The First Skyscraper (in New York, anyway)

"The Birth of the Skyscraper / The First Elevator" Columbia University put this page together.

It's part of their "Architecture and Development of New York City" section, which probably explains why the article starts "The history of skyscrapers goes back to the late 1860s, with the construction of the Equitable Life Assurance Company's building on the corner of Broadway and Cedar Street." What city? I'd guess New York.
