Henry Hornbostel’s last great work was his biggest, a late-art-deco skyscraper towering next to his own City-County Building. The original lobby has been replaced by a 1980s parody of an art-deco interior, but the building is otherwise much as Hornbostel imagined it in the late 1930s. On top is a big red light that blinks “P-I-T-T-S-B-U-R-G-H” in Morse code all night—a landmark that guided commercial aircraft from a hundred miles away in the early days of aviation.
