Ten years ago I joined the jury of the Driehaus Prize for Classical Architecture. I came to know Richard H. Driehaus (1942-2021) as padrone of the prize and as a munificent host on my periodic trips to Chicago. But his passing this week touched me in an unexpected way—I had lost a friend. Like anyone who met him, I was impressed by his curiosity and intelligence. And by his generosity. Over the years I occasionally sent him pieces of my writing that I thought would interest him—and everything interested him: people, buildings, art, cars. I once introduced him to a public gathering as a true son of the great Daniel Burnham. Like Burnham, Richard never made small plans, and like him he leaves a large legacy, not only in his native Chicago, but around the world.
