Interview with Princeton University Professor David Billington for Program Three: “Bridging New York” Note: This transcript is from a videotaped interview for the “Bridging New York” segment of “Great Projects.” It has been edited lightly for readability. David Billington (DB): It’s a curious fact that at least the three leading bridge designers in our tradition in America were immigrants from German-speaking countries: Roebling, John Roebling then, in 1831, Gustav Lindenthal, who came over in 1875, and Othmar Ammann in 1904. And a major reason for that, I think, is their educational system. The fact that, at least in Roebling’s case and in Ammann’s case, they were trained in the very best engineering schools at the time. Those schools also, particularly in Ammann’s case, emphasized strongly the study of completed structures rather than just merely the tools of analysis, as so often happens in engineering schools. And so when, during Ammann’s education his head was filled with images of all kinds of structures and, therefore, he came with a strong urge to design large-scale works. So did Roebling. DB: What they found when they came to this country, these immigrant engineers, in fact in a way what drew them to the country in the first place was the wide expanse of the country which meant the wide or the great possibilities in building. And in the sense of New York City, for example, this river, the Hudson River, which was an extraordinarily wide river close to a major city. So that this was a great challenge.
