The Flatiron Building in New York, circa 1902-1910
Back in the 1990s, for New York Magazine, I interviewed the Manhattan-based engineer Donald Friedman, a specialist in the structural quirks of historic buildings, about what happens when a façade fails. He explained to me that when collapse is imminent, thereâll be âa rain of mortar before the bricks themselves actually start falling out. So itâs like, âWhy am I getting pelted by sand?â â I asked him how one should respond to that particular set of circumstances. He replied, âRun.â
I remember being fascinated by Friedmanâs intimacy with the guts of historic buildings and the impression he gave that his work as a preservation engineer was an unending series of epiphanies. So when I learned that heâd just published a new book, The Structure of Skyscrapers in America 1871-1900: Their History and Preservation (Association for Preservation Technology International), I was eager to read it. Not that Iâm the intended audience: Iâm not a preservationist per se nor am I involved with the restoration of historic buildings. But I am greatly interested in old skyscrapers as technological artifacts, and the way our complicated, often ambivalent relationship with innovative systems and materials has always shaped our cities.

Friedmanâs approach is deep and immersive. His book is an extensive journey through 19th-century building technology, much of it obscure and forgotten. The first half of the book explores the forces that led to the construction of the earliest skyscrapers (there were more of them than history acknowledges). And in a second, 200-page section, heâs documented 443 early examples of the form, with the requirements that they have been structurally complete by 1900 and stood at least 10 stories tall. Oddly, the one building that doesnât fit Friedmanâs formula is on the cover: Manhattanâs Flatiron building. At 22 stories, it was tall enough, but it was still under construction in 1902 when the photograph was taken. Friedman justifies its inclusion this way: âThat photo was too good to not use.â
Jacobs: What did you think you were looking for when you started working on this book over 20 years ago, and what did you find in the end?
Friedman: The final product doesnât look like what I thought it would look like originally. But it is exactly the same question through the whole 20-plus year march. That is, if you look at architectural histories they tend to give you a technological, determinist view of skyscrapers. Which is to say, people invented the steel frame so it got used. As the history of technology goes, thatâs not a very good story. So thatâs the first problem I had.
The second problem is those historiesâwith some exceptionsâtend to focus on the same 30 to 40 early skyscrapers. If you know the field you can rattle them off: the Home Insurance Building, American Surety, and so on. I thought, Thereâs got to be more to this story than that. I actually studied the history of technology a bit and thatâs not the way things work.

What do you mean by that?
The idea that somebody invents something is just about dead in the history of technology. Itâs an evolutionary process. Yes, inventors speed things up, they refocus, but nothing is from nothing.
There were already filament light bulbs before Edison got involved with that field. He improved them. He created a system where they would work. He did all sorts of useful things, but he didnât invent the filament light bulb.
So the hero inventor or hero architect is convenient for telling a story, but it isnât necessarily the real story?
Exactly. The second problem was the limited number of buildings. In engineering, when you donât know how to analyze something, you can always fall back on brute force and say Iâll start from scratch and analyze everything.
So I said, âWhat if I just look for all of the buildings in the country that meet some definition of skyscraper?â
And the definition you came up with was buildings that were at least 10 stories tall âŠ
⊠and structurally complete before the end of 1900.
Itâs weird that the history of skyscrapers is, to some extent, a lost history, that thereâs whole body of work that donât appear in those histories.
One of the problems is that the two areas where early skyscrapers were concentrated, the Chicago Loop and Lower Manhattan, have been heavily rebuilt. So most of those buildings are gone. One of the reasons the history got lost is that people donât know about what buildings they donât know about.

Still, itâs odd that something so familiar is also so elusive.
When you read the old descriptions they talk about the âcanyons of Lower Manhattan.â I live and work in Lower Manhattan and I wouldnât ever use the word canyon. But thatâs because weâve gotten used to what the setback zoning law in 1916 did, and the plazas from the 1960s. When I play tour guide, I take people to Thames Street between 111 and 115 Broadway, and I take them to Pine St. east of Broadway next to the Equitable Building. When you go to those two locations, youâre in the position that people in 1898 were in: having very tall buildings with no setbacks right up to the lot line on both sides of the street. Those are two blocks where you can re-create that feeling.
Are there buildings you discovered that surprised you? Hidden gems and oddities?
My absolute favorite building is called the Manice Building, which belongs to this weird class that appeared in New York only: skyscrapers that have the footprint of a row house. They are less than 25 feet wide, and less than 60 feet deep, and somehow 10, 12, 13 stories tall. The Manice Building was 17 feet wide and 11 stories high. It looks like a drafting error. It didnât make it 20 years.

Often when discussing the history of skyscrapers, fireproofing is mentioned as one of the things that made them possible. But what you point out in your book is that fireproofing also made them marketable, that it was like the LEED Platinum of its day.
Absolutely. It was specifically marketed the way things are marketed today: This is new technology that will make your life better. And it was.
The most interesting thing I read while doing research was the insurance report on the Baltimore fire in 1904. The Continental Insurance Company, which was a fire insurance company, had its building in Baltimore damaged. They sent Daniel Burnham, who had designed it, to survey it. His report was technically accurate but also pure propaganda: âLook how much better this building, using steel frame and terra cotta fire proofing (which I recommended), performed than its neighbor, which did not use that technology.â

The premise of the book is that it contains important information for preservation of old skyscrapers, but do you think there are lessons you learned in your research that would be useful to those involved with designing new skyscrapers?
There are fewer new ideas than we think there are. A lot of the very tall skyscrapers today are concrete core steel framing in order to get the rigidity for lateral load from the concrete. Theyâre a version of what I describe as the âcage frame.â It used to be that they did it with masonry shear walls. Now weâre doing it with concrete shear walls. One of the takeaways is just because something is obsoleteâand the old cage frame form is obsolete, no question about itâdoesnât mean that there arenât interesting things to be found by learning about it. And I think that some of the newer structural forms weâre seeing in high rises have their roots in some of the obsolete forms.
Letâs say Iâm designing a mile-high skyscraper in Saudi Arabia or whatever the current worldâs tallest building is. Do these 10-story-tall skyscrapers have a message for me? Is there anything the late-19th-century engineers would like me to know?
I donât know that this came from the research for the book, but whatever you think the last word is wonât be. Things will change in the future, and your building will be altered, and people will say, âAhhh, we can do it better.â
