The December 6, 1931 Daily Capital News and Post-Tribune (Jefferson City, MO) ran a short blurb about Francis Keally's predictions for the city of 2031. Keally (1889-1978) was an architect who worked on the Oregon state capitol building in Salem, which was completed in 1938.
Francis Keally thinks that our future cities will spread out over great areas like monstrous eagles. One hundred years from today we shall have no batteries of skyscrapers to point out to our trans-Atlantic visitors. On the contrary our future cities, because of the aerial eye, will be flat-topped, and two out of every three buildings will serve as some kind of landing area for a super-auto gyroplane or a transcontinental express. What towers there are will be built at a great distance from the airports and will serve as mooring masts for giant dirigibles. The architects of our future aerial cities may have to go back to places like Constantinople and Fez for their inspiration of these future flat-topped aerial cities where one finds a low horizontal character to the entire city, occasionally broken here and there by a praying tower or a minaret.
Francis Keally also had an idea in the August, 1931 issue of Modern Mechanics for glass banks.
