years of great conversations, deep dives into obscure 1920s issues of Cement Age, and ace model-making by a student team here, The Modern Concrete Skyscraper is opening this week at the Skyscraper Museum in New York. Carol Willis, the Museum's Director and Founder, approached me about helping to curate an exhibition that would be a 'gentle corrective' to the idea that the skyscraper's evolution was primarily a steel story.

N. Clifford Ricker and “The Elements of Construction”
Any University of Illinois School of Architecture graduate will recognize the name Nathan Clifford Ricker. Our library and two school publications are named for him. We’ll waste no opportunity to point out that he was the first American to receive a home-grown architectural degree—in 1873. He designed several key buildings on the Urbana-Champaign campus, in addition to his own home nearby, and he stayed on as a faculty member (1916), director of the nascent architecture program (1910), and general guiding spirit until 1922.

Construction of the U.S. Supreme Court Building in December, 1933. (Architect of the Capitol). Greenough's argument against "the adoption of admired forms and models for purposes not contemplated in their invention," particularly the use of classical architecture for modern programs, found a resonant application nearly a century after his death when the Maison Carree was once again the model for a monumental government structure.

“american architecture” (part 1)
Every four or eight years, the age-old question "in what style should we build" seems to enter political discourse; modernism (or in the current iteration, a straw-man "brutalism") and classicism come to stand in for left vs. right in a way that seems to encapsulate arguments about individualism, tradition, beauty, and whatever else is the argument du jour. To be clear: there is good classicism and good modernism.
